My ac is only cold when I am driving, my heat is only hot when I am driving, not getting cold air or hot air in idle position?

Also, a loud squealing started after this and a mechanic unplugged my ac compressor but the squealing still happened after he did that. He changed the power steering belt, the alternator belt and the ac belt and then I went back 3 more times because it kept squealing, all but one time not as bad. The mechanic adjusted the belts and said it was the new belts loose after warming up so he tightened them over and over again?! One mechanic is telling me I need to replace my ac compressor? Another mechanic doesn't think its the ac compressor but isn't sure what it is causing the air and heat not to blow hot and cold unless moving and what the squealing is?

So many mechanics, so little consensus. Sounds pretty common.
I can't say as to why hot and cold only when moving, but it sounds like a weak performing system.
As for the squealing, I would suggest removing one belt at a time, and see if one eliminates the squeal. That would be the problem belt or pulley or component. Also, if you have any idler pulleys (a stand-alone pulley) on the belt system, be sure and check them as well. Spin them without the belt on, and see if they make any noise.
It would seem you need a mechanic who is willing to spend some time with you on this to find the problem. When you find a good one, you will know it by his output, and make yourself a regular customer. Good luck.

SOURCE: power steering noise

The belt is almost assuredly to tight and needs to be loosened just a hair. It is hard sometimes to get the tension just right. Try looseneing it a bit and hopefully that will help. I have had the same problem in the past.

check the tension. cheap belts will stretch. if after you retension them (especially the alternator belt) you may need to replace them with BANDO or OEM belts.

I have Freon in my 013 Nissan altama, but I only get hot air when I turn on my ac

Confirm your ac settings to cold. If you still get hot or warm air while cold ac is on, go and look under the hood and try to feel the low side pipe if it is cold or moist. If not, then look carefully if the ac compressor clutch is engaging or not.

Intermittant hot/cold air from heater

Had the same problem with my Mazda6 awhile back. Took it to the dealer and they found the radiator wasn't holding pressure. They replaced the whole radiator under warranty (WHEW!). Not sure how to check for that kind of thing, but it's a start.

Ac blowing hot air

This sounds like the mode selector is stuck on heat. Under the dash is the location of the hvac plenum and you need to check the cables and levers that are on it to see if they move when heat and cold are changed as well as the lever for where the air is directed.

Nissan 2000 ac hot when idle

the a/c condenser has a fan in front ( there is actually 2 fans if you sit on the car it will be fan on right side ) if this fan does not
come on immediately when you are parked and engine in idle
there is a problem with power to it, or motor failure. If you drive it
on the highway and a/c operates fine that's because air is circulating though condenser (thats what the fan is supposed to do at idle or slow traffic)
