Okay, a few months back, I was informed that I need to change a few of my AC hoses and the Accumulator/Dryer and hose. I did change those and and got my system vacuumed and recharged with R12.

The AC was not blowing cold anymore but i was told to change the pressure switch/plug.

I did and it is still not blowing cold.

Does anyone have any advice???

I want to do this myself and not spend a ton of money!!!

i am sure the compressor is coming on but i will check when i get home. Everything was working fine a week or two ago before I did any of this. The only reason I change the above items was because my freon was leeking and those hoses needed changing.

Now they are changed and the car was repumped with freon and now nothing.

The compressor is coming on....

now you need to hook gauges up and read the high and low side pressures and see what they are doing

Ok. I will do that today.

I am trying to find someone that has the hoses to diagnose it. I will stay updated....
