My Omega now has a replacement aircon compressor (see aircon compressor removal thread). I can't use it though because the numpties at the garage have run out of gas for the system. I have to take it back tomorrow or Wednesday to be gassed up.

BUT, the power steering fuse is still blowing. Ive tried disconecting the driver's seat heater and the rear blind, but to no avail, the thing still eats fuses and it's a pain to drive, especially round corners!

I understand that there is a PAS relay which might be causing problems. Where is it located? Could I use one of the spare ECU-area relays that I bought in a job lot off eBay some time back, or is it a special relay.

Anyone got suggestions as to cause of this problem?

Nick, Sorry to hear that you are still having problems.
I had a similar experience about 6 months after I bought mine. I have no idea what blew the fuse the first time but I kept replacing fuses for a couple of days and they all blew very quickly.
If you drive one of these without the ps then you will soon have biceps like arnie.
The problem I had was I was replacing the fuses from a well known supermarket brand (i know .... cheapskate scotsman), and they were just not up to it.
So my question is : are you using a decent brand of fuses?
Ross

P.S. Glad you made it over btw.

[Nickbat]

Ross,
They are just unbranded under-the-counter fuses from my local car accesory shop. Did you "cure" the prpblem by using better fuses?


P.S. Nice to be here

[RossPhim]

Yes it did actually.
It's a long shot but might be worth a try.
El cheapo fixo.

Did you get genuine Vauxhall fuses or branded aftermarket like Lucas?

If this works, I'll wet myself with glee!

I think I went to a Vx main dealer, but don't tell the rest of the dudes on here, I'll never live it down.

If this works, I'll wet myself with glee!

I'd be carefull where you are when you give it a try then!

We like genuine Vauxhall parts. We just don't like their spotty tossers touching our cars....

[Nickbat]

Tried a genuine Vx fuse, but it still blew as soon as I switched on the ignition. I've disconnected the heated seats, rear blind and fag lighter - and still it blows.

Look like it must be down to the PAS circuit.

Does anyone know the location of the PAS relay?

Help urgently required as I need the car for a long journey on Thursday.

[RossPhim]

Is it fuse No. 14 - 30Amp?
Not sure on your spec, (it can't be far from mine if you've got a rear blind), but I have it protecting : power steering, lighter, rear window blind, air circulation system electronic air conditioning system, heated rear window, and heated front seats. Have you ruled out all the others as suspects?

I have no knowledge of the PS system, but does the fuse blow when the engine is started or when the key reached the last click prior to starting? If it blows prior to engine fire up it may point to one of the other bits of kit misbehaving.
I am assuming here that the PS circuit would only blow a fuse after the engine has been started. Can anyone confirm?

[Nickbat]

It is fuse 14, which is 20 amp according top the handbook. It controls PAS, cigarette lighter, heated seats and rear blind. Fuse blows as soon as ignition is switched on (last click).

The only wat to sort this is to isolate the item causing the problem.

Disconnect EVERYTHING relating to that circuit. Make sure you actually unpug all the items.

Then, plug back in one by one, checking each time.

A little time consuming, but really the only way to know for certain.

Oh, and the PAS relay is in the ecu box, can't remember which one it is though.
Someone who has the necessary software can tell quickly enough.

[Nickbat]

Thanks, Laidback.

I've already gone down that route and disconnected everything (including ciggie lighter) leaving just the PAS...and the fuse blows, so I assume it must be on the PAS circuit somewhere.

[Nickbat]

Hmm. Just checked the ECU relay layout on another forum ( and there's no sign of a PAS relay there. I seem to think I read somewhere, or someone told me, that it was up behind the glovebox. Just need confrimation before I start ripping it out!

[Nickbat]

OK, just phoned my local Vx dealer to get an idea of a price for a relay only to be told that there is no PAS relay on my Omega.

Run out of ideas, now.....

[Nickbat]

What a way to spend my holiday..

OK, I've just found out that the heated rear window does not work. There is no light coming on at the switch. The 40 amp fuse looks OK.

Weirder and weirder....
