The £44.95 Kwik-Fleece deal is they measure the temperature at the coolest vent before starting (Mine showed 25c). The system is drained and a leak test is performed. If no leak is detected the system is replenished with gas and the correct measure of oil and the temperature at the coolest vent is measured again. If it's not 10% lower than at the start, you pay nothing.
All went according to plan. Final temp reading showed about 8c. Paid my £44.95 and away I go. I know it was working 'cos last sunday was a warm day and getting out of the car after the few miles drive home was like getting off a plane in a hot climate, the heat just hit me and I thought Wow..it's definately doing it's thing !!
The following day I notice things were not as cool as the previous day so I went back to K/F. They say they only drain, pressure test and replenish the system. They do not service or even check any other parts of the aircon system. They did re-check the temperature and it showed 27c (warmer than outside !!).
Any ideas what I can check with mine. The compressor kicks in ok 'cos the engine rev's drop very slightly when activated, This would not happen if the system had leaked 'cos the compressor would not engage.
I've re-synchronized the system as per the Handbook. Still no joy.
The belt went on a bit too easily and the tensioner wheel is at the highest point of it's adjustment, but surely I would hear it slip and would at least get some cooling but there's nothing.
Is there a fuse or connection I need to check and if so where's the fuse located and what connection should be checked ?

Check the HBV, and the vacuum to it...

Got a simular problem with mine, front blows cold, the rear burns the house down, its like being sat in the engine bay.
Its a trip to Vx for me tomorrow.

I'll watch this with interest, as mine did exactly the same.

No. It DID the same thing but remains non working at the moment. Reluctant to refill in case it is leaking. However kwikfit said it wasn't leaking. When they charged it it only took half a charge and only lasted for 1 day. It has returned to the way it was before, press aircon button and hey presto NOTHING!!
-
er...ok...but HBV ? Vacuum to it ??
-
i have a simlar problem my air con was not cold so did the same and took it to kwick fit but the temp did not drop so no charge,,, i decided to change the hbv which was fine and flushed the system now i have no heat when i flushed the system i used a garden hose on full could i have damaged somthing and since doing this i have a leak at the back of the engine not hbv think it may be oil cooler?? water in header seems clear???????? :'(

Two questions with respect to the heater bypass valve and a general thing to consider for anybody struggling with poor aircon and heat.
1) Was it a genuine valve or a pattern part from the web, motor factors etc as we have seen many of the pattern items failing very quickly (causing water leaks).
2) Did you connect the pipes back up correctly on the side of the valve with two outputs, the top outlet must go to the heater matrix and the bottom to the engine...
If item 2 is wrong, you heat your nice chilled air with the heater and when you want heat, the bypass stops warm water flowing through the matrix....

Is it possible to get a pic or a rough location of the HBV to enable me to check my pipes are the right way round?
thanks

At the very back of the driver's side bank of cylinders.

another way of checking the HBV is working is to select 'cold' take the trim panel off over the pedals on the driver side (3 plastic clips), start up and feel the 2 heater pipes as they come through the bulkhead. If the get hot (and the do quickly) then the HBV is not working properly, stay cold means it is functioning.
May be easier to establish whether the HBV works before you need to trace pipes in inaccessible positions.
also FYI, I've just had a problem with a loss of vac at the HBV, turned out to be the vac feed from the bulkhead to the HBV was partially dislodged leading to a blocked pipe. Difficult to spot as well....

Blower is blowing cold but the pipes in the footwell are as hot as hell, nearly as hot as the egr pipe :o
Does this mean my HBV is knackered?
-
I've just had exactly this problem. Could be the HBV or the vac feed to it
test the vac feed: disconnect the pipe from the top of the HBV, turn temperature to cold and start engine. Put your finger over the end of the vac line to see what you get. If you get vac then HBV failed or not fitted properly. If there is no vac then start working back down the vac line to find the problem,
Next connection is at the bulkhead. From inside the car remove the left hand vac pipe at the bulkhead grommet. You should get vac there with heater set on cold. THe vac to the HBV is controlled by a soleniod that is activated (on non climate cars) by two micro switches on the tem controls. It comes on only when BOTH are set to cold - you should also hear this click when you m,ove the temp switches
good luck and let us know how you go
-
Thanks for that. Is it a plenum off job to get to HBV?
-
Never done it so not sure. But I think it is a scuttle off job rather than plenum
You can get to the vac lines without taking anything off, just carefully reach in to the HBV
-
All the vac connections etc seem ok. Checked the one on the top of the HBV and it is sucking all other connections and pipes are secure. So from this I presume it to be the HBV itself.
-
i got a new hbv from vx gm part so should be ok im shure the pipes are correct but will check. the vac pipe on top is sucking should it suck on hot only or cold????
-
well what can i say :-[ pipes wrong way whos a silly boy oh well at least a have hot air again and i think i found my water leek seems to be the pipe that comes out the bottom of the hbv just at the engine i may have damaged it when pulling the hbv think thats a job for the weekend. is this hard to do it looks it any thanks mark i know check the simple things first well i thought i was right.....is now cheers

vac on means HBV should bypass the heater matrix

Ask Timbuk ;D

No, but easier if you remove the wipers then the windscreen scuttle panel. Gives a shout when you intend to do the deed. I can pop up and help out if you wish. :y

Vac on = no heat.....

Took my car back to Kwik-Fleece to see why the air-con stopped working after a day, and I left there with a distinct feeling of "We did the job, we had yer money...and now we really don't care !".
I took my car to a local company called Civic Rescue (Well, I think they're just in my area) and for £5-00 less than Kwik-Fleece they performed the same re-charge survice but with the addition of UV dye, and a 10 point pre-commencement check. The last thing they said as I was leaving is "Any problems, pop in and we'll check it again"
Kwik-Fleece checked nothing, just removed any gas in system, leak tested and re-charge. "£44-95 please...thank you, goodbye!".
It's been three days since Civic Rescue did the job and it's still working fine. I'm gonna give it a few more days and if it's still working then I'm gonna pay Kwik-Fleece a visit and request a refund cos I have done nothing at all to the system since it was done initially.

Hi, havce posted a similar rpoblem myself, my A/C stopped workinf after changing DIS pack.
Have since done cam cover gasket, breathers, plug leads & HBV as it was accessable at the time all goses reconnected as they came off. System bled, servos reset & still no A/C.
Compressor does not cut in at all. All fuses checked, even removed a cap & got a squirt of gas out to see if system had failed.
Once Mot passed will be next job to get ot booked in.
Of note i did get layout of vac pipes off here & all are present & connected correctly, Anything been missed????

Thanks. Not sure when I will do this, not urgent at the moment. Still got a drivers drop link to do. I have just got some new door cards (with the leather, for a small upgrade), sunroof motor and surround and a pair of front speakers to change. Got all the above for £50 :y Also having thought I had fixed the drivers door handle, it has developed some free play and swings a bit on closing, so I need to get that out and have a proper look too. Just the niggley little things.

HI Everyone
so, im just about to pop to Kwik Fleece and get me Air-Con regassed......but in a previous post i mentioned "burning smell" could this be my faulty Air-Con?
i came back from trying out one of these ARC Car washes near to me in Oxford, i drove 2 miles down the road and came back and there seemed to be a mild mist of "steam" coming from the bonnet
i will try it later, but i think my burning smell only happens when i have me Air con on....
if i go to Kwik Fleece, will they pick up on ANY problems with the Air con do you think?
thanks

Before getting A/C regassed, check your HBV!

whats a HBV? sorry !!!!!!
im the dumbest person on here and not mechanically minded, doh!
can a dumb person like me find it and check?

Heater bypass valve, if you click the link below you will see a pic
http://www.omegaowners.com/forum/YaBB.pl?num=1181719948
it sit right at the back of engine, drivers side, to make it easier to get to, you remove the scuttle
hth :y

THANKS MATEY
do i have to replace it?
how much is it?
do you think this is whats causing all my problems?
on that picture, could you put an arrow to where the HBV valve is?
i aint got a clue what im lookin for, as i stand at teh front of the car with the bonnet lifted, where am i looking?

Sorry, my mistake for using abbreviations (though a search here should have lead you to meaning) :-[
looking from front, its behind left bank of cylinders, under wipers and 'scuttle' (the plastic trim under wipers.
You need to check if its leaking etc visually - it may be fine. If you replace parts willy nilly, it will get expensive ;)
The part is about £30 from dealer.
Its fiddly to change, but with patience, easy.

look at the second pic, the valve is the thing with the 3 big pipes coming from it. Before I changed
mine I wriggled my hand under the scuttle and felt the valve for leaking water. It is possible, apparently, to change it without taking the scuttle off, but easier if you do. The clips that hold the pipes on are a pain to get off, I used mole grips to move them.
if you do change it patience and a box of plasters is called for ;D

i was just looking at my engine, just under the drivers side windscreen on the enigne and saw this tiny pipe not connected?
i cant find where it goes! is this causing any problems?

-
My guess is the top of the HBV.
Easy check is to set your temp setting to cold freezing or whatever, start up and see if you get vacuum at the end of your pipe. If yes and the vac goes off when you dial heat up then this is the vac feed to the HBV.

That looks like it might be the vacuum pipe for the top of the HBV. Look at the HBV on the engine pic
the top of it has a small pipe coming from it, see if you have one on yours, if not looks like it's come off.

The pipe in that pic is the auto box breather, just sits at the back of the engine :)
-
I reckon that vac pipe goes to main vac pipe which goes from plenum to brake servo. That would stop some of the vac systems from working well - hbv, multirams etc...
-
Cant believe how common a problem this seems to be!!
Just a thought but, could it be when we all do the breathers something is getting missed or put in the wrong place with regards to all the vacuum pipes?
I seem to think it stopped working after i'd done these and my cam covers...
-
So, should i be concerned about that "loose" pipe?
i cant see where it connects onto
or should it just be left loose?
-
Latest with mine after having it re-done with UV dye (NOT at Kwik-fit !!)....my air-con radiator (Intercooler ?) is leaking.
If the Kwik-Fleece offer was performed with a shot of UV dye I'd have saved myself a load of hassle.
-
I had my system refilled by a member here (Haydnmo) who works for kwik fit. Although my sysytem apparently has a leek he "persuaded" his machine to fill it up. 4 months on it still works just, but takes quite a long time to start getting cold. I never got around to finding the leak, but Haydon tells me that where the pipes pass through the bulkhead is a common failure point.
