Why does the ac on a 1997 Chevrolet Astro quit while going up a hill?
If your problem is that the cold air stops blowing out the AC vents and transfer to the defrost or the heater vents, I have had this on my 99 Astro. There is a small vacuum line that runs from the Drive Side Valve Cover near the front across the front of the engine over the Air Conditioning components. If this line gets cracked or broken, when you are going up hill and the engine requires more vacuum for fuel there isn't enough vacuum to keep the Air blowing out the AC vents. Check the line for cracks or broken areas.
How can you fix your heater in a 1996 jeep Cherokee the air and heat will only come out from defrost no matter what the selector is on?
The mode door is vacuum controlled in the GC and the default fail position is defrost only. You most likely have either a vacuum leak or a broken vacuum line. There is a vacuum junction under the passenger side dash that kids like to kick and pull the vacuum line loose. That's the first place to check.
