This is caused most often by out of phase climate zone blend door actuators, it is a very hard problem to repair, some luck in fixing it comes from removing the negative battery cable for 5 minutes to try and re-phase/sync the door actuators,if the one door will not change temp then it is more than a door sync issue and can require replacement of the blend door actuator, are the outputs of the 2 sides just reversed? that is to say will they change from hot to ac even though one is hot and one cold and visa versa?

Why does 1 side of dash blow hot and the other cold when ac is on with the dual climate control?


Check the actuator motor on the heater it directs the air into the vents. There is probably two of them be sure to check both. The motor makes the vents move and again directs the air where you want. Hope this helps.

Heat blows hot on passenger side but cool on driver's side


Most likely it is the climate control unit. Had the same issue with my 99 Regal, replaced the climate control unit and haven't had any issues since. Might try Digital Dash Solutions on eBay, they will ship you a refurb at1/3 price of buying from a dealer if they have one available. If not, they also have a climate control repair service. I'm not certain that they fix Pontiac products, but it wouldn't hurt to ask.

I have a 2000 pontiac grand prix with a digital climate control system. The heat quit working, it doesn't blow out any heat. Now that it is warm outside the air stopped blowing out any air. The digital temperature on the climate control is not correct. When it states that it is below 30 degrees on the ext and it is warm outside the air wont be cold. Once it starts going above 30 degrees the air gets colder. Today the blower stop working all together. Was told it maybe the climate control unit was bad. You can hear the door opening/shutting when you switch the temp from cold to hot. But there was no heat blowing out whatsoever in the winter time. Could you please give me your opinion on whether or not it is the climate control unit or something else?

2000 jeep grand cherokee limited with climate controle and 6 cyl. the ac blows cold on the driver side and hot on the passenger side.


If you have duel climate control, it sounds like the blend doors inside the heater box have broke. It is a rather large repair to do. If you don't have duel climate control, look for a broken, leaking or aged vacuum line under the battery try. Hope this helps.

Best of luck

2004 chevy tahoe, dual climate control, blowing different temps


Its more then likely the temp door broken or temp door motor broken/stuck. There is 2-3 of these motors under the dash on the side of the evap/heater core box. Some require extensive labor to replace, good luck

How can I fix


This is either an out of phase issue or a temperature control blend door or blend door motor actuator problem, it can also be the climate control module in the dash, 1st try disconnecting the battery for 5 min's to re-sync the climate control module, if this fails u will need to find out what blend door is the problem or if they are ok replace the automatic climate control module in the dash

U have a stuck air temp control blend door, either the actuator motor is defective or the door is warped and has jammed, one thing is that u must remove the dash to rcheck replace these parts.

2001 Acura TL Climate Control Blowing only Cold Air.


Ok it may be that the heater core bypass valve isnt opening. All that valve dose is when you turn the climate control to heat it opens a valve that allows hot coolant from the engine to flow through the heater core. What I would do is check that. It will be on the left side (passange) of your engine bay.You will see two black coolant hoses next to eachother and one will have a black box with a wire that runs to it. Have someone move the climate control from hot to cold to hot back to cold. If you dont see the wire move then you can move it yourself to open the valve.

Let me know if the valve opens or not using the climate control.
