Hi,
If you are referring to low air flow, the first thing I would check is the Cabin Air Filters, which are located at the back of the glove box. It you have not changed these filters on the last year or so, just replace them.
I have included a link that shows their location and how to do the job.
Good Luck, Greg
The air of your Chevy trailblazer 2004 blow out of the front vents when the air conditioner is on because the air condition is faulty and it needs repair.
yes
If the air vents of the Chevy trailblazer 2004 are not blowing air, have the fuel pump checked.
Check for a vacuum leak -sounds like it is starving for vacuum and reverts to the default position
my Chevy venture van's heater speed control stopped working so i don't get any air flow out of my front vents...how do i fix that.
When there is a problem in the vent system it defaults to defrost setting. Check the doors & vac supply
how do you fix chevy 20 ac to blow in correct vents
air want blow out vents
Your front blower motor has gone out. There is a front and a rear blower motor.
There is no heater matrix for the back air vents, only and evaporator for the A/C. My suburban always blowed cold until I added an extra rear heater matrix.
The mode door actuator has failed. We have instructions for repair at www.trailvoy.com
