Question about 2004 Chevrolet TrailBlazer

04 trailblazer, NO AIR coming through vents.

A/C and heat just stopped working out of the blue, checked all fuses and relays, they check good. I am thinking it may be a blower motor, What do you think?

Once a year you want to check the antifreeze/ freeon in your cooling system. from my understanding the cooling and heating system require this to function properly. they sell cans of this stuff at walmart that you can put in yourself.

The fan will not kick on...on my 2006 Trailblazer. Fuses look good along with the relays. The compressor seems to be working fine. Can't get air to flow through the vents.


The list of things that could be bad; blower motor, blower motor resistor pack (control module), resistor pack wire harness, fan selector switch and fuses. You say the fuses and relays look good, what does that mean? And which fuses did you check? Fuse for blower is in the underhood fuse panel and is #35.The relay is inside the control module, so you can not see it.

No air coming out of the vents


It sounds like the heater motor may not be operating. When you switch the heater fan on can you hear the motor running? If not then it may have blown the heater fan fuse, check the fuse's and then try it again. If the fuse is ok then it could be a faulty switch or fan motor.
