G'Day Paul,
And I'm still not sure
And I'm still not sure
Does your engine and a/c cooling fan work when engine temp rises to about 200 F?Just had my 164 in to the AC guy for a re-gas and he says the condenser fan isn't coming on so the pressures are too high, and he can't do much till we rectify the issue. He hotwired the fan and everything came good, so we suspect a relay.
Where is the AC condenser fan relay located ?
Anything else which is likely to prevent the fan coming on ?
Thanks,
Craig,
Looks as though it's lost something in the translation
I'll assume for now that the "engine coolant fan SUPPLEMENTARY relay" is the one I'm after.
Thanks mate.
Beatle, can I ask how much the re-gas cost? Mine needs one (and I assume a new receiver dryer + r134a gas) but I'm afraid to ask how much it will set me back![]()
Roger Blue LeaderNO NO that is I68 high speed relay in two speed system see wiring diagram above. Now I1 is low speed relay but I suspect O22 low speed resistor is bad.
If when grounding brown (jumping) to black wire at Q22 trinary switch relay clicks but no fan comes on resistor bad, If fan comes on then check trinary switch when a/c pressure hits 215 psi.
If converting from R12 to R134a you should replace receiver dryer and use ester oil not pag oil.The guy only added about 12 grams of R134 before stopping due to the fan probs. He charged me twenty bucks.
Has your system been dead for a while ? If so you will require a rec/dryer, but you may find it's rather generic so it shouldn't cost too much. Labour and gas won't be much either.
If the system is still charged but low on gas, I'd get a recharge and maybe add some dye so you can runb it for a while to see if it has a leak, before spending money on a full service.
Yes you do, even though there are some differences in USA models (one on cardisc) over Euro spec models it is helpful. Andy told me he was making DVDs soon to cover all models but not sure when he is releasing them so check with him at www.cardsic.comRoger Blue Leader
Man. I gotta get me a CarDisc for this model![]()
I think it's got R12 in it - 1989 model. No stickers indicating it's been changed and the local fridgey says he can't get R12 at all.The guy only added about 12 grams of R134 before stopping due to the fan probs. He charged me twenty bucks.

Steve,Do you have two speed fan? Check thermal switch in side of radiator tank closest to air cleaner box. If three wire switch - red wire high, white wire low and black ground then you have two relays and a low speed resistor in fan shroud behind engine coil bracket and 50A L/H speed fan relays outer most relays next to engine motronic red stripe and fuel pump relays.
If you have single speed fan then one relay should still be near coil.

There is a bit of gas in it - the compressor comes on but I can't see any bubbles in the inspection port, so I'm stuffed if I know why it doesn't get cold (it gets, very slightly, colder than air temp if you wait long enough and you can feel the pulses in the hoses). I suspect it's been dead for at least 2 years though.
It seems there are now one or two R12 substitutes available in OZ, one is ER12 produced by Origin Link. A search on ER12 also brings up Hychill and they have an agent in Orange.I think it's got R12 in it - 1989 model.

Thanks for the tip Craig. The closest agent is probably Coffs Harbour for me (Armidale). Might ask the local guys anyway, it seems that they Hychill product would need a total evacuation of the system (kinda defeats the purpose, since it probably needs a new receiver dryer anyway).
Yeah the handbook is no use either. I guess I turn everything on and start pulling relays to see what goes off![]()
