Hi Derrick,

From what you've described I don't suspect a fault with your air conditioning. When the compressor engages (both parts of the pulley spinning) it's normal for the engine revs to drop slightly. As you change the temperature display inside the car, the compressor may stop and start at different settings. This is normal.

As T-Cut says though, it sounds as if your resistor has failed.

If you tell me the colours of the wires which you bridged I will be able to explain.
