Buick - Parkavenue :: AC Vent On Driver Side Blows Cold But On Passenger Side Blows Extremely Hot Air
Apr 17, 2011
I have a Buick park avenue 1998, 3.8L V6 engine. the problem is: The ac vent on the driver's side blows cold air but on the passenger side blows EXTREMELY hot air. no matter how cold or hot you set the ac it blows at the same temperature on both sides. Florida heat is setting in and my passengers are melting. I am really hopping that is not something to bad and that I can fix it myself. Tip: this started happening after i had the alternator and the battery replaced.

I have a 2008 Santa Fe Limited. Today I briefly turned the heat on since the outdoor temp was cool. Later in the day, I resumed the A/C AUTO setting at 72 for BOTH sides of upper vent outlets. I soon noticed that the driver's side blows warm air and the passenger side blows cold air as it should. No amount of adjusting the temp control either up or down had any effect on the driver's side except for constant warm air. Now I know the passenger side can be adjusted separately but both sides were set for the same temp. Never had this happen before. Always before, if I wanted warm air, the warm air would come through the floor outlets. What's causing warm air to come out the top driver's side vents when it should be cold? Could a diverter door be stuck?

My wife drives a 2010 Hyundai Elantra with a 5 speed manual trans with about 40K mi on it . We purchased the service maintenance package that covers all scheduled major and regular maintenance. A year ago they replaced the head gasket because they discovered a small oil seep. This was covered by the warranty.
Well a couple of weeks ago I noticed that the heat is fine on the drivers side and blows cool on the passenger side. This is a problem particularly when defrosting the windshield. When she brought it in for the next scheduled service a couple of days ago I asked that she mention this problem to the service people.
Their response was "we need to do a cooling system flush which would not be covered by the service contract" to the tune of a couple a hundred bucks. The coolant is the transparent green it should be due to it being changed one year ago so I have my doubts about it being the heater core.

2015 GTI autobahn w/pp. Couple of days ago i started to notice that the driver side air vents only blows out cold air even when the car is warmed up.
So I decided to try turning up the temp to hi for both sides, and i notice passenger side is blowing hot air like it supposed to while driver side is not. (this happens with and w/o AC).
This happens maybe 2/3 times i start the car, so I looked up online and seem to only find people complaint about air staying hot when temp set to low w/o AC....

On my 2003 GX 470 w/ 135,000 I have an issue that I can't figure out how to resolve.
The driver side lets out hot heat and the passenger side lets out cold air. I have the dual climate control and both sides are at MAX HEAT with the blower on HIGH. I have 2 vents for each the passenger and the driver.
The left side of steering wheel vent is allowing max heat. the right side of steering wheel vent lets out warm air. Not as hot as left side but warm. On the passenger side, its only letting out cold air and gets colder if I lower the temp on the climate control for right side.
Engine coolant is full, no lights on dash. Blower motor sounds like its working fine.

On my 06 GS300 135k my driver and passenger side blows different even though the temp setting is same. I have replaced Driver side Servo motor but no change. When heater setting is at 75, passenger side blows toasty, but driver side is cold. What else do I need to look at possibilities?

I have a 2009 Santa Fe Limited. Dual climate control issue. The passenger side blows cold air regardless of the temperature setting or mode. How to remedy this?

My 2009 silverado ltz is haveing heating issues. when you first start truck all work fine. After a couple min the drivers side vents loose heat and blows cold air. the heat on the pass side works fine. then the vent will change to defrost even though the display still shows its on vent. the only way to get it back is to mess with the vent control. then it will last about a min then back to defrost. at this point i just turn it off. I have already replaced the control panel to no avail ...

The A/C in my 2007 ES 350 blows about 20 degrees warmer out the drivers side than passenger side with both sides set the the same temp.

My dual zone AC started behaving strangely a couple weeks ago. Driver side is blowing cold but the passenger side is blowing warm ambient temperature air. I tried turning off dual and turning back on, manual setting both zones to same temperature, but the passenger side won't blow cold air. Sometimes after driving for a few minutes, the passenger side starts blowing cooler air but not as cold as the driver side. What could cause this problem?

clarification: temperature control works as expected on driver side. Only hot air comes out on the passenger side.
1. Most of the problems of this sort seemed to have been solved by replacing an actuator - air blend actuator, vent door actuator, etc are the terms used. Are these all different names for the same actuator? Or are there two actuators?
2. The problems occurs regardless of the DUAL setting so I think it is unlikely to be a temperature sensor problem.

I drive a 2009 Santa Fe with 51000 miles on it. Recently the AC vents on the drivers side blow air that is considerably warmer than the air on the passenger side.

Bought new oct.2012. Fiirst time used heat blows cold from one side hot from other. not consistent, will vary from left cold, then hot from right or the opposite. been fighting with chrysler from then till now. engineers know problem exists and are working on a fix. haven't found it yet. contacted chrysler numerous times, just get passed from one to another.

I have a 2004 Windstar that is nor behaving well. It seems to run ok for the time i have had it. Mileage not showing, error code for cam shaft sensor (It has been replaced), passenger window works intermittently, no display on stereo, Heat blows on drivers side while the AC blows on passenger side, Electric doors work sometimes.
Like i say, it drives ok but won't pass emissions and too many erratic problems to sell it. My independent mechanic thinks its the computer and said take it to ford. Cant afford for them to waste hours shooting down individual problems if they are all related.

I have an old 98 Lesabre, and it runs and drives great. When I first got it I had to do the Vacuum line mod on the programmer to get the HVAC to blow out the face vents. That was the best $1.60 and 30 min I spent on a car
That mod still works and was done about 1.5 years ago, the ENTIRE time i have owned the car the temp blinks when I start the car, but the HVAC has always worked fine so I paid no attention to it. That is until 3 weeks ago when I had to replace my intake manifold. I disconnected the battery without turning the system to "off". I have been doing a bunch of reading online, and it seems I may have thrown the system's sync off by doing this.
Right now my problem is this, colder air coming from the pass side then the driver’s side. When I start the car it will seem synched for a few seconds, then it will start blinking and both vents will go FULL COLD, eventually it brings the temp back up the d-side gets hotter than the p-side. I have done the following:
- gone through AT LEAST 50 on/off cycles
- Removed the 9c fuse to try to reset
- Pulled down the glove box door and watched both the upper and lower blend doors go through there whole range of movement (which they do)
- Tried to re-sync by pushing the temp full hot, then full cold a few times in a row.
Besides getting this scanned by a tech 2, which is my last resort, is there anything else I can do?

I have a 2004 Buick Century with about 48,000 miles on it..the A/C blows very cool but not cold,it should be colder..i also have a 2003 century that blows icy cold.. I hooked up a cheap gauge to the low side service port on both vehicles and got about the same reading. Other then being slightly low on refrigerant is their anything else that would cause the A/C to blow cool air rather then icy cold? The compressors seem to kick on the same on both vehicles. I really don't want to add refrigerant if it's not low...

My 2003 Buick Century heater works fine while accelerating but as soon as I release the gas the air begins to cool, swiftly. I have had the radiator flushed and the coolant topped off but the problem persists.
