Hi guys!
Got yet another Chevy, a -96 Tahoe. This one was given to me because it needed some care. Left to fix is the stoplight.
All three stoplights gave up on it, even the trailer stoplight is out of order. I want to check and/or replace the stoplight switch.
Where do I find it?
How do I remove it?

 

It is attached to the brake pedal arm. You have to remove the clip on the pin, slide the pin out and the switch will come out.

 

I'll try to crawl under there and look. I tried once but couldn't see anything, 'cause there's a bracket and the steering column obstructing the view.

 

It may be difficult. Make sure you have a good flashlight with you.

 

Yeah, I sometimes wish I had an eye on my indexfinger!

 

This is what the stoplight switch looks like. Does anybody know what color wire to measure on to see if the microswitch inside is OK?
I can se how the switch is attached, but there is no way I can pry it loose. I can also see the actuator on the brake pedal arm move the button on the microswitch.

Today I have been wrestling to try to reach the switch, to no avail! One way might be to remove the driver's seat (to make room for myself) and then remove the steering column bracket and THEN perhaps be able to remove the stoplight switch.
Or is there a better way?

 

Looks like it is clipped to a rod. If so, maybe you could unclip it to gain access to the wiring.

 

Yes it's clipped on, but it is also secured on a perpendicular axle with a spring clip . And I can't pry it off.
I now know that the orange wire is the lead and the white wire is supposed to deliver electricity to the brake lamps. But it doesn't. So the switch is defect and needs to be replaced.
My, oh why did they hide it so well?
Insert strong wording of your choice here. I did!
