I prob should have given more info upfront but I was on my phone and rushing doing other sht.
I recently did some work to my A/C system. New hoses, new condenser, new o-rings, new receiver dryer. Took it to get charged and was told my the mechanic that the system held vacuum but when he charged it the schrader valves were leaking. So I went and got a kit of valve bodies and a valve tool. On the port that is the size of a tire valve i removed valve body that was missing a seal and was in bad shape. Slapped a new valve in no prob. But the larger port on the other line has no valve body in it at all. its like some type of trap door. It does not accept a valve like the other smaller port.
Also having a couple other issues im working thru as well. Of course the A/C programmer does not seem to want to send air thru the front vents, just the defrost and foot well vents are blowing. I have already fixed the climate control head unit and cleaned all the contacts & etc. All the buttons work. So I guess I gotta pull the programmer and try and figure out if its electric or vacuum or whatever.
The last issue was the PCM was not commanding the compressor clutch on. Tested the clutch and compressor and both work. but no current at the compressor. So I pulled the ac pressure switch and it has 12v on each side, but when I jumped the green white wire to 12v and bam the compressor engages. So I guess this means the switch is bad??
