Do it yourself, change the front parking light assembly on your Chevy S10 Blazer, produced between the years 1998 and 2005. This replacement doesn’t require tools, maybe you’ll need a pair of pliers if the headlight’s holding tabs are stuck, worn or rusty. The repair is quite simple and you can do it in about 20 minutes.
First of all, open the hood of your car and go to the parking light that needs replacement. In order to get access to it, you will first need to remove the headlight assembly above. You can do that very easily by removing the metal tabs that hold it, as seen in the picture below. You can do it by hand or using a pair of pliers, if the tabs are stuck. After you release the headlight, you will have to disconnect the three harnesses behind it and remove it completely from the body of the car.
Detaching your headlight will give you better access to the parking light assembly. If you only look to service the light bulb, you can reach it now and replace it without problems. But if you need to replace the whole assembly, you will have to squeeze the two plastic tabs that hold it (see one of them in the image below).
Make the required repairs and replacement and install everything back, reversing the process presented above. This is all you have to do, if you need to change by yourself the front parking light assembly on Chevy S10 Blazer, made between the years 1998 and 2005.
