I know it's not a Corsa but thought some of you maybe able to help me.
Had my Air con On my Astra mk4 1.6 8v recharged last Monday as was empty due to fitting a new rad for it. I went to Formula 1 autocentre to have it recharged.
Filled the system with no problems. When they tested to see if it was working, all they got was warmish air coming out. They even had a good look to see what was wrong with it, they suggested it maybe a fuse or the clutch on the compressor.
Anyway got back home and I've had a look myself, I've checked the fuse inside the car they looked fine to me but I changed them anyway, still nothing.
I did notice that the clutch on my compressor wasn't moving whilst I had the car running.
Here's a list off what I've checked already.
I'm not getting 12v at the compressor terminals. I get the yellow light come on on the air con switch.
Here's what I could found when I had a look on Op-com.
A/C Coding (Air Conditioning), A/C Detected.
A/C Information Switch (Air Conditioning), Active 12V When it's off it's in active 0v.
A/C Load Signal (Air Conditioning), Inactive.
A/C Pressure, 1.80bar.
A/C Request (Air Conditioning), Inactive 12V.
Went back as I found a leak at the bottom of the liquid receiver, replaced it with one I had in my garage. Since going back I now have both the coolant and eml on.
Thought this had fixed it and it hasn't, so back to square one.
I've checked all fuses and there all good, checked to see if I'm getting 12v at all fuses. Only place I'm not getting 12v is the loom plug for the compressor.
Codes coming up are,
P1530 - (4) AC request line voltage low-present.
P1540 - Air conditioning pressure signal invalid not present.
Tried to clear codes and I'm left with P1530 - (4) AC request line voltage low-present.
Peruse is now around 6.8bar.
Sorry for the long post. Any help would be appreciated.
