ac not blowing cold on passenger side

My ac will blow ice cold on the driver aide and warm on the passenger side. I can hear the actuator open the blend door on the passenger side when changing from hot to cold. Any other ideas?


good gas mileage is highly overrated.

The actuator may be operating but the probable cause is the blend door is broken inside. The dashboard needs to come out to get to this door to fix it. This is not cheap to easy repair. This also appears to be a fairly common problem. Same thing happened to my 98 ZJ.

Read through the above thread. Try charging with refrigerant, worked for myself and quite a few others.

That's what I was going to try first. Going to have my mechanic empty and refill the ac refrigerant.

If refrigerant level was low then it would be blowing warm from both sides, not warm on one side and cold on the other.

If he has the dual climate zone AC, then it will blow cold on the driver side and warm on the passenger side when the refrigerant charge is low.

Nope, I had the exact thing happen a couple years back. Checked refrigerant which was low, filled and no problems since. When low, the ac will default cold air to driver side. I do not have dual climate control btw. Also, if any of the actuators are bad, there will be an annoying click/tapping noise which are easily tracked down.

This is a new one on me. Thanks for correcting me on this.
I apologize if I confused anyone.

Hey my '05 WK with regular old A/C not dual did this very same thing. I chased around trying to make it be a blend door or an actuator until it started blowing warm on both sides. Then the compressor went out. Lack of refrigerant ..... Big repair instead of a can of refrigerant.

Ditto, had warm air on the passenger side, was low refrigerant. Added some but of course means an overhaul is in order..

Having the same problem, dont hear a clicking from the actuator... and I had the refrigerant vacced and recharged. No change. Not dual zone either. Anyone know the location of the actuator if it's bad and if the entire dash needs to come out or not?
