    Need help with climate control

    My a/c is blowing warm on the drivers side and I have no codes but based on what I've read hear I removed the glove box and can see the actuator moving but I'm not really sure what I'm looking at. I was hoping to see a broken lever but the actuator shaft goes into this big box. Any input would be appreciated.

    Thanks guys.

    ------------------------------------
    assuming the temperature selectors are set to the same temp -
    and assuming the actuators are functioning properly -
    the most likely cause is a low charge of freon -

    connect a set of AC gauges - and report back with BOTH -
    the HIGH pressure reading - and LOW pressure reading -

    DO NOT BE TEMPTED TO JUST ADD SOME FREON -
    you could damage the system -

    and DON'T be tempted with one of those mickey-mouse "recharge kits" -
    with the el-cheapo gauge attached to a hose -

    I forgot to mention I've had the system checked several times since the condensor was replaced and the charge is accurate. This is a problem that comes and goes since I've owned it, sometimes just working the temp from 60 to 90 a few times corrects it but other times not. I did notice a paper clip when I took it apart and it makes me think someone riged it previously but I can't see where it may have connected.

    Definitely an actuator or sticking door.

    it's POSSIBLE the MIX - or BLEND door is sticky -
    give it a little shot of WD40 at the pivot points -
    and check around the edges of the flap for some loose foam -
    or some other obstruction -

    the other possibility - is a bad actuator -
    but that would usually set a code - or you would hear it clicking -

    Re: Need help with climate control

    I will try that as I did remove the rest of the filthy cabin filter yesterday. I removed it 3 years ago but when I was under there I noticed more was in there I removed like 1 and a half more so it could be junk in there. How do I access the driver side? Do I remove the side panel by the accelerator?

    Yes. Remove that panel and then remove the 3 stacked interlocking filter elements.
