1996 LSS Climate Control issue.

My 1996 LSS climate control works great in the summer, but in the winter I get hot air on the drivers side and cold air on the passenger side. I manually have to pull the arm behind the glove box going to the damper door after the the car has been running for awhile to switch from cold to hot. This has to be done every time I restart the car. As an added bonus, the outside temp flashes about 30 times and then reads the correct outside temp.
Please help!!!:banghead:

If the outside temp is flashing, that means a code is set in the control head....
