#346 of 376 Have heat on Passenger Side but not Driver Side
Dec 28, 2011 (8:50 am)
I have an 2006 1500, last week hot air stopped blowing out of the driver side vents and continues to work on the passenger side. It has sporatically come back a time or two but is gone again after the truck sits for a couple hours. Any Ideas whats wrong or how to fix it?

If you were to email us the last 8 digits of your VIN, we could check to see if there are any open recalls on the HVAC. When you do send this email, please describe your concern in it (as it can be difficult to link emails to posts at times, and we want to be best able to assist you).

I forgot to mention that I did a radiator flush and I've kept checking the coolant levels and it is topped off. Still no heat coming out.

I'm having the same issue with my 2009 Sierra. Passenger side holds steady but the driver side keeps alternating between hot and cold on mine, even if I just have the vent on with no blower running. Sounds like the same issue you're having. Did you ever find out what it was because I'm stumped? Has to be a temp sensor somewhere that keeps triggering on and off. Do you have Dual Climate Control? Also, did the GM Rep ever get back to you?

As your Sierra is a 2009, this may still be covered by the Bumper to Bumper warranty. We can let you know the specific parameters of your warranty if you were to send us an email with your name and the last 8 digits of your VIN.

I think I found out on my 06 what it was, there is a connector just below the dash (easy to get to if you don't have the full center console) next to the driver side floor vent. It was loose like someone had stepped on it or pulled at it. I disconnected it while the truck was running, made sure it was clean and then firmly reconnected it. So far heat has worked on both sides for three weeks.

on my 2011 Sierra 1500 crew, I have had heat distrubution problems since day one. Plugged off center vents to get more air flow on passenger side. Helped a little, seems like to much is going to defrost or vents are to small to passenger and drivers feet. Its 30 below zero here in northern Montana again, so it makes the problem very noticeable. 100 miles from dealer have'nt had time to take it in yet, purchaced in Jan now have 27000 mi on it. Unrelated problems, gravel has beat out rear back up sensors, passenger wiper leaves last three inches of windshield not cleared, and fabric on seats is impossible to get lint and hair off. Want my 06 back! I've owned GM for 35 years, currenty have 6, this has been most disappointing purchase ever.

I am sorry that your 2011 Sierra isn't currently satisfactory for you. I see that you may be looking at taking it in to the dealership for the heat distribution concerns you described - please keep us posted on how this goes. If you are not satisfied after the visit, we'd be happy to help follow-up with you and your dealer and continue seeking to resolve it.

Thanks for the reply. Took vehicle in to Bennett Motors on 1/25, no problem with heater was found, they're going to look into it further next appointment. The other reason for the last visit was evap system was plugged and haven't been able to fill with gas. They ordered in canister, but forgot to order solenoid, so my day off work and a 100 mile trip was wasted, they did apologize. As you probably know this is a chronic problem with pickups and suv's forever. I've spent a 1000 dollars on my two 06 pickups for new canisters and solenoids. Van Motors in Conrad Mt has been smart enough to reroute hose to front of vehicle, so it won't plug again. Bennett told me GM is coming out with a reroute kit sometime. The other problem with rear backup sensors being beat out by gravel could not be fixed under warranty. I guess pickups are not to be driven off highway! GM really needs some protection for these sensors. Oh and windshield wiper problem, they put on new wiper and discovered it does not touch last 2-3 inches of passenger side either, so they went out to their lot and looked at other 2011's and discovered none of them touch. I can't believe I'm the first one to notice this! I hope you take this note as constructive criticism, I do like the power, the handling, and looks of my 2011 Sierra 1500 crew, and have owned GM vehicles for 30 years and would hate to switch to the F word. I'll be in touch with how heat distribution problem goes, if you have any ideas, you can contact Sheryl Mcallister, service adviser, Bennett Motors, GT. Falls MT. Thanks
