00 Grand Prix GTP - No Heat

[cherimehl]

Hi all,

I am wondering if someone can help me... My car has no heat! The blower works but it is just cool air coming out. I have in the last week changed the water pump and the thermostat and still no heat. Anyone have any ideas on how to fix this?

Thank you!

grab the heater core hoses under the hood, off the alt to fire wall, if both are hot when the cars good and hot. its the blend door actuators.

if cold, then take the hoses off the alt bracket, and flush one with a hose, make sure the core and hoses are filled up and slap them back on.

This is a very popular topic come winter, do some searching. The answers are out there.

Awww FFDP... Help a poor suffering GP owner out, you know most can't even find the search tool hehe... Let alone the first time posting!

Try what Scotty said, I think that's the way to go.

Welcome to the forums by the way and Happy New Year!

Thank you guys. I'll look into that. I am not very mechanically incline. So I don't quite understand what a blend door actuator is.

these little motors. http://www.grandprixforums.net/blend...ent-21941.html

they control the flow of hot, cold, or mixed air.

I could also be the whole heating and cooling unit inside the car, the thing with the knobs for controlling temperature and force of air flow
