2003 Chevy Trailblazer AC won't turn off

I have a 2003 Chevy Trailblazer and now my AC blower will not shut off. You can turn the car off and walk away, but it will not stop. We have taken the fuse out to make it stop. But what could be causing this?

Were you able to fix this problem?

2003 chevy trailblazer engine dies when ac/heater switch is turned on but blower motor is unpluged


The throttle body needs to be cleaned, grime in this area prevents the throttle plate from closing completely and allowing air to enter, making the air/fuel mixture lean. Make sure to clean the front and back sides of the throttle body. Also, disconnect the battery during the cleaning process to allow the computer to reset and relearn to the cleaned throttle body.

My 2003 chevy trailblazer makes a noise like pressure is releaseing as soon as turn the car off, What is this?


It is probably just your air conditioning. If you have your defrost on it also runs your ac pump. So if you have your ac or defrost on and you shut the vehicle off you will hear a hissing noise for about 10 seconds or so which is normal.

2003 Chevy TrailBlazer..bad rattling under truck and feet.


It could be a bad rear blower motor, or resistor? theres a lot under the truck that could make noise, have a repair shop check it and make repairs.

Bad Clutch Fan? Rear ac/heat don't work front only works on 4


The fan clutch isnt engaged at all times, therefore it may be normal to hold it in place (not recommended). On these trailblazer's 4.2L engine the fan clutch is electronically controlled. Usually when this vehicle's fan clutch malfunctions, there is a random ticking noise while idling or at a stop, also the "service engine soon" may turn on. As for the the fan speed problem, this may be a faulty blower resistor malf (typical) or climate control unit may be faulty. Hopefully this helps!!

2004 Chevy Trailblazer, At first you could only get the air conditioning to switch on by turnning the vehicle off and switching over to AC. Now the AC will not come on and it is always blowing hot air out...


Could be your main blower motor resistor, mine would still run the fan even after shutting off the vehicle.(safari van) Had to unplug the resistor to stop the fan,it was near the blower under the hood. Bought a new one for about $45 bucks. Replaced it and all is fine. Might want to check relays first, sometimes they stick and need replacing.
Good luck.

Blower control module


There should be a relay for that blower. sounds like the relay is stuck. see if you can find out where it is and replace it. You should find that info in a service manual for that vehicle. hope this helps: )
