93 Buick Lesabre AC blowing hot air when stopped Sign In

I have 93 Buick Lesabre with 56,000 on it. Yes I said that correctly. The ac will work fine for a little while then when stopped at a light it begins to blow hot air while the ac is own. The fans under the hood are coming on but the temp light isn't coming on saying its hot or anything. I checked the radiator and its full. Could this be a water pump or thermostat problem by chance?? The reason I say this is because when it feel like the car is getting hot for some reason. Not for sure. Any expert help on this matter would be very much appreciated. personal info deleted Thank you.

I'm confused............ do you have an AC problem or and engine temp problem. What does the water pump and thermostat have to do with the AC?

I thought the car was over heating is why the ac was blowing hot. I checked things out a little bit ago and I was wrong about that. I am in vegas right now and its been about 110 out lately. I looked at the AC compressor and it looks like its old lol. Its only a 93 with less then 60 K on it. It shouldn't look like that. I am thinking now that I need to charge the AC probably or replace the AC compressor. When its on MAX AC during the day is when it blows hot out the vents. I went out a little while ago and put it on normal and it was blowing cool air just fine. It just seems it cant keep up with that kind of heat I guess. Its not as hot out right now either. I wanted to know if you think it sounded like a recharge problem or a ac compressor problem?? This car is in meant condition. Its never given me a problem in the last few months we have owed it. Let me know. Thank you.

There is no "sounded like" when it comes to AC. The system needs to be checked out by a competent AC shop that will analyze both high and low pressure readings and they will likely have to do a complete evacuate and recharge to determine exactly how much refrigerant is in the system right now.
