Thread: heater and ac problems

good chance your blend door actuators took a dump on you.

here's the write up to change them. http://www.grandprixforums.net/blend...ent-21941.html if you take the glove box off and with the car running change the temp on the climate control and watch the little hole in the actuator to see if it moves at all.

you can also grab each heater hose to see if they are both hot, if so, the core is flowing.

or your climate control has died, or the outside temp sensors not working right.

not dumb at all. if you dont ask how else would you learn?

thats what we all do, try to save cash. my car has yet to be to a real garage since i bought it. only the alignment shop, thats it.

you can take off both heater hoses, off the alt bracket, take a garden hose to either hose, it dont matter, and flush the core, you should get the same flow out as what is going into the core from the hose. a nice medium flow works well, you dont want to get yourself soaked.

its possible that the core is air locked as well. so when you finish flushing it out, keep both hoses as full of water as you can and put them back on.

then bleed the coolant system.

that would be a vacuum hose. not sure ive ever seen a vac hose removed make the upper hose (im guessing to the rad) collapse.

most of the time they stall out if the vac leak is to big. i'd fix that vac hose either way.

if your stumped on the vac hose repair, post a pic of whats broken.

Sometimes that's all it takes. I had luke warm heat in my jeep and flushed the heater core with a garden hose and a ton of gunk came out of it. The heat has been perfect since.
