    weird ac/heat problem?

    hey guys,
    been experiencing another problem with my 01 cat recently. this time not radiator related. when summer came around, i tried turning the climate control down to 60 and found it was blowing really hot air, like the heat was on. however, when i turn it up to 90, it blows out semi decent cool air. the passenger side however is fine. i don't get it? i tried unplugging the battery for a while but nothing worked. any ideas? thanks!
    ~Dennis

    I noticed yesterday, mine did the same for about 5 min. The fan speed was on low and temp was set at 68, BTW I would not try going lower than that, it could never achieve it anyway. But it was strange anyway I turned off then on again then kicked the fan on high and it started working, maybe your compressor is not kicking on, or low on freon due to leak.

    driver's side screwed, passenger side works fine? check the vent door actuators, search this forum and there is a short writeup on how to get to the screw that loosens on the gearmotor and causes it to just flap around. Then you will have to re-sync the actuators.
