Awesome news, as my car didn't pass inspection due to "no brake lights." Im like, hmm, thats funny, seeing how i just drove out of my garage and seen the reflection of brake lights in the window behind me. The light in the window works though. This shouldn't be too hard to find no? Sometimes they work, sometimes they dont. Just gotta figure out whats touching. Figured I'd post as I can keep my buick buds in the loop on what's going on with the T-type. :icon_eyes:

You check the adjustment on the switch on the pedal? Should not be the switch if the rear window light works, tho.
So, the next most common problem is the white wire that runs from the switch on the pedal to the 11 connector terminal that is mounted on the steering column. Make sure this wire is firmly inserted into the connector on both sides and is making good connection.
When the wire comes out of the connector it goes up the column to the turn signal switch. Then there are a couple of feeds to the trunk to the brake lights...a yellow wire and a green wire.
Check the connectors at the column for these wires, and be sure the connector in the left corner of the trunk which can get dirty/corroded.
If it ain't a connection, then it may be the turn signal switch as Mark suggests below

If the 3rd brake light works consistently, and the lower 2 don't, there's a good chance the issue is in the turn signal switch.
I have had that happen on a TR and my Cadillac - lower lights stopped working, 3rd brake light still worked. I replaced the turn signal switch each time.

Thanks a bunch fellas. Im still at work. My mom looked for an excuse to drive the buick :D , so she offered to take the car to get it inspected for me. If it turns out to be the switch, would that be difficult to replace? I will inspect this evening step by step as stated Steve. Thanks you guys

Assuming it is the switch - it's a bit tough, but there's a lot of good info out there on replacing it.
The only symptom I am associating is that you said the 3rd brake light works consistently, and the lower brake lights work sporadically.

Gotcha. Well, I will have a solid diagnosis after work. Thanks a lot Supersix!!! Hopefully it's something simple. I hate hard work. Especially over something so silly.
-
Silly? Like fully operational brake lights?

Exactly. Like, if they not gone work, then don't work. But dont work when i leave the garage, and then not work when i get an inspection!! :013: It's embarassing to me to go get an inspection and my car not pass. Makes me look like I dont know whats required to pass. And the guy was an ass.

These are screen captures so not necessarily very good quality, but, maybe they are readable
-
Thanks for the schematics Steve. I can read the dialogue, but not so much the schematic. Shouldnt be too hard to troubleshoot though. Im about to check the white wire. And to confirm, the third brake light DOES work properly, but the bottom two don't. Keep you posted.
-
AND, my right turn signal is not working on the back light, but it works on the front. :icon_confused:
-
According to the schematic, and the dialogue, if the bulb is out, that could cause some of the functions to not operate properly?
-
Table C shows the troubleshootin g for the brake lites...not sure on the bulb....I spent more than half a day trying to sort out the turn signals on a car once only to finally find a single element bulb in a dual terminal socket :)
-
Damn. That sucks. I was only asking about the bulb due to the right turn signal not working in the back. The turn signal indicator also dont work in the car,but i can hear it. And it works in the front. im still lookin at this diagram though
-
i just didnt wanna have to remove this dash cluster if i didnt have to. only reason i was asking. thanks tho

Why would you not start by changing the bulb or troubleshootin g that?
-
Precisely...or use a meter or test light
-
You don't have to take the cluster out to fix this.. If it is the switch.
-
the turn and twist housing that the bulb plugs into seems to be cracked. I would have to remove the cluster in order to get to the back of it to remove/replace it. I'll tackle it though. I know I wouldnt have to remove the cluster for the switch. Thanks. Let you know what I find
-
Still don't understand why you have not replaced the bulb in the back of the car that is not working on the turn signal?
Are you now telling us that the turn signals work on the outside of the car and the problem is the indicator in the dash? And why do you care about that if you are trying to fix the brakes?

Im now saying that inside the car, the right turn signal bulb is out. Outside the car, the right turn signal works in the front, but not the back. Wasnt sure if this was due to my initial problem with the brake lights. But, now I know to just replace the flasher. :038:
-
And i care about that because the car wouldnt pass inspection with the signal not working outside the car(or inside for that matter)
-
so, why don't you replace the bulb and see what happens before you start talking about ripping the cluster out? Or swap bulbs side to side, or put your meter on the contacts of the socket to see if there is voltage pulsing there?
Just lost in your troubleshootin g technique, I guess....I will give up
-
ok
-
So, are you going to tell us what you fixed so the next guy can benefit from your experience?
Absolutely!! Turned out to be an intermittent connection going into the P7(white wire) as you guys had suggested. I cut the white wire on both connectors and just mated them with a spade end and a female end(kinda like a plug). Brake lights right up!
