There are two things I dont mess with: Auto transmisson rebuilds and AC systems.


Becusae I dont have the right tools.


Go to a shop that will do a pump down and refill. There is a rather precise spec for freon. Might be $100-150?


Everything else with the AC- controls, sensors- all that I can do, but I just cant deal with the sealed system


Having said that, I know over-filling these can be an issue, but I cannot say that is what is causing your symptoms...
