Ok, last night I put some refridgerant in my A/C in my 91 Explorer. Its a 134a system and I filled it up to about 45 psi, this is what is considered "full". Now heres whats odd. When the AC is on, and the pressure is at 45, the compressor kicks on, but as soon as it does, the pressure drops to about 25 and it kicks off. After it kicks off again, the pressure rised back up to 45 again.
I know that AC repair is only to be performed by a tech, and I do NOT intend on doing reapirs myself, but I am going through school for Automotive Service, and I will be taking an AC class, so I am curious what would cause this to happen. I would like to know, and when it does come time to repair, I will either take it in and have it done in class, or take it to the shop and have it repaired. Again, I am NOT attempting to repair this in my garage, I am just curious as to what could cause this, I would like to have an idea before I take it to school or a mechanic.
Thank you
