Sounds like a temperature door actuator! You'll need to get it diagnosed, but that's probably it! There is one on each side I believe.

Gene's right. You can try resetting the HVAC and see if the actuators will act right. Pull fuse #27 in the pass footwell for 60 seconds and replace it. That should cause the system to reset.

Mine did the same thing and all I had to do was shut off the engine and restart. Simultaneous Cold on driver and hot on passenger was wierd!

Do a search - very common issue. The likely causes are:

- Driver's actuator door gears are stuck. Try resetting the HVAC system as noted above by pulling fuse and letting unit reinitialize to try to reset door open/close limits. If that doesn't work, then door motor may need to be replaced.

- Some have commented that a system low on refridgerant can cause this - may need a recharge.
