AC. when it does work it is very cold.
What your problem is that you have a issue with the vacume system, what i did was removed the bottom panel on the passenger side looked up and you will see a bunch of wires, look for a black box (should be right above your head by time you squeeze in there and it has a yellow/amberish type of color you will see that you can remove this its a rubber piece cut the pink tube on the side about 2 inches away from the plug assembly, and slide it into the blue tube this will bypass all controlls and shoot the air out of the front vents, you WILL NOT beable to set it to defrost max/normal or htr (mainly which vent flaps are where) this has worked formonths and the a/c acts as if its on normal mode to use the heat just slide the switch :) until you can test all the other equip this will keep you cool or warm
