Can anyone tell me where the AC pressure switch is and how to jumper it to run the compressor to add r-134.

Are you trying to add 134A and having trouble through the regular port? OR, is you A/C panel out and you need to manually turn the compressor on?

My compressor clutch won't engage when I turn on the are so I want to find out if it is fust low on 134A or if I have an electrical problem. I have checked all relays & fuses. The panel acts as it should, no strange readout or anything so it may be just low on freon.

Probably. It takes is a few attemps before it kicks in if it hasn't been run in a while. Try turning the A/C button On and Offa few times while trying tu put some 134 in. May also be a bad clutch

I got some 134 & I hooked it up after a minute or so the clutch kicked in & a can of freon later I had cold air.
Unfortunately my wife took the car shopping & came back with a check engine light. The code says bank one lean. I think it's an O2 sensor but I'm not sure.
One more problem & this car is getting sold!!!!
