Its zero degrees today and thick fog. Took the car out for a run to huntingdon (about 10 miles), before i left i ran it outside for 5 mins or so to warm it up. Temp gauge reached 85, with heater on Hi it blew cold all the way.
Stopped at McD for food, on way back, car never had time to cool down but heater, still on Hi, blew barely lukewarm all way back.
Thank god for heated seats.
Is an airlock in the matrix a possibility? Or a gammy HBV?
I would have thought on Hi setting it should blow quite hot indeed.
-
Is the coolant level correct ?
Too little water would show as no heat from the matrix.
-
Coolant level is fine, its one of the few things i keep a close eye on.

stupid plastic arms on servos popped off

Is that a common fault then?

Ask Miggy. He knows all about them. Seriously, it might be as well to drop him a PM as he doesn't get in here very often.
Having said that, if it works intermittently, then I doubt it would be the same problem as Miggy. Air lock sounds possible but you just backflushed the system didn't you?

I didn't but the garage that changed the headgasket would have emptied the system out wouldn't they?
Saying that, i didn't have a blowing exhaust manifold until they got their hands on it and i found the gearbox breather pipe dragging along the floor underneath the car..... Should i name them???

Name and shame. This isn't the BBC. ;D ;D ;D
I'm sure you've been reading the other heating related threads. Someone has back flushed their heater matrix in the last day or so to good effect. That and coolant change would be a good place to start if you're sure that the system isn't working as it should. :y

Well it doesn't really work intermittently, Shouldn't 'Hi' blow damn hot.... i tried cranking the heat down and up, and doing the A symbol with the circle round it (somebody else suggested that somewhere else on here) to trick the climate control.
Also blew into the sampling fan vent to see if the fan needed a helping hand....
Damn thing is beginning to annoy me now.

Nationwide Autocentre.... The only place that would do the work paid for by a warranty company... Incidentally i think i'll dump the warranty, its costing 25 quid a month
-
this sounds like the same sort of thing that mine does, i have a feeling that the climate panel is playing up and so send the wrong signals the the system.
i have found a sort of way round that work for me.
switch the climate on.
turn econ off
switch the recurc button twice you should have a A in a circle now.
wait for the heat, i switch the screen heater on
once the heat starts to come through i then switch it all back to how it was and it seems to remain
hope that helps
-
I tried all that as i saw your previous post :y and to be honest i'll try anything when i'm freezing ;D ;D
But to no avail.
-
As Martin says (Golfbuddy) if it works now and again it cannot be the flap arms, if it was all the time then i would check the arms on both sides.
:y
-
I'm kinda going with either airlock (flush out system), climate panel (beat fan into submission) or HBV (can wait until its not freezing to do that one)
-
Sounds like an airlock in the heater matrix to me as the coolant would have been drained to change the headgasket.
Check the two pipes going to the heater matrix, the two pipes that disapear into the bulkhead from the engine compartment.....if ones hot and other cold then suspect airlock in the heater matrix.......if both cold then check the pipes to HBV.......if the garage has had those pipes off and reconnected them up wrongly this will lead to strange probs with the heater.

Why not take it back to the garage where you had the HG done and get them to do the work for free?? If you're paying £25 per month for a warranty then I would claim on this as well. Must we worth a punt with the garage though first.
:y
-
Small problemo with that idea.
To be able to claim on the warranty, the service record has to be stamped up to date and its overdue at July this year.
Plus, as its done over 60K i have to pay £25 towards any repair costs.
On that basis, i may as well fix it myself, cancel the warranty and save the money....
-
I still suggest the sevo arms.
Lowest on each side are hot cold flaps (I think) both mine had popped off. Cold air only , irrespective of setting.
-
This was my problem, have a look.
