85 300TD - Finally figured out why recirc flap would not work (for recirculating air) - Have rebuilt ac box (evap, vac pods, checked for leaks) in the middle of changing all hoses, compressor. Checked vac functions, flaps, found that the recirc flap would not open for recirc air. Installed new ETR - now it works.
Question - does anyone have wiring diagram for this switch - the one that hase thin "tube" going into evap box between evap fins. I just want to make sure.


Thanks Steve
