I have had the same problem on both Headlights at different times on my 2002 Envoy. I had to replace bulb sockets. Sockets with pigtail can be purchased at most auto parts stores. Make sure to put conductive lube on terminals when reinstalling.

Lift hood, at top of each headlight assembly look for two L-shaped tabs. Pull these tabs straight up, this will release the headlight assembly. Lift assembly forward to gain access to rear of assembly. There two rubber caps, the top one is for access to the low beam and the bottom for the high beam bulbs. Remove the appropriate cap, grasp bulb socket and turn CCW to release. Unplug bulb from socket by releasing catch on side of socket, install new bulb, DO NOT touch bulb glass with fingers. Reverse steps to re-assemble.
Hello, try to start by checking the headlight relay and headlight fuse. You
also may want to check to make sure the bulbs aren't blown out. If those
parts check out to be fine and in working order, you may need to
replace the turn signal assembly in the steering column. This part
controls the hi/low beams. This may sound crazy but, when GM wired
their older trucks, they wired the headlights to go from the battery,
to the hi/low beam switch, then to the headlight switch (to the left of
the steering wheel) then out to the light bulbs. You can kind of test
to see if this part is good by making a fist and (with your headlights
on) gently hitting the plastic cover for your steering column that is
right behind your actual steering wheel. This could cause your
headlights to flicker on and off.
Check your headlamp relays under the hood, should be located on either the L/H or R/H fender well , could be inside a black plastic box labled fuses and relays... there will be a label on the underside of the lid to this box locate the relays as per lables... please rate my help thanks...
Open hood, look for two L-shaped tabs on top of the headlight assemblies, pull these straight up. This will release the assembly. lift assembly out as far as wiring harness will allow, look for a circular rubber cap on the rear side of the assembly, the top cap is for the low beam, remove cap and turn bulb socket CCW to release socket. Unplug old bulb and install new, DO NOT touch bulb glass. Re-assemble in reverse order.
