Spider AC Failure
Summary of the thread
A 1998 Renault Spider is experiencing air conditioning failure, with the error memory indicating a refrigerant compressor failure. The AC doesn't cool or switch on, and a warning light is active. Possible causes include issues with the climate control unit, as suggested by a garage and confirmed by another owner with similar past issues. The recommended solution is to consult an air conditioning specialist or Renault expert to potentially replace the AC control unit.

Refrigerant level I haven't checked myself (don't have the tools), but the garage did a quick check and said it was fine. Compressor clutch looks okay visually. The garage suggested the AC control unit might be the culprit. Did yours end up being that unit?

Yep, eventually it was. I spent ages fiddling with relays and fuses, chasing down imaginary leaks. Turns out the control unit was sending bad signals. I'd recommend taking it to a proper air conditioning specialist or Renault expert. Probably not what you want to hear, but it saves a lot of pain in the long run...

Thanks for the insight! Guess I'll bite the bullet and get it looked at properly. The garage has estimated 980€ for the AC control unit replacement. Seems steep, but probably worth it to get the AC working again.

Sounds familiar. I've got a Renault Spider too. I had similar AC issues a while back. Have you checked the basics like refrigerant level and the compressor clutch? I hope you have, because I didn't, which cost me a fortune!
