Question about 2000 Nissan Maxima
I had the same issue with the car overheating going down the highway; however, at idle it would blow cold air. I replaced everything (therm., rad. hoses, water pump), then my uncle (certified tech.) told me (without even looking at the car) to replace the radiator. Yeah it sounds like it should be the only part left, but the explanation was at highway speeds your cars water has to run a different route through the radiator than when its idle. Even if you flush your radiator it will still do the same thing because you will only be flushing the coils that the water runs through at idle. So there is a clog in the one or more coils that the water runs through (restricting water flow) at highway speeds. When you turn your a/c on it creates more of a rush through the radiator and it can't do it because of the clog. Hope this helps

I have a 2000 with the exact same problem. It overheats when the air conditioner is turned on. I know it is not the compressor. The fans also come on when the air conditioner is on. Any suggestions of what this could be?

I had the same problem and took it into the shop. They said it was the air conditioning compressor. With over 200K, I chose not to fix. Don't know if it was accurate assessment.

It sound like thermostat problem, maybe it work too hard when you turning the cold air.
