Question about 1999 Jeep Grand Cherokee

1 Answer

Dual climate zones. One hot, other cold, both set on high.

I have tried all sorts of different combinations and no solution. So what I have is one side blowing HI heat and the other Bitter cold even with both set on "hi". Is there maybe a vent that is not opening or closing somewhere in the dash or is this a CPU malfuntion?

Go to heatertreater.net. I bought one for my jgc and now it's working great. It's the blend doors that are broken. My has dual temp controls but it still worked for mine. The only thing is, the passenger side heat and air temp stays the same as the driver's side. Who cares!!!!!! It's warm and a whole lot cheaper than what the dealer costs. It took approx. 1 hour and $120.00 for the part. I paid $20.00 extra for express shipping. It's getting cold in Tennessee.

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.

I have a 2003 Buick Rendezvous. The drivers side blows hot air and the passenger side blows cold air. The car has that dual zone climate control. I have no clue where to start.


The actuator that 'blends' cold with hot is stuck in the cold position. There are a couple of options. Disconnect the battery, then drive the vehicle around without using the AC for 10 min, if the AC is defaulted to come on after a battery interuption, then shut the car down then turn it on again. You are trying to get the electronic actuator to reset and resume proper function. Another option is to try this: Start the car, adjust the pax side full hot, drivers full cold, wait 30 sec then shut car down, then start car back up and reverse the settings, pax full cold, drivers full hot. In both solutions, the vent actuators are stuck at either the full open or full closed, so you are trying to get it to 'self check' and allow them to resume proper function. After two years, I simply removed them altogether since I live where it is hot an only need cold.works just fine....

No hot air on driver side. Pasenger side has hot air.


if it has dual zone climate setting it could be stuck in the cool setting. if it is not blowing any air it could be the duct came loose and it is blowing the air inside the dashboard. it will require you to pull the dash apart to inspect what the exact cause is. it could be anything from a bad temp setting switch in the climate control panel to a bad vac line that that switches the air from hot to cold. any other info you could give me may help such as if it is full electronic climate or manual knobs, dual zone, is it blowing any air or just no hot air.

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

Ac blows out cold on dravers side hot on passenger side


If the vehicle has dual zone climate control, either the air mix door is broken or the motor that controls it is broken. It may also have the vacuum control system, which could mean a loose vac line or a broken diaphram. If its not a dual zone, then the air should be the same temp both sides as the mix door is one piece. It sounds like a mode door controller is bad, either case.
