Default 90 Bonne.-heat/ac confusion

Right now the heat in my Bonne. is great, problem is, its spring and I need a/c. This has happened in the past and I have gotten something " unstuck" by pressing the electronic temp. control from 60-90 a number of times until it "unsticks" itself then it worked fine. NOT THIS TIME ! Any of you" Buds" out there have any ideas for me? Thanks alot ahead of time. Walt.

Default stuck

First of all welcome to the club.
It sounds like your air motor actuator is stuck. Take everthing out of the clove box, release the two top clips and swing it down. You will see a linlage lever on top of the duct. This should move back and forth as you change the control from hot to cold.
It may need a small push. If the problem persists the motor will have to be changed.
