check fuse or connection

Do all the other dash lights work?
If so, the LED display in the stereo may have burnt out

problem is most likely the wiper control module, not sure but check with your dealer for possible warranty.

Spark Plugs

Air Filter

Fuel Filter

could be a bad piston thats expanding as it warms up. take ti to autozone for a diagnostic test.

"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. : )

BUY JAPANESE

the circuit that powers the blower motor for the heater. if this is a aftermarket auto starter i sugjest taking it back to who installed it

check your fuses
