92 LeSabre Custom - Third Brake Light

Does anyone know how to replace the third brake light - the one in the back window? Owners Guide refers to it as "High Level Stop Light" and references the replacement bulb number but offers no instructions for replacing it.

Reaching in from the trunk, I feel a plastic wired "plug" that goes into the metal bulge directly under the light, but it won't come loose and I don't want to force it. I doubt I'd get ticketed for this but I love the car and want to keep it in ship-shape. Any advice?

PS - As soon as I drove this car I knew I was born to drive a Buick!//

Turn the bulb socket 1/4 turn and it should come out.

Thanks! Got the bulb out and it's fine, however no power to the socket. Horn also doesn't work and multi-meter shows no power to that either. Engine comparment light is unplugged (since car was purchased) and the little dangling socket looks green/corroded inside. Could all these be related? All on same circuit? Bad fuse maybe?

Check fuse #13 it provides power to the stoplight switch and from there to the third brake light. Did you have someone depress the brake when you tested for power? The horn & underhood light have nothing to do with the third brake light.

The bulb socket may also be bad. I you constanty wiggled and pulled on it to get it out you may have damaged it. I had to replace mine. New light and it still didn't come on. Off to the junkyard I went and got a new one and the light started working again.

The socket looks fine and it wasn't working with the good bulb in there even before I removed it, so I'm more inclined to believe it's an electrical and/or fuse problem.

Temps here have been around 0 all week :cya: - I'll check it out when it warms up this weekend. Thanks

The socket can look fine and be messed up. Mine looked like nothing was wrong with it but the connections inside the socket were bad. If you wiggled it would make contact and the light would work for a little bit and lose connection again. But I have the the lamp moniter control. Don't know if you do, so I could moniter mine real time.

Lamp monitor control?! I don't know anything about that... I have the poor-man's lamp monitor control - I back my car into a space in front of the 7/11 and check the window reflection to see if all my rear lights work! :smile:

That provided my laugh for the day. Great comment. Guess it would depend on what part of town you're in on that too.
