2008 XE AC issue
Hi, I currently own a 2008 XE 3.5 with 164k on it that is experiencing an AC issue that happened quickly. While my son was driving the car he switched the AC fan down from full high to low when the AC just stopped blowing cold. He had it inspected and found a blown 10 amp fuse which he replaced but it blew out immediately, car was hot. The next morning he replaced the fuse again, AC came back on for a few minutes but then the fuse blew again. He has also noticed that the radiator cooling fan is not coming on either.. Any ideas before I go and spend money to have this looked at? I seems like it would be a simple fix if someone can point me in the right direction.

Re: 2008 XE AC issue
Is this 10 amp fuse labeled for the AC system (compressor power) or blower motor inside the car? If its for compressor power, try removing the AC diode near the fuse - its labeled as a white arrow with a line across the point. The fuse box should have labeling to show which way the arrow points when replacing it. This diode acts as a one way electrical valve; voltage and current flows in one direction and cannot flow in the opposite direction. It protects the AC relay electrical contacts from arcing when ac is turned off. Diodes sometimes fail by shorting internally and allows current to flow in the wrong direction resulting in instant fuse blowing. When its removed, ac works. Replacement from junk yard (maybe any diode from any car with similar dimensions) or auto store/online.

The cooling fan turns on immediately when ac is used but only if the compressor runs.

Re: 2008 XE AC issue
Thank you for your quick feedback. I came home from work and tried your solution but unfortunately it didn't work. The 10 amp that keeps blowing is the ac clutch fuse. Any suggestions?

Remove the diode in the fuse box, replace the fuse and try again. Follow the rest of the previous post.
