  1. Ok guys i cranked the car up this morning and my heat was turned on but no air was present so i tapped on the climate control still no air do yall think it's the resistor acting up?? I had to cut the car off turn it to the on position i didn't crank it and turned on the air and i got air?? So i feel like it's a fan blower resistor problem any help plz don't wanna just throw parts at it to fix it??

Wait, so it started blowing air with the key in the on position? Sounds like your BCM is acting up..

Whack the dashboard hard (near the glovebox, not the climate control panel), when the engine is running & check if it starts blowing air like in this video -

Ok next time it dont come on ima give it a tap to see if it works again then I'll know for sure it's the fan blower motor but thanks alot.


No worries & good luck!
