Ac and heat not coming out.

Hey guys, for a while i have noticed no air coming out of my front vents. When the heat is on air comes out of the top window and floor. Same with the ac and vent. It takes a lot longer to get warm and i just feel like im missin out.

Can anyone help me..?

yeah i gots the same issue im already looking into the vent work and fans and all that.. hope to find something... and let ya know.

Thnaks.. I am not mechanically inclined enough to take it apart myself. Unless i know it is going to fix something.

If you get r figured out tell me. Thanks

If i had to guess, i'd say your ac/heat blower fan is dead

I had the same problem! Turns out, an intake line for the vacuum pump had been disconnected and it was sucking in far too much air! There was a horrible piercing whisting sound coming from the driver's side under the hood, and I was also having problems with choppy acceleration and poor braking. I reconnected the line and my AC works again, and I no longer have problems with my brakes and acceleration.

this is nearly always a vaccum hose problem if you can hear the fan running.

the one running from engine side firewall to the spliter above the TB

OMG Finally! Thanks. Im not sure if it is the prob but mine is making a hissing sound at the drivers side also! Been doing it since i changed plugs.
Where exactly is the hose? Ill go look for the hose. Thanks in advance. Still tell me where it is tho..

Also my ac and heat worked kinda but it just doesn't come out of the middle vents. Maybe thats a different problem.. Also my fan, ac and heat is working fine. They just come out of the wrong places.

EDIT: I still cant find the hose but i can definetly hear some escaping air coming from drivers side behind the engine. I cant seem to find the friggin thing. PLZZZ HELP!

Darn... Wish i knew what a TB was... Approx how big in diamiter is it?

My problem started when my plugs were replaced as well!
The line that was disconnected on my car was light grey, and about as big around as a pencil and had a darker grey/black "L" shaped connector on the end. It was sticking up slightly and was located on the driver's side of the car. If you stand in front and look under the hood it was located behind the area between the engine and the windshield washer fluid container.
If you don't see it right away, you can try to find it this way: Make sure the car is running and the hood up, get a papertowelle tube, or something similar and hold it up to your ear and point it in the direction the sound is coming from. The louder the sound, the closer you are. Just PLEASE be careful when you are leaning over the car, you don't want to get yourself or your clothes caught in something!
Hope this helps! :-)

OMG thank you so much. I printed your post out and with a tube i found it. And guess what?? My ac works in the middle vents now! Yhesssss! Although my car didn't have any power loss from it it still makes me feel better wiout the horrible noise.
Tanks for the detailed post once again!

i had the same problem with my 88 the one vacum lllllline comes off just plug it and it works fine

common with all these and a lot of gms in general.

It will also mess up your cruise control on hills, not allow the climate control to switch vents. I'd replace the hose, cost about $0.40 at a store.
