Check for battery positive (power) at the headlight connectors, if you have power, then there is a ground problem

I'm not sure what it is exactly but I think it is a fuse or check your wiring from the lights on back. It should be one of those two. sorry I couldn't be more help.

So what do you see come on besides the parking lights? Do you see the high beams come on when you turn them on, do you see low beams or can you see the day time running lights come on (they are the ones that are closest to the grill). What have you done or checked so far?

open the hood and reach down to where the parking lights are located and give the plug in a 1/4 turn conterclockwise and the bulb should release from the lamp case. Then just remove the bulb from the plug that you gave a 1/4 turn to...and replace bulb. Then just put the bulb back in the casing and give a 1/4 turn clockwise to tighten. NO TOOLS REQUIRED

Make sure that ypur parking brake is completely released because if it is engaged even slightly the daytime lights will trun off. If that's not the problem then check the bulbs.

1985 gmc sierra light issue

The most simple solution to this Problem Which is VERY Common on this model Truck (Had a 85' Chevy) is to get an Electrical Tester from any Auto Parts Store or Wal-Mart and Unplug the Headlights one at a time and check the Leads in the Harness. If they test ok then go to the Fuse Box and Check there after you Pull out the fuse and reattach the Light Harness to the Bulb. There should be a Short under the Dash on the Stearing Column. It is a Task to fix on your own But, Can be done. I went so far as to Install a GT Grant Steering Wheel and REwired the Horn to solve that Problem. You could have messed up the Harness for these when you adjusted the Clutch But, These wires only go through the FireWall and Not under the Truck. Get a Tester and start Pokin around. Any good Parts Shop will be able to tell you how to work the Tester and there are all Kinds of MANY Price Ranges. Just let them know what the Problem is and they will know which one you need!
