I have trouble with the lamp monitor, it says Brake Lamp but I´m not able to find any not working brakebulbs.
I´ve changed the two at each side and the high mount brake bulb, cleaning the connectors at the same time without getting any change.
One thing I´ve noticed is that if I keep the brakpedal down the monitor toggles the waring message, maybe it´* right but I don´t know.

look at the 2 license plate bulbs, if these are out it will set of the monitor

Will those set the brake light warning?
Missed to say that it is a 1992 SSEi in the first post.

He just said it would. And its easy to check...

He said it would set the monitor, but not wich error...
Enough with that, I´ve just checked the licensplate bulbs and those work just like they should.

then you are going to have to pull all the bulbs, clean all the contactsand sockets, and reassemble with dielectric grease on the connections. You may have one arching, causing an abnormal amperage situtation, causing the monitor to go off.

I´ve already changed all the bulbs and cleaned sockets/connectors.
Right now I´m thinking about if I might have bulbs with wrong wattage...what is the right bulbs for stoplight?

The license plate bulbs will set a "tail lamp" warning. Brake light warning is specifically the elements in the bulbs for brake illumination only. Being that some bulbs have two filaments, it can be fun.

Besides cleaning and replacing all bulbs, also look around for any pinched/rubbed wiring. With it being in the trunk, it is possible packages can slide and upset the wiring. Overall the monitor is fairly sensitive.

What a coincidence… I have a 92 SSEI and had an intermittent problem with my lamp monitor going off and showing the center mounted brake light being out. The bulb looked fine. I hooked up my volt/ohm meter to the bulb and it showed continuity. I re-seated the bulb and it would work. After driving around, the monitor would show that bulb as being out again.

I took the socket out today and looked closely at the metal contacts on the inside of the socket. The center metal strip which makes contact with the base of the bulb was fine. The metal strip on the side of the socket which makes contact with the metal side of the bulb was cracked (due to metal fatigue). That second metal strip is bent slightly to make physical contact with the side of the bulb. Because this second strip was cracked and not making good contact with the bulb, it would trip the lamp monitor.

My local Pontiac parts department wanted $10 for a new socket if they had it in stock. They said if I ordered it today, it would arrive the next day. Instead, I went to a local salvage yard and got a used part for $5.00. The socket is probably the same for any GM full size models from 92-99.

Being in Sweden, your only option may be your local dealer…

Good luck!
