91 Cavalier 2.2l Heater issue?

I actually got it fixed. It was the brwn-white wire going into my fuse block that was unplugged and just touching, so it was causing it to short there.

Thanks for the help

Can you tell me why I might be getting cooler air on vent with ac than when its on max?

Sounds almost like a vaccum issue, up to the right of the blower motor, there is a 3 hose connection, make sure all those are on the T and not off. I had that issue happen to me and thats what it was. If that doesnt work, let me know im sure i can find the answer for you

Well,I have to admit that there is a plastic vacumm line thats disconnected and cannot figure out where it goes. I dont know if it goes to the ac or not! I wish i had another cavalier to compare.

i can gaurentee that is your issue. If you are looking at the blower motor from the front of the car. Just to the right of it you should see a T connector where there will be 2 hoses going to it. When in actuality there should be 3. so all you have to do is plug that hose you have into the empty spot on the T. That should do it for you. If not let me know and i will see if i can find out what tube you are speaking of. That way i can find where it goes on my vehicle.

Its worse than I thought,the 2 plastic vacumm lines coming from the vacumm canister aren't even connected anywhere. I may have lost my T-connector. Can I buy another? well it also looks like there is a t-connecter there,but no empty spot,but the one that should be empty has a plastic vacume line in it where it looks like it was split.
