I have a 02 SCrew FX4 Lariat. Whenever I turn the ignition off the blower fan runs full speed and the only way to stop it is to pull the fuse or disconnect the battery. Has anybody out there had this problem and/or know any solutions?

 

Can you hear a hissing from under the dash in the fuse box area???

 

It makes a clicking noise under there sometimes.

 

Windshield/body leak. Does it happed after rain/snow/washing?? seems to be a common problem.

 

It started about a week ago so I replaced the battery and everything was fine until this afternoon and it started doing it again. It has rained here off and on for about the last month. The problem hasn't seemed real consistant with the rain, so to answer your question, I don't know.

 

I'm having the same problems right now. here's what I've found in this site:
