2006 ml500 everything was working fine I put back the front bumper put on a/c it blows hot air. Hooked up gauge outside temp was 105F gauge low side 110 psi high side 150 psi intial reading. Washed condenser then low side was 98 and high 100, outside temp was about 101F. No difference on pressure when car started with a/c on or car not started, which is telling me compressor is not engaging. It had code stored ambient sensor and two other codes thinking it might have been old code I deleted them to rest the system. Now no codes at all. Checked ambient sensor as well connection is good and works well. Any info would be greatly appreciated
.
Update: ambient temp 106F without starting car low 98 psi high 151 after start A/C on low side fluctuate b/w 110 and 108psi high 151 psi
You probably forgot to reconnect the Outside Temp Sensor.
I had to change the radiator before and worked on the headlights that was why bumper was removed. After I finished the radiator I check A/C everything worked fine. I check ambient sensor plug and fuse 12 passenger glove box yesterday everything is fine.
Well, I'm pretty sure you didn't reconnect SOMETHING.
that is what confusing on the bumper there is only two connectors for fog and distance sensor's, only thing I did was change airomatic compressor since I just bought brand new one and kept the old as spare since it works then put back bumper and fender lining. Sometimes it has mind of it's own this car.
It will not load pictures of temp. Readings. What I noticed outside temp from local weather channel was 99F ambient on the car was +106F and my scanner started 107F then went to 117F.
and refrigerant psi was 130...
