can charging airconder have anything to do with overheating

If your car is overheating it has nothing to do with the air conditioner, it's your thermostat, you need a new one. They aren't very expensive nor that difficult to replace, well unless you're me, then forget it, I have a problem putting a quart of oil in my car. that's probably why it's such a piece of junk.

not true , yr air cond. runs on the same belt as yr water pump does if they removed this belt or adjusted it it may have cause yr water pump to malfunction . I would start with the thermostat since is very cheap ,but if the problem remains replace water pump and if the belt is skwelling that is also a sign sumthing on the drive belt is not working properly
