fan switch

[tater]

so i was riding in my dads truck last night. (97 f150 scab 4.2) and the blower was only working on high. is there a resistor behind the fan control or is the blower motor going bad. any insight would be helpful.
thanks

try pushing the switch to one side or the other...if it works then you may just need to pull the face off and clean it...

i pulled the knob last night and cleaned it out with air and it didnt help
