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.

Try this disconnect the heater hoses from the heater core use a hose to backflush the core. Then reconnect and try again.

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.

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

2005 Wrangler X a/c only blows from defroster


Check under your hood for a loose or leaking vac line , The A/C system on your jeep uses manifold vac to move the air mix doors and with no vac the air mix door will move into the defrost position. Find your vac leak and that will fix your problem.

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.

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.
