I've had my car for over five years now and the A/C has never been working. Today i decided it was time to have a look at it, and so it begins..

When I press the A/C button it lights up but the compressor doesn't kick in, it does however when I override the clutch with a separate wire directly to the battery. No problems so far, there are however two more wires coming from the compressor, what are these for?

I read somewhere else that the compressor might not kick in if there aren't any refrigerant in the system.. is this correct? If so, how can i tell if there is any refrigerant in the system? I've tried to peek through the lens but I can't see anything.. I tried to override this by disconnecting a sensor on the lines (dunno if it was the right one though ) however this just started the fans so i suppose it was a temerature sensor or something..

Anyway, I then decided to have a look at the relays. I thought that the A/C button simply controlled the A/C relay which in turn controlled the clutch magnet.
This is where I completely lost my patience.. there are five relays, two of which belong to the ABS-system, two to the fans and one to the compressor.
I thought it'd be a simple matter of bypassing the AC one to see if it kicked in or not, but when I did so the friggin fans went on instead?! I concluded that the AC relay simply wasnt where the lid said but despite this I haven't made much progress..

if anyone has any ideas or possibly a wiring diagram it'd be really helpful

go get a can at wlamart and for 22 bucks you get a reader dial and if its low, refill it, and if its low the next day then you have a leak.

they have wal mart in sweden wow lol

I'm afraid we don't

It's nearly impossible to get a hold of R134a in Sweden without the right certifications, I suppose I have to get it filled at a shop which is ridiculously expensive

does anyone know where the pressure switch is located, it'd be nice to know if the refrigerant actually is the problem before I throw away 700$ on filling it

wow, sorry, did not realize. 700$ no way. ridiculous.

good luck

ty, but yeah, it's apparently illegal to fill without first testing for leaks so I guess it adds on


awww, I just had to press the link in your sig didn't I.. *uyuyuyuyuyuy, nannanaaa NANANA*
