A/C Doesn't Work With High Ambient Temps (Clutch/Field Coil?)
I have a 2007 Acura RDX with about 135,000 miles.For the first time ever my A/C did not work, it also happened to be the first time it hit 90F by me. When it was not working the clutch did not seem to be engaging, but I didn't think to listen for the field coil engaging when I turned the A/C on. I tried swapping out the compressor relay with another one, but it still did not work. The next morning the ambient air temp cooled down to about 60F, and the A/C worked fine. I could hear the field coil engaging when I turned the A/C on, and I could see the clutch spinning. When the ambient hit 90F the A/C no longer worked. I'm aware that there is a service bulletin for the Clutch and Field Coil. Before I purchase these parts and attempt to install them, does anyone have any input if there could be another issue?
