Question about 2006 Chevrolet Trailblazer

Blower motor problems/ac problems

Just recently my 2003 Chevy Trailbalzer (ext) blower sometimes does not hardly blow (heat or cold) no matter where you have the fan speed set. It will all of a sudden start working normally. And over the last few years just everyone once and a while when running the ac the blower would blow but no cold air would come on. Then all of a sudden it would get cold like its suppose to. Please help.

Blower motor wont run for the air or heat and none of the heated seatswork


I had a 2003 caddy dts same issue the blower motor has probably gone bad u can order them online. What u can also try is kicking under the passenger side glove box area that's where the blower is located sometimes they get stuck. Try kicking or tapping under there and see if it pops on. I did this with my car

2003 Chevy Impala w/dual zone heat /AC stopped blowing on speed 5. Worked fine on speeds 1 thru 4 for about 4 weeks then stopped working on all speeds.


Likely the blower motor resistor. located right next to the blower motor, this device is resposible for reducing the voltage suplied to the motor. when it fails you may loose some or all speeds of the motor

Heater only works on passenger side.


there is a motor actuator that moves these doors for hot and cold, two separate ones for either side. the motor unit for drivers side is no good and needs new one. replace this and all will be good.

2000 Chevy Z-71 A/C problems


maybe drop the blower motor and check the vents for obstructions. I worked on a friend's car this spring that had a two year-old repair bill sucked in to the blower wheel....it limited the air output but made a lots of noise in the process.

I have a 2004 Chevy Tahoe. The rear a/c stopped


This is something best done by a qualified repair shop . An yes it can have two different problems , not related ! Blower motors do go bad , or a control processor . Does it have manual or automatic HVAC . It would be to your benefit to have someone like this guy diagnose the problem . This is not for a rookie to try !
