Re: Blower has no speed adjustment

The saga continues... New resistor and it worked for a while. Now it'll cycle on it's own. Replaced it and the same thing. Replaced the AC/heat control module from rock auto DORMAN 599211XD. ran the configuration and it worked for a few weeks. Now it's doing the same thing. Talked to dorman tech support and they say I need a re manufactured 599009. WTH? I took my truck to work this morning and it was in the 30's. Blower worked flawlessly. Got out of work and it warmed up to the 50's. No warm air from the blower at the 70F range but if I cranked it up to the 80's it would get hot. Could it be the temperature sensor? If so where is it?
Any suggestions?
