I got the truck and my mechanic told me it needed a new fan blower as it was stuck at one high speed. then it stopped working then i heard clicking under the dash. now when i turn on the climate control nothing happens. ive read about the blend door actuator...im not too sure. i wanna be for sure before i go ripping out everything and buying things i may not need. i will say that the rear fans work but no ac, which the navi has been sitting for over a year.

 

If the blower is running at high speed then the motor is good. If you don't have all of the blower speeds then it's the resistor pack that needs to be replaced, not the motor.

 

yeah recently the fan wont come on up front. no clicking no noise nothing. the rears work fine.
