Ok, so I tackled replacing the heater and evap core in my mom's 2005 Jeep Liberty. Was not fun in the slightest. Anyway, so after replacing said parts. Hooked up a can of refrigerant with a gauge on it, showed nothing. Good so far right? So I add a little, compressor still doesn't kick on, go a little more till I hit about 35psi. Compressor kicks on, good. Then it shuts off after about 5 seconds and back on after about 5 seconds and continues to do this. Watching the gauge its going from about 35psi without the compressor running to virtually no pressure when it kicks on, which causes it to shut off. So I'm thinking it's still low, add a little more and then it still does the same thing just more pressure while the compressor is not running and basically nothing when it kicks on.
I know if there's too little pressure the compressor won't kick on, same thing if the pressure gets too high, but wtf am I dealing with here? I let some of the pressure out of the system cause it would go into the red area on the gauge if I turned off the a/c or the car. I'm at the end of my knowledge with the a/c system. Any ideas?
