A/C blows warm air.

I have a 95 nissan sentra. 1.6 engine, auto. When I am sitting in traffic my air condition does not blow cold air. When I am moving, my ac blows cold air. What is wrong

I was driving this morning and air conditioning system was working fine. Turned off car for a couple of minutes, then started the car, turned on AC and lights on dashboard for AC system didnt light up and AC didn't work, turned on heater and that didn't work either. What can I do?

Engine 1.6, AT, 327K miles (runs great)

I live in a very hot/humid location and my compressor is a new Nissan compressor. The dryer was replaced as well as the expansion valve. The evap coil was cleaned at the same time. Fans always operate when AC is turned on. Problem is that it only blows cold air in the early morning/late night. Daytime it's just cool, but not cold like all other cars are. At idle it goes from cool to almost warm in just a couple of minutes. The AC system doesn't leak and the pressures are good, btw, and the cooling system has never come close to overheating. I cleaned the orig. Condenser and it didn't help. I think it simply needs a new condenser, but my friend says if it isn't leaking then the condenser is fine. It has been like this for years with 3 rebuilt compressors and I thought a new compressor would fix the problem, but it didn't. Long freeway drives are a little cooler than city driving and much cooler than at idle. What do you think?

I just bought the car and the compressor would not come on because there was no freon in the car so I went and got some freon and now the a/c compressor comes on and the air blows a little cold but not as cold as I expected do u have any suggestions? Thanks

New compressor and added r 134

The air conditioner will not work on fan speeds 1 & 2 but works fine on speeds 3 & 4.
What is the problem?

My 1994 Nissan Sentra is having an air conditioning issue. It starts out cold, then minutes later it turns cool, then completley stops sending out cool air. Does it need more refrigerant and can I do it myself? I am very mechanically incline if I just get the directions. Thanks.

1998 Nissan Sentra Front Wheel Drive Manual 159000 miles

I have the old air condition system that came with this car, but it is know good. The cold air comes in cycles and only when the car is running. The cold air is never ongoing, like in most cars, which is what I would like. I was told because of the engine a 1.6, manual this would be all that I could get unless I upgraded to a better system. What would be suggested to upgrade too, even though the car is a 1998? I can't afford to buy a new car right now, so I am trying to make do with what I have, and the Florida heat without air is getting to me.

Makes really loud grinding sounds when turning corners or in reverse. Last night, after pressing as hard as I could on accelerator, the car will only drive 3-5 miles an hour. Also the AC only last 5-10minutes before shutting off & blowing hot air. I'm afraid to drive to mechanic for fear of breakdown. Can u give me an idea of what's wrong?
