ac problem There is only two thing left on my ls1 Fd. It is the ac and paint. The problem I have with the ac is when i went to charge the system the presure would be right were it should be but when you are looking in the sight glass there were bubbles. The manual for the fd says if there is bubble the system is not full. when i put more r 134a in the pressure would just rise, and not drop down.The ac clutch was engaged. The thing that got me was when i cut the motor off the pressure would rise. Is this normal? Thanks for your help

I don't think you can go by the sight glass deal for 134A. Typically you will see a 134A dryer having the sight glass covered over. Hopefully you have matched all your components for 134A? Expansion valve and all?
