hey all. my climate control has been a pain since i got the car. the main defrost dosnt come on. If i hit the buttons they switch sometimes but the defrost one rarely works. the defrost/feet works but then it barely defrost the window. now today my lights on the climate control are flickering when hitting potholes. is it time for a new one or can i open it up to fix anything. all help is greatly appreciated.
