Unfortunately the blend door is computer controlled, so it could be that. However, the actual flapper is vacuum operated, so it could have a broken vacuum line.

My blows cold and I hear a clicking sound from the inside...what could it be?


There are electric motors that move blend doors in your dash board. The blend doors control the heat/cool ratios as well as the location the air will blow from. It's very common for the doors to break or the motor to fail and require replacement which can be costly.

1998 buick regal gs heat blows hot on passenger side and cold on the driver side.


Same problem on my 98 Regal GS; remove glove box, locate the blend door actuator, (black odd shaped box with metal "ring"). Remove the box and manually turn the blend door shaft it was attached to. If you get cold air, it's the actuator you removed. About 30-40 dollars.

I have a 2003 Jeep Grand Cherokee Overland with automatic climate control. The drivers side blows cold air constantly. It has no heat.


sounds like the blend door motro may be bad, this motor is screwed to heater box, there are a few of these motors one for pass/side for hot/cold air then one to control position of air like defrost or vent or floor, then the driverside cold/hot air, i think this motor is on driverside part of heater box, to make sure locate each motor while moving all controls until you spot the one that doesnt move, then remove it and move door manualy to see if you get heat, then replace that motor, hope this helps,

NO COLD ON PASS SIDE A/C - DRIVER SIDE WORKS OK


Your truck has blend door actuators that go bad. each side has them . giving you the problem that you have. and in some cases the actual a/c control mod goes bad. Putting the truck on a scanner at the dealer ship they can look at each blend door and comand each one to open and close and find out witch one is not working. or you can buy the pass side blend door actuator / motor the one for the a/c heat blend door and replace your self its not to bad to get to on pass side. you can have them print you out a diagram when you buy it.

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


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.
