The a/c knob in the car broke off toward the end of the summer 2013. It has always been difficult to switch from air conditioner to heat. For a while pliers did the trick. When I got a quote from the dealership to change the knob I was quoted $1800. Now it is winter. It is freezing. I have no heat. I was pulled over by police because of foggy windows. I had no defroster because I can't turn on the heat.
The air and heat flow knob broke off as I turned it from cold to heat this morning. Now I cant heat up the car it is stuck on cold. Due to this the defrost will not work either. I have no heat in my car as of this morning due to the knob breaking off as I turned it. Part of the white plastic piece that attaches on the inside is now attached to the knob that broke off.
A/c, defrost control has been hard to change since purchase of vehicle. Plastic control for connection of knob broke. Called closest dealer (over 60 miles away) and they are aware of problem but will not fix because they feel that it is not a safety issue. I disagree. Cost for repairs quoted at over $600 parts plus labor. Without repair car can not safely be driven approximately 5 months of the year in this area.
Heater knob sticks, preventing ac adjustment to heat from cool. This prevents defogger system from effectively working hampering visibility, when it occurs while driving.
