Hi Monterogirl85 I'm glad to help!

If one of your vents is blowing hot air and all the others are cold, then you either have a A/C door problem or the Actuator Motor that works that door for that vent is bad. I see this problem a lot working on A/C problems all the time. This problem has nothing to do with a thermostat or anything else on the vehicle. It's only a door problem. You'll need to find out which door goes to that vent and remove the actuator and move the door by hand and see if it gets cold out of that vent. Hope this helps and have an awesome day.

SOURCE: How do you replace the heat thermostat on 01

follow the Upper coolant hose on the radiator to the engine block. it should have a couple bolts that hold it onto the engine. remove those bolts with the appropriate size wrench or socket wrench. remove the old thermostat and replace it with the new one the same way.

SOURCE: ENGINE OVER HEATING REPLACED THERMOSTAT,CANT

Your water pump is driven by the timing belt; to access you will need to remove the forward portion of the engine (pumps/alternator/belts and such) when replacing the water pump you wll need to remove and then replace the timing belt and tensioner. Much care is needed to to insure the proper timing or things can go very bad. On a scale of 1-10 (1 being the easiest) I'd give this a 6.5 to 7.

I hope this may have assisted you,
Tom

Driver side heat blows cool air passenger side blows hot air. Both thermostats are on hot, recently had no heat flushed radiator and got half heat

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.

    No heat blowing from vents already replaced

    I had a problem with that in January 2008, my thermostat was fine. I took my car in to the dealer and they said the hinge that opens and closes the hot/cold air inside the dash broke. They had to remove my entire dash and replace the part. Luckily I was under warranty and didn't have to pay but the repair would have cost $3000.
