Need some help please... :)
Hi,
The problem I am having is with my A/C & Heating. They both work but, it is either hot or it is cold and the air only come out on the defrost and the floor. ( I am wondering if this is a two part problem).
1. Either hot or it is cold ----- Meaning when i adjust my temp, everything from 60-85 is feels like 60,,, and 90 feels what it says.
2. Air only come out on the defrost and the floor ---- Is there a vacuum line or is there a module vacuum operated that may have cracked and not allowing the doors to move to redirect air?
Hope that someone can shed some light on this and get me pointed in the right direction.
C4 friend,
Wilbur

check the vacuum lines to the climate control.
If this is an LT1, remove the right injector cover and check for a black thingy between the injector pairs, but slightly to the rear pair. It's the AC vacuum check valve. They fall apart.

I checked it and it is broke. I am going by parts stores now to see if I can get one today. I bet it will be a dealer item but nice weather here in Alabama and the top can go down. C4 friend,

bogus,
I found a two way vacuum valve at the parts store. Air can now be directed where you want it to go. That took care of part 2 of my post above. Thanks again for that information!!
Part 1 is still needing attention. If you have any suggestion for that please let me know.

PS I also posted a new thread with a question, is a rheostat that worked with the temp adjuster to mix the A/C and heater to give the mid range temps?
