Any ideas on where to look for a 5 push button A/C - Heater control switch for this car. The entire (switch/control) assy. looks like another push button AM radio. The left knob rolls a digit like and odometer to 1,2,3,4 for fan speeds. The right knob rolls other digits like an odometer and changes them sequentially from blue to red for temp control. The five push buttons select either A/C, Vent, Heater, Defrost etc. I would also appreciate it if anyone knows someone who reconditions these or has anyone got any experience working on these. Any help will be much appreciated.
