How do you Change, Replace, or Install 1998-2004 GMC Sonoma Headlight Replacement





Tools required:
  • None


Step 1: Lift the vehicle's hood.

Step 2: Lift the tabs to disengage the retaining clips. There will be 2 of them.

Step 3: You can now remove the headlight assembly.

Step 4: Disconnect the wiring harness from the headlight assembly.


NOTE: If you ordered your replacement headlight from Go-Parts, it likely includes new bulbs, as most of our models do. This saves you an installation step! However, if your particular model does not, simply transfer the bulbs and sockets to the new assembly. This process takes just a few moments! Also, you may need to transfer the mounting bracket, but this process is also simple.

Step 5: Connect the wiring harness to the back of the new headlight.

Step 6: Secure the headlight by re-engaging the 2 retaining clips.
