Hello, this is cused by the drivers side temp door actuator. there are two electric motors that move the temp doors from cold to hot. there is one on the drivers side and one on the passenger side. you will need to replace the one for the drivers side.

  • Remove the left instrument panel (I/P) insulator.
  • Remove the knee bolster bracket bracket. Disconnect the electrical connector from the left air temperature actuator.
  • Remove the mounting screws from the left air temperature actuator.
  • Remove the left air temperature actuator.

    sorry about this, but it appears that 2 types of sealant have blocked your thermostat. You have lost circulation in your cooling system, you will need to reverse flush your full cooling system and have your radiator repaired or replaced. never mix your chemicals in the cooling system because there are 2 particular chemicals used in different products that when combined can blow up (nitro)

    Why would my heater blow out cool air when sitting still and then hot air when going down the road and then it's not all that hot


    Try flushing or blowing high pressure air through the heater core lines. its sludge build up and need to be flushed through heater core only. check antifreeze fluid level. only put in straight antifreeze, do not mix. most people do not know what mixture should be, so be safe and add straight, it will not hurt it, i run 100% straight antifreeze and never had a problem or worry about it ever freezing and cracking my block, heads or radiator cracking.

    No heat on passenger side and warm air on drivers side


    heater radiator blocked or partially blocked,drain antifreeze and save ,remove the inlet and outlet pipes for teh heater and flush in both directions repeatedly .brown rust should come out,if not a lot comes out then fit two pieces of pipe about a foot long to heater unit pipes and mix some caustic soda and pour in one pipe with a funnel till it comes up in other pipe leave for a while then flush again and you might need to repeat this two or three times

    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?
