Air conditioner problem

[minesapasty]

I haven't yet..... the fault is still there. Someone mentioned a sensor under the cover of the rear view mirror, and it can be removed, cleaned and then re-fixed..... just haven't had time to have a proper look. I have the next 2 weeks off work, so as long as I can avoid the wifes "to-do-list" I might get a chance to have a look.

TBH with our recent weather, I haven't really worried about it.

Not sure if this helps, but on the e53, if the front fan isn't working, the A/C won't work. Start your car, let it get to temp and see if the fan comes on. If not, then there is your issue. I bought my X5 and the dealer said "It doesn't have A/C that's why no one will buy it". I looked and saw the compressor so I knew it had A/C. Replaced the front fan, the A/C worked.

Make sure that's working before troubleshooting anything in the A/C system.

I just replaced my ac belt and now not blowing cold air. compressor clutch not engaging. fan is blowing hot air. through research I know fuse are 6,7,98,126 but with out cheat sheet not sure where they are located. I know 6 & 7 are in front box and 98 and 126 are in the back fuse box but dont know which slot. any help is greatly appreciated

I have scanned both sides of the sheet that is stored to the side of my fuse box..... I have a 2007 e70 3.0d..... Both sides of the sheet are posted below, just click on each of the links. Hope that they help.

I'm not convinced that the failure of the moist sensor would stop the AC from working. It would not start the AC on the grounds of fogging up but there's no logic in my mind in stopping it altogether.



Even if it is the compressor, these can be refurbished, be happy that it holds the pressure. The evaporator is a pain to replace if that is leaking.

I'm having an issue with my AC system that appears to be electrical. One day it just stopped working. I scanned and ran through some diagnostics and the system pressures are fine. It appears the magnetic part of the compressor is not engaging. Haven't had a a chance to complete the diagnostics requiring testing of resistance and ohms at the compressor. However an hour later after running the tests the AC started working again.

I've noticed the past couple of days sometimes it'll work and other times it wouldn't. I'm puzzled

id look for a bad/sticking relay...if one exists, in the 'magnetic part of the compressor'....

Thanks I'll look into the relay. I drove the car a few days and the AC worked perfectly until yesterday. Picked up my kids from school and there was no AC. Scanned the car when I got home and got the fault code again.
