Has rear air,and the blower still blows there. The front air sometimes will and sometimes won't work. It sometimes will blow if you turn off the recirculate button off, but not always. Any help of where to look would be appreciated!!

Ok, had someone mention to try tapping on blower motor and see if it would come on, it did. So is it still the resistor or could it be the blower motor. Just wanted to be sure, that motor runs a cool 100.00 YIKES!!!

If you were on speed 5, then tapping on it could have freed up (temporarily) the relay on the resistor pack. Still a possibly bad pack. Tapping on it as a fix is more likely to be oxidized/burning/overheated wiring. Get down there with a flashlight and look closely. You may have to rebuild the 7-pin wiring harness, and a replacement pigtail can be as much as the resistor pack. They DO go bad a lot.

Available on Ebay for $30, other places at higher quality for $55.
