It's a full size Chevrolet window van w/5.7L & 700r4 showing 80K miles.  After the accident with the deer the headlights are intermittant and no turn signals.  Fuses check out OK.  I checked the quad headlights and all sealed beams are good.  I checked the left/right side headlight grounds on the radiator core support crossmember and they are clean and tightened.  I did notice that the 4way hazard light indicators steadily stay illuminated when headllight switch is pulled on.  When headlight switch is pushed off the 4way hazard lights function normally.  I don' know if this 1988 has a BCM or not?  The only area I haven't checked is behind the damaged bumper.  It was pushed in about 4inches.  Could the headlight harness be crimped there?  The van is 45 miles out in the boonies at the daughters and she can't drive it with no turn signals or after dark.  Could there be a problem in the column?  The "highbeam" lever doesn't seem to "click" when pulled or pushed either.
