Dear Sir/Madam,

The most common cause of these symptoms is broken blend doors. The HeaterTreater is an after market kit that solves heater and AC issues caused by broken blend doors .Also disconnect the battery, then reconnect, you have heat, but only temporarily. This is a factory defect and should be treated as such. Contact manufacturer.

Thanks
Good Luck

Heat not working on the drivers side


The heater core may be plugged up so that no coolant flows, thus no heat at all.

Heat blowing out drivers, but wont get HOT. cold air comin n on pass. side. help me?? antifreeze level is good. 2000 dodge grand caravan SE


Heat IS blowing out on drivers side, BUT it wont get hot ?
As long as you have heat, but not on passenger side, I would say your diverter is door is not operating, may be vacuum , or electrical, check under dash make sure no vacuum lines are leaking.

Heat not responding to temp control setting


it sounds to me like the passenger side control knob needs to be exchanged. This or there should be a relay in the line that is faulty. try wiring the driver's side control to the wires coming into the passenger side control. If this doesn't work, then it may be a computer glitch.

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.

A/c and heater


Is it leaking antefreeze?
The thermostat might be gone or needs a bigger thermostat
It could be a vaccum leak for the drivers side blowing cool air and the passenger side blowing warm air
Does it have dual air control switches one for drivers side and one for passengers side?

2001 buick century driver side heat/cool problems


Sounds like a problem with the "Drivers side temp actuator motor".
Each side has a motor that controlls the temp. door inside the dash for the driver or passenger side. These motors are approx. $75, plus 1 hr. labor to install. See more info here...
