I've had the aux fan stuck on high speed after washing the engine. It's the 3-prong electrical temp switch on the water neck, on the head, near the upper radiator hose (engine side). It might dry out and turn the fan off after a few days, it might not. That switch gets flaky after 15+ years and doesn't turn the fan on at coolant temps of 105C like it should, so it might be a good idea to replace it anyway. Pulling the 2-pole connctor off should make the fan shut off (if that is the problem). Now when I spray the engine, I always cover that switch - works great, no problems.

Don't know what happened to your A/C system - sorry! You may need to have it checked at a shop. Check all the fuses first though, for grins.
