Can you run the AC with the roof down?
Does the car know when the roof is down and can you run the AC without a problem with it down. Dont want to freeze the compressor.

I think he is saying by leaving the roof open it will overwork the compressor and cause it to ice over or freeze.
I guess that all depends on outside weather. Right now I am in las Vegas 110 out and air conditioner is working very hard even with deep tint windows and screen covering the sun roof closed
I think we have too many variables such as speed of vehicle, outside air temperature humidity tint on windows and type of material, color of car etc.
I do not think there is a set answer, however if you open the roof why not open all the windows and leave the air off, vehicle is quite cool once speed is over 45

Of course you can run the A/C with the windows down. It won't do anything to any of the A/C components such as the compressor.
Remember A/C in car has been around for close to 50 to 55 years now. It used to be that the A/C just ran when turned on. All a person did was adjust the fan speed. Then they started putting temperature controls in. After that came what we have today in so many different vehicle and that's interior thermostats so you can adjust the temp. to whatever you want.
Just because the interior temp. cannot be obtained because the top is down or windows are opened dosen't do anything except keep the A/C running.
When I worked down in central Florida people use to do this pratice on a regular basis. Everyone use to drive around with the windows down and the A/C going full blast.
