intermittent blower fan
2002 Ford F150
Replaced the blower motor last year when it quit. It had had it after 270,000 miles. Well now the blower quit again. But then it started again! And quit again.
I'm thinking it's a bad connection, but where? Here is what I did to get it working again:
KOEO... went under the passenger side and wiggled wires... nothing. Took my knuckle and knocked on the bottom of the fan motor... it immediately turned on. Works on all speeds, just like it usually does.
Its just either on or off.
Surely the motor isn't bad already after only one year? Ya think?

Yep, the motor's bad or that would be my guess.
My Mark VIII Lincoln had intermittent blower operation but that was a generic problem of a loose connection at the blower. A short wiring harness that would correct the issue was kept in stock by the dealer because it was such a common problem.

Have you checked the blower motor resistor? I don't have a 2002 but it looks like the resistor is mounted to the back of the housing, so a knock could transmit to it.
