You will have to use a 12V test light to make sure you are getting power to the socket. If you are not, check fuses (not likely) then make sure the inside of the socket is clean. A broken wire may also be the problem if not getting power. The test light will help you pinpoint exactly where along the wire you have lost power. I'd check where the wire goes from the liftgate to the cab first to see if you have a pinched wire.

The filaments likely broke in the newly replaced bulbs. Replace them with LED type replacements, if your local parts store does not carry them, they can be ordered from Digikey,

That should remedy the problem.

Cannot find the fuse for license plate lights. Checked the descriptions in fuse box but couldn't find anything. I checked the bulbs they look good.

Hello. There is no separate fuse for just the license plate lights. Those lights are part of the main exterior lighting circuit. If those are the only lights not functioning, you might nave a broken wire or bad ground.

Replacing license plate bulds on 1998 chev. blazer

Buyu yourself the Chilton's or Haynes Maintenance Repair Manual...ask the parts clerk for help on purchasing the correct bulb. Very easy task and that manual will also save you the time of not having to search out help on the easy stuff and you will find lots of helpful information in it.

If you are keeping this vehicle, I would definitely invest in one!!!! Less than $25 for the book...and saves you from future mechanic costs also for the simple things!!!!

Good luck!

1999 Blazer 4.3- license plate lamps inop and were changed with

I had similar problems but 10 times worse than your's. After a $800 bill and 3 months later my problems were back. So I took it on myself. Under the hood on the drivers side wheel well you will find the 'Fuse Relay Center'. There is an enormous amount of wires (harness) that enter it from under it, between the box and the wheel well. I found that over the years wires had bared themselves and were shorting out on the wheel well. I located the worn wires, simply applied electrical tape to worn area then applied approx. 1/4" thick spacers between the bottom of the box and the wheel well at the bolts. You can use a stack of washers if needed. Two years and 45000 miles later, no electrical problem exists...yet. This is a very simple and inexspensive fix.
