1999 Grand am heat problems Sign In

New to the forums, and hopefully i can get some help!

1999 Pontiac Grand am GT
3.4L engine

--------------------------------------------

My heat does not work. I'm going to explain the best i can....

My cars heat does not come out when the car is in idle. When i started driving, you can feel heat coming from the vents, but very, VERY little. I can move the nob from 1-5 and it still comes out the same. The only time is doesn't come out, is when i turn the heat off, or i put the heat on MAX front vents(Theirs a setting for MAX to your face, or just regular, if that makes sense). It just stopped working one day. I just wanna know were i begin, or if anyone knows the best answer.


Just to add, i recently got my belt changed, because my some pulleys were bad. After getting the belt fixed by a mechanic, i drove off the lot, and the belt shredded, a little bit. It was still drive-able, but i still took it back in there. I found out my Harmonic balance was wobbling and caused it to shred a little bit. The car still drives fine, but it does squeak loud. Of course I am going to get it fixed, but would this cause the problem? I can't remember exact, but I'm pretty sure my heat went out even before i started having problems with my belt.


I'm sorry if my story doesn't make sense, if you have any questions, I'll be glad to answer. Thanks for the help.

Is this a blower fan problem? Is there a poor amount of air blowing out of the vents? Can you hear the blower motor fan change speeds as your turning the fan selector switch to the different positions? Are both heater hoses going into the firewall hot when the engine is at operating temperature?

I never checked the hoses to see if they are hot. I guess i never really checked the blower either. I can say for sure i do not hear the blower at all, regardless whether i change settings.

If the blower fan isn't working, you won't have air coming out of the vents. Without air blowing across the heater core and into the cabin, its going to be a mighty cold winter.

Which is what i dont get. When going at a fast speed, a tiny bit of heat comes out. Not enough to heat the car either. It's a tiny bit.

That is air being pushing into the cowl as your driving. You go fast enough and you'll get some air flow out of the vents. If you stop and you have no air coming out, blower fan isn't working or you have something restricting air flow. You stated you don't hear the blower fan running, so that is probably your problem. Now you just have to figure out why.

You could, but are you sure that is the problem? The blower motor needs electricity to operate.
