Well first off I will start buy saying I searched and cannot find a clear answer. The car surges badly when the ac or the heat is on. It is fine if they are turned off. The ac is not working and does not even cycle on when it is turned on. Is the ac compresser the cause of these problems? Does it need replaced or have nothing to do with the problems? I thought maybe a leak but no luck in finding one. I have done plugs,wires,cleaned maf,cleaned iac, no luck.

Is your A/C system charged? If it is and the compressor is seized, there will be one hell of a load put on the engine when the A/C is commanded to turn on. If the system isn't charged, the A/C should never even be commanded to come on. There is a pressure sensor that prevents the A/C clutch from coming on without refrigerant in the system.
