hello I have an 2000 rl and I've had it for 3 months now. when I first got it the mode button worked with no problem switching from head to feet. I usually keep it on full auto. but now I noticed the mode button doesn't work and the compressor stays on unless I hit the a/c button until it read a/c off. the compressor will stay on no matter if I have the heat or ac on but now I don't get the air to come out the vent and cant control the direction of air flow because the mode button doesn't work. any ideas? or should I just get a new control head?
