I have an 01 Expedition with 53,000 miles on it. It has the climate control that comes with the Eddie Baur Expeditions. The problem is when you turn off the truck and take the key out, the defrost will come on full blast and wont shut off. The only way to get it t stop is to disconnect the battery or take out the fuse. This makes it tough when its hot out and there is no A/C. Any suggestions? I was told it could be a resister on the Electronic Temperature Control Module.
