Ford Repair: A/C Blower Operation, climate control unit, grand marquis

Question
Thanks for your earlier response..perhaps I gave to much info.  The AC fan does not always work on my 2001 Grand Marquis. Only 19,000 miles.  I do not believe the switch to be the problem on the Climate Control unit as the relay clicks when turned to high.  As it is sporadic and returns to operation before it can be tested what else is the more likely problem?? Connections are factory tight. In your experience is the computer the more likely problem?? That is my question.

Answer
Hello and thanks for getting back to me....I'll try to help.
 Typically, I've found that the GEM (generic electronic module) is the problem. It should be able to be checked and have stored error codes, if there is a problem.
Hope this helps,
Erik
