On my way to work today the knob that selects a/c, defroster, etc. seemed to be stuck at defrost and I couldn't move it. I pulled the knob off and put it back on and it could again move freely, however the next time I drove the car I had some problems with the climate control. When the knob on the far right is positioned up (off position) the a/c button and recirculation button are on and I can't turn them off. I can only turn them off when the far right knob is set to defrost. All other knobs and buttons seem to work okay and I don't know why this would happen.
Any suggestions?
