Just recently purchased my second X5, 07 model and being the cooler weather I did not notice the AC was not cooling. Yes I have been through the endless climate program, lol, but to no avail, even have the AC light and MAX AC on. It appears the compressor is not kicking ether. Searching for this issue led me to check the coolant fan as I am to understand it will come on anytime the AC is turned, well it is not turning either. So hopefully someone can shed light on this as far if there is a relay or fuse to check. I best to start with the more critical cooling fan in case it could be the root cause of my AC problem
