I have a 1987 SS and I seem to be having an issue with my air condtioning, when I slide the switch to "max" the air is not coming out of the upper vents, still blowing out the bottom? Any ideas what to look for to make the air come out the top vents??

Thanks in advance

It could be a disconnected duct tube in the dash. Some older cars had flexible tubes connecting the vents. Im not sure how the monte is. Maybe someone with a little more 4th gen experience will chime in.

 

Thanks, I'll take a look under there tomorrow...

 

the only place i get anything out of is defrost and i cant seem to turn it on or off. my A/C is shot but i got good heat.

 

Maybe a vacuum tube disconnected.

 

i just bought my car bout a week ago and by looking under the hood alot needs to be connected, which i guess is the best way to buy a car with simple things like connecting the horn..haha, im gonna start workin on it tomorrow

 

Did you ever figure this problem out ? I'm having the same issue in my 87 ls . And being in hot *** south florida I would like the a/c on me and not my feet . . . Lol

 

i also have problem with my A/C. i'll leave mine to the max.
like in 5-15 mins. i'll heard the pop noise that A/C turn on
