You think that would make the fan stay on? I just had to replace my battery because it came on by itself I guess and it wiped out the battery over the weekend.This is the first gen section, but I'll venture that the fan/thermal relay under the dash is bad. There's is actually another name for it but I can't think of it right now.
Hi I was having that same problem. Everytime I would shut off my 2004 ram and take the keys out (if the fan speed wasn't off) it would continue to run on the set speed. There ended up being a problem with the ignition switch which I replaced with one from autozone which has a lifetime warranty and was only $40I have a 2004 Ram and the AC blower fan motor stays on all the time even when I shut off the truck and pull the keys. Any idea's? I have no idea what to do except to start pulling out the cash that I don't have right now. Any help would be great.
