The system could still be low on freon even though front works

SOURCE: front blower motor not working, rear works fine.

I'm looking at the circuit in a haynes manual and the 40 Amp breaker is the only one showing, but there is a blower motor relay in the power distribution center in the same area as the fuse, it might be that (you could do a temporary swap with another of the same type to confirm). I doubt the motor brushes are worn out already on a 2007,so I'm guessing if not the relay then a wiring problem or just a faulty blower motor. if you have a meter or circuit tester I would check the power at the blower motor itself to confirm wiring or motor. good luck

If you are refering to the 40 Amp "CIGAR" fuse under the left rear seat, this is the "main" fuse for the lighters. There are 2 more in the engine compartment fuse block. They are marked "C/LTR 1" and C/LTR 2". They are both 20 Amp fuses.

Got a 207 chevy tahoe ltz--rear air works ---front air does not work. any suggestions?


"2007 chevy tahoe ltz--rear air works ---front air does not work." Hi! I guess you are referring to the front hvac blower not blowing air at any speed and not coming out at any vents at any mode position. If this is the case, you can start with the fuses at the underhood fuseblock. Check out the three hvac labeled fuses. If found okay, and the hvac controller on your dashboard seemed to be working normally, you better check out your front hvac blower motor underneath the right IP section. You need to verify if power is reaching your front hvac blower when requested by the a/c blower controller. I hope you get lucky. If this is not for you, perhaps a few more detailed symptoms would be helpful. : )

it sounds like you have a crappy connection on the rear blower. i think your blower is on the right side rear. remove the panels and the blower is right in your face. check for voltage and repair the messed up connection.
