Heat works on driver side, passenger side blows cold air.

When the heat is on the driver side blows heat but the passenger side blows cold. It has dual climate control. adjusting temp has no affect

  • Anonymous Oct 21, 2008

    I have same problem on my 2002 Grand Cherokee. Just developed recently. The AC seems to work fine, just the heat is a problem. I suspect the IR sensor. Does anyone have any other suggestions?

Blend door for passenger side or blend door motor has failed. Very big job to remove dash and work on it. Except the door motor is accessable from the glove box.

Thanks for that. I checked with dealer, they state each actuator is $85 and that I likely will need a part called a "mid case blend housing", which is another $87. As bad as that sounds, it is still better than the $800 repair bill everyone keeps talking about.

SOURCE: heat works on driver side, passenger side blows cold air.

Did you check your coolant level or was it low and you added to it at some point? If so the system my need to be bleed or worst case the thermostat is going bad.

HEAT ONLY BLOWING WARM AIR ON PASSENGER SIDE

have someone check the driver's side temperature control doors, in behind the radio. there are two push rods attached to a plastic piece. the connector on one or both of these push rods, become unattached. leaving you with cold air. once that temperature door is closed you get hot air. passenger side still mixes, but not drivers. All or none for heat on Driver's side

Just had this happen today to my 2007 silverado heat on the right side cold air on the left side. After engine was off 15 minutes and restarted heat was on both sides. I'm guessing a relay failed to open door to allow the heat to flow thus blowing cold air.will monitor diligently for a while.

Driver's side air blowing warm, won't change

Sounds like there is a crack in the vent that leads to the drivers side, and hot air from the engine is leaking through.
