Bad switch or motor on other window Check to see if you are getting power to it - if so bad motor - if not maybe bad switch or open in wiring circuit
I would replace the master window switch
It depends whether or not your trailblazer came with heated seats, but if it did the switch would be on the door. The door switches should be (from front to back) Window Lock, Forward Window Controls, Passenger Window Controls, Door Lock, Seat Heaters.
bad window motor have it replaced.
Check the air filter.
Timing belt.
I had same problem -- fuel pump went out.
vacuum leak, bad idle control sensor
I found alot of Astro part at my local junk yard. most in very good shape. The only thing would be getting the correct color.
The year, make and model vehicle would help.
Check to see if the fuse is blown. Michelle Ress USA
