Buy a Ford. That's what I had to do after the compressor locked up, broke the belt, at 61k miles. Customer No-Service wouldn't do anything even though the truck had been in the shop 5-6 times in 1.5 years for your same problem with no resolution. Cost me $700 and I told corporate I'd never buy another GM.

Sounds like the fans by the radiator are not coming on. Check relays, wiring, fan motors, temp sensors, PCM.

SOURCE: Air Conditioner Problem

the most common problem here is a defective air temperature control blend door actuator, this is what moves the door that controls air flow across the heater core or the ac evaporator core, to replace this requires u remove the dash assembly.

SOURCE: Air Conditioner stops blowing cold air when vehicle is not moving

possibly low on freon. check for a/c oil stains/wet spots around all a/c connections. This will be where a freon leak would be.
Make sure cooling fans come on when the a/c is engaged.

Count how many times the clutch cycles in a minute. 4 to 7 is spec at 70 degrees F

SOURCE: Air conditioner charged won't blow cold air

It sounds like you either have bad controls or stuck dampers in your vents. The stuck dampers are usually caused by plant debris getting in to the air system.

Most likely it needs to have the freon recharged. This is very common with R134A systems. You can do this yourself or have a shop do. Doing it yourself requires that you locate the Low pressure line, don't worry, the recharge can adapters will only fit the low pressure side, and to follow the directions on the can and watch the attached gauge. Over charging your AC is very bad and can cause very expensive damage. All the instructions you will need for using the recharge can will be printed on the can. Follow them. If you choose to do the job yourself you can get the recharge can with Hose and Gauge from Walmart, Auto Zone or just about any places you can get Oil, plugs and Oil Filters at.

Suburban overheating and air conditioner blowing hot


If you have a viscous fan hub have it replaced as it is not working. The problem you have is that the engine is not driving the fan to draw air through the radiator when idling so the engine overheats . When moving the air flow from driving cools the radiator and so the temp goes back down. If you have electric fans have the codes read to find the fault or check why the electric fans are not working.

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.

The air-conditioner on our GMC Yukon does not blow cold when stopped at a light or such. The fan still blows, but the air is not cold unless the Yukon is moving. Can this be fixed?


Make sure that your coolant is full. That is usualy the cause.When you are at idle there is not sufficent coolant to be pushed thru the heater core.

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.

2005 Pathfinder Heat Flow problem


I am having/had the same problem. My rear heater has not worked the last 2 winters, still trying to figure that one out. But I think I solved the front heat problem myself. The heater was blowing cold air while idling and hot air when the car was moving.

I jacked up the front of the vehicle, took the cap off of the reserve tank for the radiator, turned the car on and ran the heat (AC off) for 15 minutes. This is supposed to release any air bubbles in the coolant system and I did see air bubbles emerge as I was watching (this might be normal occurance, I'm far from a mechanical expert). Anyway, this did not immediately solve the problem, still blowing cold air as it sat there idling after 15 minutes. Dejected, I put the cap back on, lowered the vehicle and resigned myself to taking it to a dealer.

But a funny thing happened the next day, the coolant level was a lower (no leaks on the floor) so I filled up, and sure enough, when I started the car and let it warm up a little, hot air started coming out of the heater!!!

As far as my wife knows, I fixed the problem for the price of a bottle of coolant, so I am a hero...but at first I thought it didn't work. Here we are a month later and still blowing warm air and haven't had to replace any more coolant...the internet is a wonderful thing!

Hope this works for you, and I hope I can figure out my rear heater problem as well.

I think you are low on refrigerant in the system, you may have a leak, you will need to hook up pressure guages to determine the exact cause.
