Hello,

Im still having problems with the #10 fuse, the blower and A/C clutch are NOT on this fuse, yet both stop working after about 10 minutes.

The heater control valve and pump are also on this circuit, disconnecting them hasn't solved this problem. The fan is also on this circuit, and it works fine.

Anyone ever heard of a short in the A/C switch control or how to diagnose it? I don't know if the temperature and blower control units could be the problem...

Do these control units or switch assy ever shory out? I'd hate to waste money on replacing it!

Thanks

The aux water pump can cause this as well as the aux fan.

Actually,

I have determined it happpens everytime the acceletor kick-down switch is activated....there must be something wrong in that kickdown circuit.

Tranny seems to shift fine...how do I go about diagnosing the trans kick-down?

Thanks

OH yeah!! There could be a wire pinched inbetween the trans body and the pan. Also the solenoid or the switch could be shorted.

I will check for that,

I recall I just changed the transmission fluid and filter about a month ago--- might have done something then inadvertantly...
