Does the a/c compressor turn on when you turn the a/c on?Are your electric cooling fans working under the hood?Have you ever cleaned the fins of your radiator and a/c condensor out?

Cooling fans are working. One of them wasnt working but found out it was just a connection issue. The compressor does not come on when I turn the a/c on. Everything is cleaned though.

With the compressor not coming on first thing you need to check is the a/c pressures.

If the a/c compressor is off the high and low pressures should be equal what were the pressure readings?

Are these readings coming from a a/c machine that recovers and charges the a/c?

So when you say the low side reads retard do you mean its reading as a vacuum instead of pressure?This is with the compressor off correct?

The retard is meaning too much pressure on the low side. And yes this is when the compressor is off.

When the compressor is off its going to read higher then it should when the a/c on it should 130psi like the high side. Your low side gauge must one of gauges that just reads blue yellow red. My gauge set reads actual pressure of both the high and low side.

It sounds like you have enough pressure to turn the compressor on. Have you checked to see if your getting power ground etc to the compressor when turn the a/c on?
