AC Problem

[LL6]

SSaSSy just let me know that her '00 SS is acting weird. Starting today when she puts her AC in high it kills her car. It won't start with the AC in high, either. It runs fine in the other settings. Any ideas?

Looking at the wiring diagrams, unless there is some sort of wiring short, the only thing I can think of is maybe the blower motor is bad. During "high", the blower motor gets its power through the same source as the IGN and ENG CNTRL Maxi Fuses. If the motor is shorted, it may be drawing excessive current (but not enough to blow the 40 AMP fuse) and robbing voltage from the IGN and ENG CNTRL circuits. I would try removing the Blower Motor relay and then see if it does it. If it stops, then it may be a problem w/ the blower motor, or the wiring in between the relay and the motor.

Thanks, I'll pass the word to FL.
