Question type: Maintenance & Repair

wife ran it until it died with batt light on. I tested the alternator bad. installed new alternator
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
panel lights, power seat. I can find no bad fuses by visual inspection. Is there a specific
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
