Re: Renault - Espace - Air Conditioning's been a while but I'm back. Nothing's changed regards my air con...still not working. 2 colleagues have tried to access the cars computer using both a cheap code reader and also a snap -on branded one but neither could connect to it.
From what I recall I had 12v positive going to both wiring plugs on the compressor even if the car was switched off, making me think the earth might be switched..if that's feasible. Without being able to access the car's brains I can't tell if there's any fault codes that need clearing to get the compressor to fire up.
I'm going to (weather permitting) take the undertray cover off to access the compressor tomorrow and try and wire the compressor up to an external 12v supply and see if the compressor clutch then engages. If it doesn't then I know that the clutch has probably gone and I need to replace the compressor with a second hand one (can't afford a new one). If it does engage then a trip to an air-con specialists garage is needed to suss out the electrics to it. Then it's time get the system leak - tested. After that then God knows and ill just have to open the windows when it gets hot (no sunroof)
