Default curious sound at ingnition on
I have a sound under the dash that occurs on switching ignition on. No start required. Sounds vacuum related. No ABS on this ‘86. Anyone know what energizes at pos 2 that would switch some vacuum solenoid or some such under my cluster? Do the AC flaps adjust at this position?
