No matter what setting, the driver's side would creep up and become hot.
I tried every fix found on the internet and ended up going to the dealer who replaced the driver's side blend door actuator at the cost of about $400.
It was fixed in late June and I haven't had a problem with it since.

Replaced the resister on fan motor housing and resolved the problem.
$26 part at AutoZone in stock.

#340 of 376 96 Chevy C1500 5.7L Heater Issues
Nov 29, 2011 (11:20 am)
I can't get my heater to blow out hot air. In the past month I've changed the heater core, the thermostat and water pump due to separate issues but I still can't get it to blow out hot air from the vents. It does blow out cold air though. I also hear what sounds like bubbling/boiling water in the cab when I'm driving (stepping on the gas only). I really need to get this fixed before the really cold weather hits. What can I do???

Sionce the heater system uses coolant to heat the air the most common cause of no heat is low coolant. When changing the thermostat, heater core, and water pump, the system needs to be topped off after the thermostat opens. If not you'll have low coolant.

Have 2006 GMC 1500 doing same thing. One thru four works but # 5 does not. Received letter from GM last week (special Bullentin 10240) on manual temp control switch. Gm realizes theres a problem with the hvac system not working on certain blower settings and would repair this problem if taken to GMC dealership. Took my GMC to Macon Ga. dealership and was told #5 was not in the covered plan to repair. Dealership said it would cost 328.00 dollars to repair. Can anyone figure this out?

I'm glad that you posted, Redge.
We would like to speak with the dealership to clarify a few things. Do you have an appointment already set up to have the repair done, or is your vehicle currently in at the dealership for repair? Please send us more information, including your name and contact information, the last 8 digits of your VIN and current mileage on your vehicle, and involved dealership. With this information, we will set up a case for you with Customer Assistance and will be following up for you with the dealership.
Thank you in advance,
GM Customer Service

Did you ever get this fixed and what was the solution? I have a chevy tahoe 2004 and I have had this exact same problem for a couple of years now. Thanks

Yes I did, after replacing 2 of the fan control modules I replaced the wiring harness at the fan. The stock harness overheats and melts, shorting out the contacts, bad design. Not hard to change, just have to pay attention, the replacement harness wiring isn't color coded. Can't remember if I bought the new harness on Rock Auto or off of ebay, but it was like $17.00. Good luck and Merry Christmas!
