2004 Chevrolet Avalanche Visibility (wipers, defrost, mirrors) Problems

“I was issued a recall a few years back specific to my vehicle about a blower motor operation malfunction. It stated that settings on the blower motor may not function properly. For example, when I turn on the air or heat I have settings for 5 blower motor options. All the settings 1-4 work just fine, setting 5 does not work at all. When I set HVAC to setting 5 no air blows out. I have since then misplaced that recall notice. If you have any information on this recall can you please get in contact with me thank you”

“My heating and air conditioning system does not function correctly. It has a mind of its own. It adjusts itself from hot to cold, cold to hot. It adjusts itself from low to high, high to low. Occasionally when I shut of the truck and take the key out the heating/cooling system will remain on. I can't drive in cold weather particularly in the morning or when its raining afraid that my defroster/defogger wont work because of the problem.”

“1) I haven't replaced anything, or done anything that would cause this to happen. 2) a-problem that im experiencing is that when my Avalanche is sitting still in the driveway the speedometer shows that I am doing 30 to 40 miles per hour. When I drive on the freeway it completely stops working and goes to over 120 MPH. B-my drivers side window doesn't work either, the motor slowly started giving out about two months ago. Now it doesn't work at all. …”

“1)windshield wipers will not turn off, and only work on 2 speeds. No variable. 2) I am unable to use wipers. From reading I need to take out fuse, and 3) have the circuit board replaced. Seems to occur frequently enough to be posted on several forums.”

“Nuts retaining wiper arms to shaft loosened on both driver and passenger side causing wipers to not move. I tightened the nuts as a temporary fix and will replace with lock nuts.”
