I would check to see if the coil is blocked with something like leaves or a flap that controls the air direction is stuck .

SOURCE: 1992 Jeep Wrangler heater not blowing hot air

How often has the coolant been changed? My only guess is that it hasn't and the hoses and the heater core are plugged up with goo and a flush is needed

SOURCE: Jeep AC blows cold air at defrost and feet but not through vents

There is a flap that directs the air. the flap is controlled by a vacuum actuator. This is located inside the venting. The actuator is connected to little vacuum hoses that attach to the temperature control switch. Either the flap is stuck, or the actuator has gone bad.

SOURCE: 2005 Jeep GC with 4.7. A/C compressor will not run.

Check the low pressure sensor and the hi pressure sensor to be sure they are operating properly. Also check compressor relay and all fuses.

SOURCE: 1998 Jeep Wrangler not blowing hot air. Fan is

your heater hose or heater core could be plug, or your flap that opens inside of the heater housing may not be opening like it should. It operates off a vacum line, check all your vacum lines going into your heater housing.
good luck

2005 jeep wrangler blows warm air not cold


Well this is different since most questions now are about no heat.
If one ac line is cold and the other is warm, I would suspect a blend door under the dash is not working. The blend doors direct air thru the heater core and the vents.

Compressor turns, holds a charge but does not blow cold air even when I turn on the outside air it blows warm air


OK, this is air-conditioning 1-0-1

You say that i holds a charge, and the compressore turns, but does the comprressor cycle on and off, as this is indicating that there is enough charge, and once there is low pressure detected, it turns the compressor on, and when it reaches a high pressure, the compressor cycles off.

Lastly, when engine running and AC on, if you feel the 2 pipes going in to the firewall, one should be hot, the other should be cold ???...is this happening ???

1996 toyota celica ac not blowing cold. freon is fully charged & ac compressor cluch is on but just warm air comes out the vents


The flap that directs cold air and warm air may be stuck in warm air position. This flap is controlled by a vacuum operated actuator that is attached to the vacuum lines and the control panel. This can go bad. Otherwise check in compressor sight glass to make sure there is no air bubbles or fog, that would indicate a leak in the system

Is the compressor engaging? If not he needs to find if a sensor issue if its fully charged or a low pressure or refrigerant condition. You can have pressure without refrigerant.

My ac will not blow cold air.it is fully charged and the lines are cold but will not blow cold air.the air is warm with ac on


First open the hood and find the a/c compressor. Once located leave hood open and then start the Jeep. With the air on look under the hood and see if the compressor is turning. Make sure not only the outer pulley is turning but see if the center in the middle of the pulley is spinning to. If it is not then it could be a fuse that runs the clutch for it. Check this out and let me know.

99 F250 diesel: A/C blows cold (fully


I think what happens is that you're burning out the compressor. If you got the windows down while you're blowing the a/c? it's working over time which is why they have two cycles. The image that displays the circle motion is meant for the windows to be up and the charge will last longer and with the windows down...click the one that shows outside air coming into the car. It might not be as cold as the other option but at least you'll have some cool air while you're at it.

Jeep Wrangler 03 A/C stopped working abruptly


This may be the AC compressor cycling switch is defective. It is located in the larger of the 2 AC lines coming from the compressor, it has a wire connector to it with 2-3 wires. To verify this is the issue jumper the connector with a small piece of wire and see if the compressor runs.
