ok got most of everything figured out. i found out that ac was a dealer install only. I dont believe my system was ever used before, I connected all electrical, hooked up a toggle switch for the ac to kick on. turned ac on by switch and clutch didnt kick on, out an ohm meter on the pressure switch and its at 650 some odd ohms. So the switch is off, jumped the switch to the get the compressor running and no cold air, i looked in the dryer sight glass and there is freon inside, but there is bubbles. I assume there is low levels of freon, But it has to go somewhere right? over 28 years and never being used shoud it still have a full charge? Any ways i bought a r134a freon recharge kit, and i think im going to replace the expansion valve and dryer for safe measures, Still not sure if they can go bad from just sitting. I also bought a ac gauge tester, going to hook that up and see exactly whats going on. If you have any answers to some of my questions that would be great. Keeping this thread updated to help other members diagnose there problems if they are the same as miine.

Ps whats the easiest way to get to the expansion valve, its under the dash correct?
