and fresh battery. Starts, runs, have hi and low beams,blinkers, brakelights, heater
blower. Have no taillights, power windows, door locks, radio, interior lights, instrument

relay or reset somewhere? any help greatly appreciated.

Did you check the fuse box under the hood? Also check the fuseable links down by the starter. HTH. -Jim
