Heat coming from passanger side when climate control system on
\015 Unless I turn off the full system I get heat from the passenger side vents. I do get cool air on the driver's side with the AC on. The glove box is also very hot when running climate control.\015
I have seen this before. There is a vaccume controlled panel that opens or closes depending on the dash setting. In your car there are 2 seperate control panels,one for the passenger and one for the driver. There could be a loose or broken vaccume line on the passenger side control panel. It should be located behind the front passenger kick panel on the right side foward of the door. Sometimes you can here the leak. Sometimes if the leak is bad enough you have engine idle problems. It can also be the door itself. Sometimes the control linkage on the door breaks. It can be difficult to access these areas. A maintenance manuel for the car will be helpful. Good luck!
There are,what they call vent door actuator motors that open,and close the vents on each side these go bad time to time.If the glove box is getting hot,the heater control valve could be another problem also.First thing to try is,behind the glove box is a vacuum junction with a threaded stud(very small).There is a nut that holds the vacuum plug to the junction.It is on the stud.Unscrew it(it is time consuming).Then gentley,remove the plug.There will be little **** that align with the vacuum plug that could come apart,so be carefull.Use a silicone spray,and nothing else,and spray in the junction,and the plug real good,and replace the vacuum plug back as soon as you can.Do this as the ac is on and engine is running,so it will **** the lubrication in where it is needed.If it is a vacuum switch is stuck,this will make it start working again.Then ,if everything (vents and cool air)starts working,check the heater control valve to see if it is opening,and closing.The heater control valve closes off the hot water from entering the heater core,therefore,keeping the temp,in the air box from heating up.If I can help,let me know.

I have a 1991 cadillac sedan de'ville. The climate control system will sometimes put out heat and sometimes not. You can turn it all the way up on 90, but no heat will come out. Then, somedays it will put out heat. I have changed the thermostat, flushed the system, is full of antifreeze, and the water pump is new. Also the control panel seems to be working.

My 2007 Acura TL is having an air conditioning issue... The air is coming out cold from the two vents on the driver's side, but the air coming out of the passenger's side vents is very warm.

I have tried the dual setting, the individual side setting, turning just the a/c on with and without the recirculation option. My TL has the navigation system--if this provides any relevence to the p

When running the A/C on my Buick Lesabre, cold air only comes out of the passenger side of the dash vents. Warm air comes out of the drivers side. The car does NOT have the dual control climate system. It seems something may be blocked under the dash, keeping the cold air to the right side of the car. Any ideas?

The turn signals do not flash on the dash panel. I am stuck. Please help/
