As for heater controls, I have manual climate control. The plastic housing that holds the knobs cracked and caused them to be flopping around loose in the housing. I used some aluminum strips from the local hardware store to reinforce the plastic. I used one strip along the back and one along the front, sandwiching the original plastic housing in the middle. I drilled holes through the front metal strip, plastic and rear metal strip, then riveted the whole thing together with a hand pop rivet gun. It's holding up well.
