Your GMC vehicle's headlights are a crucial part of its safety system. They're also an important indicator of how your car looks. So, it's important that you keep them in good shape. Over time, you may notice that the GMC car headlights aren't working as well as they used to. Maybe one is dimmer than the other, or maybe neither works anymore. Fortunately for you and your driving safety, changing out these bulbs is relatively easy if you know what to do!
GMC vehicles have a number of different headlight styles and options, so it's important to determine exactly which type you have before purchasing new headlights. You will need to remove the old headlights in order to change their position and replace them with new ones. This process varies depending on whether or not your vehicle has halogen bulbs or xenon bulbs, but all of these instructions will require tools such as a set of wrenches, screwdrivers, and pliers.
Park The Car And Turn Off The Engine
Before you start, park the car on a flat surface and ensure the engine is completely stopped. Turn off all lights, turn on your parking brake, and ensure that the area is well-lit by street lights or another light source. You'll need to be able to see clearly while working with your headlights, so it's important to complete this step before attempting any work.
Take Out The Old Bulb
The first thing you need to do is remove the old bulb. Open up your hood and locate the headlight assembly (it's a big black plastic box with four bulbs on it). First, use a screwdriver or pliers to pry off the rubber covers over each headlight. Next, remove the screws holding it and use a socket wrench (if necessary) to get rid of that pesky metal headlight guard. If you're having trouble with this step, try using WD-40 on the screws before trying again-it'll make things much smoother! Once that's done, simply unscrew each bulb from its housing and pull it out by hand.
Use The New Bulb To Replace The Old One
The next step is to replace the old bulb with a new one. To do this, place the new bulb in the socket and check that it turns on by pressing the "High Beams" button on your steering wheel. If you've done everything correctly, both headlights should come on at once and stay on for about 10 seconds after you release the button. If it does not light up, there may be a problem with the wiring or connections inside your headlight assembly. You can try another bulb or call a mechanic for assistance if this happens. If everything checks out, reinstall your headlight assembly by first replacing all of its mounting bolts and then tightening them in sequence from left to right until they're snug but not overly tight (which could cause damage).
