Does your husban know how to do electrical testing ? Find a wiring diagram , voltage drop test the circuit to find what's missing power or ground . The hit could have damaged wiring or ground . You can find a wiring diagram at http://www.bbbind.com/free_tsb.html Also watch youtube video on Mastering Voltage Drop Testing with Pete Meier and Jerry Truglia .

I'm not a salvage yard type guy--- but I sure wouldn't buy
much for a 1999 Jimmy

I have had a 1984 S10 Blazer for 28 years

I would get whatever you need at the yard,not new for those
prices

Headlight Replacement (Envoy)

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.

Thanks

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.

no the battery does not have to come out the grill in front must be removed .yhis grill runs through the headlight lens there ore 2 sqaure clips that hold the lens pull up on them slid out lens and get to the bulb should be 9007 bulb number.

check bulbes it is possible they both burnt out. check for 12V at the sockets .

first, did you touch the bulb with your fingers when you put it in? if so it is likely you blew the bulb, you can not touch the glass of the bulb.

If that is not the problem, make sure the wiring going to the socket is not cracked corroded or pulled out.

The headlights on the envoy are the easiest parts of the car to repair. You just pull the two tabs at the top of the headlights, screw out the bulb containers and you are good to go
