Intermittant AC Fan?

Hi,
I have an 89 F-150 4.9L, 5 speed tranny, 2WD.

I have replaced the AC fan/blower motor and the speed resistor switch and the dash switch inside the truck.

These were replaced within a year of each other for different reasons.

Now my fan works on and off as it pleases.

It usually works ok but is agravating, wonder if anyone has any ideas?

I would say you have a bad connection, check all connections including grounds.

Does jiggling the switch do anything, they are not typically an issue.

-Enjoy

Also recheck your resistor, it could be on it's way out again.
