SOURCE: Only cold air on passenger side

I would first check and make sure that you have enough Freon in the system, on climate control dual systems only one side will put out cold air if the system is low on Freon. Eventually, both sides will put out warm/hot air if the system continues to loose Freon. As with all leaks the system should be checked and then the leak causing component replaced/repaired.

Vent door between the two sides isn't opening or the flex hose going between the two is off.

The temperature actuator has gone bad. You will need to replace and have it recalibrated. You could try and disconnect the battery for a few hours and see if it will reset it's self. But you will be in the same boat before too long. And will eventually need to replace it.

SOURCE: 1998 Buick Century Air Conditioner not blowing out cold air

Under the dash behind the glove box(remove glove box)there is a vacuum connector with multiple vacuum lines of different colors,held in by a small nut on a long stud.Carefully remove the nut,and the vacuum connector,spray silicon spray into the vacuum lines,male and female ports.Replace the vacuum line connector back on.Also look for a vacuum line on passenger side of vehicle,near the firewall,and check the small check valve on the vacuum line and the vacuum line itself for sucking together,and breakage.If all this is o k,and the spray didn`t work,the control head for the temp control is not good

AIR CONDITIONER


Could be a list of things including low on freon, low pressure switch, relay, or the a/c clutch on the compressor.

Problem with heating and air conditioning. The driver's side is blowing hot air and the passenger side is blowing cold air


Air Conditioner blows warm air
  1. Air conditioner system is discharged. Have the system evacuated, charged and leak tested by an MVAC certified technician, utilizing approved recovery/recycling equipment. Repair as necessary.
  2. Air conditioner compressor clutch not engaging. Check compressor clutch wiring, electrical connections and compressor clutch, and repair or replace as necessary.

A/c blows hot air on drivers sde


The actuator door on the driver's side is out of position and needs to be reset. Remove the negative battery cable for 1/2 hour to reset the computer. Start the HVAC system and you should be able to hear the door adjusting itself and cold should come out of the driver's side vent.

This is just an idea, but if the a/c is working good, it may be the relay that changes your heater from hot to cold....give it a shot..just an idea....Please leave a good ratin, it is very important to me...
