STERLING STINGER Posted January 30, 2011 Posted January 30, 2011 rear parking lights are not working in my 88 i started the troubleshooting in the passengers side tail light ground...it looked a little corroded so i fixed it up nice, and mads sure there was a good ground to the bed... I'm gonna keep snooping around.... any suggestions would help.. thanks, Paul
Akula69 Posted January 30, 2011 Posted January 30, 2011 i started the troubleshooting in the passengers side tail light ground Did you mean the drivers side ground? If not, you might want to check behind the tail light on that side. Your parking lights are fed off of the dark blue wire in the tail harness. It makes several "stops" along the way, mainly for the plugs that provide power for the license plate lights. On my '87 one of those had become corroded inside the plug and separated the wire. These plugs are "bullet" shaped and the blue wire loops (enters and exits) inside of each one. Although I believe this is probly not your issue, another problem I had with the '89 was the bulbs were wrong. The PO had installed #1157 bulbs (which are dual filiment front bulbs) instead of #2057. Good Luck!
STERLING STINGER Posted January 30, 2011 Author Posted January 30, 2011 ya the drivers side ground... the tail harness is the group of wires running to the rear of the truck...right?
Pete M Posted January 30, 2011 Posted January 30, 2011 the connector for the rear harness is right behind the drivers side rear tire. corrosion in there robbed me of brakes lights a while back.
STERLING STINGER Posted January 30, 2011 Author Posted January 30, 2011 ok i tested to the harness and everythings good...constant power to the blue wire, blinkers all work good..etc... now, from the harness back i guess huh?
STERLING STINGER Posted January 30, 2011 Author Posted January 30, 2011 oh yeah, i also noticed that my top light is blinking with the turn signal light(middle one) ??????? I'm gonna check the bulbs what number bulbs should the top be...and the middle ones? thanks guys, i appreciate this... :cheers:
STERLING STINGER Posted January 30, 2011 Author Posted January 30, 2011 got it guys....couple salt infested wires behind harness... :bowdown: :bowdown: u dudes rule!
Pete M Posted January 30, 2011 Posted January 30, 2011 stop/tail lights are all the same double filament bulb, 2057.
