I thought it may have been a fuse. Maybe it's just coincidence. I have a 97 Ford Lariat. The A/C comes on, but blows hot air, and the doors no longer automatically lock themselves once I put the truck in gear, and start moving. The power locks work, but the autolock function of them does not. I am more concerned about the A/C, especially since I'm sitting my ace in Guantanamo Bay, Cuba! Any assistance would be greatly appreciated. There's one mechanic on base, and he doesn't have the best of reps.
