SOURCE: the ac only blows warm air, have recharged it with freon but it only cools minutes before blowing warm again, could find no leaks

There are special cans of R-134A with dye in them for detecting leaks. Most leaks occur around the fittings near the compressor. Recharge the system with the leak detector can or R-134A. There are also cans of R-134A with an additive to stop leaks. I would use these products to either detect your leak or to stop it. Best of luck.

SOURCE: After approx 40 min of highway driving the AC stops blowing cold

This is a problem solved by moderation. There are pressure switches in the system which cut off the compressor for too high a charge and too low a charge. The unit is suppose to cycle between a predetermined range, a moderation between high and low. If you were having problems before replacing the freon there is at least 1 pressure switch that could have been your problem in the beginning. If you have a manifold guage which shows high and low pressure you can tell when the pressure switch is open or closed. Some switches and for sure the autoparts store selling them can tell you the op[erating range of your switch. You can try just replacing the low pressure switch and fly blind without the manifold guages. Know how many ounces of Freon you put in? Compare to specs to see if you overcharged.

When they refilled the refrigerant did they put die in it to check for leaks, it sounds like there may be a leak.

SOURCE: air conditioning blows warm at idle cool when driving

hello there:
you may have a blockage in the system and then again it could also be low on freon and may just need to recharge and i would suggest taking it to an a/c repair shop and have them do a diagnosis on the a/c system it should not be more than about $150 for them to check system and recharge the system unless you have other problems hope this helps you out please leave a review thanks sincerely D.Jones

A/C Blows warm when idle


I can't say much without having the actual code.
When the ac stops blowing cold at idle, the most common reason is not enough air flowing thru the radiator, or the radiator fan is not running and the only air flow is when the vehicle is moving.

Why would my heater blow out cool air when sitting still and then hot air when going down the road and then it's not all that hot


Try flushing or blowing high pressure air through the heater core lines. its sludge build up and need to be flushed through heater core only. check antifreeze fluid level. only put in straight antifreeze, do not mix. most people do not know what mixture should be, so be safe and add straight, it will not hurt it, i run 100% straight antifreeze and never had a problem or worry about it ever freezing and cracking my block, heads or radiator cracking.

Nissan Altima no cool air blowing or hot air blowing


Hi!
It appears we have an Air lock scenario and you will need to perform a system Bleed.
Park the vehicle on level ground, when cold remove coolant filler cap, start engine and leave to idle, turn heater on full and blower to max. When engine reaches operating temperature watch and listen near coolant filler, keep clear as gurgling and hopefully a boil over should occur. Top up with very warm coolant and wait as it may do it again.
Check for heat inside vehicle if warm replace coolant cap but keep an eye on temperature gauge as the ~Air lock may have moved on from heater matrix/core so proceedure needs to be carried out again from COLD.
