in the rear facia, under the trunk lid there is 9 bolts holding the facia on. You must remove the nuts and pull the facia out and right above the license is the two bulbs 194. replace the bulbs and put the facia back on and you are on your way.
check your fuses first, then check your bulbs and then your relay.
you can see the plugs on the back of the light. lift the trunk and look past the license plate . the twist out . righty tighty lefty lousy . pull them out. its tight but they come out. use needle nose pliars, but be gentle.
It is one big peice that must be removed. If you open the trunk, look on the inside of the lid behind the license plate, and you will find a few nuts that once removed, will allow you to remove the entire rear facia panel that the license plate bolts to and which houses the "PONTIAC" lights.
You need to remove the liner on the trunk lid. That will give you access to the license plate lights housing. Remove the sockets by twisting 1/4 turn and replace bulbs. Size for bulbs are 2825
I'm guessing that all of the light bulbs have been checked and are good. It's possible that you need to replace the flasher.
I can't be 100 % sure as I'm not real familiar with your model, but my earlier Sunfire's bulbs are accessed from inside the trunk, You'll have to pull the carpet away from the body, then twist out the bulb holders.
Check the bulbs, check the fuse then check the switch.
Low beam bulb burnt out? Replace bulb. Bulbs OK? If the dimmer switch is also the turn signal/cruise/headlight on and off switch, you probably have to replace the entire switch.
You have to remove the dashboard, then remove the instrument cluster. On the back of the cluster, you'll find that you can unscrew the bulbs from the back and replace them. I've done it myself on my own 99 Sunfire --- CanadianCynosure
To replace the brake light on a 2000 Pontiac Montana open the trunk to reveal the housing units. Find the lights and pull the bulbs out. Replace the units.
Epic Failure.
