AC problems
 

my ac only blows air when i get driving about 40, if im at a red light i get no airflow. any ideas what could be wrong?

have you checked the base of the windshield for debris that is cluttering the air intake?

yeah, thats not it. im leaning toward the blower motor being broke

if the blower motor didnt work you wouldnt be getting any airflow at all at any speed. Your problem is either restricted airflow into the plenum or lack of vacuum needed to draw open the blend doors.

its not much air flow, just enough to feel.

ah21283,

I am sorry to hear that you are experiencing this issue. Have you had this issue diagnosed at your local Chevrolet dealership?

Thank you,

do you hear the blower motor fan in all of its settings? from low to high? if you cannot hear it it may NOT be blowing OR the resistor block may be toast.

i hear nothing from 1 to 5. thats why i think its the blower motor

is there any way to know if its the resistor? or do i just have to buy a new one and see?

What I'd suggest is apply 12 volts directly to the motor, if it dosen't come on, either the motor or a ground issue
