You're not checking the ABS you're checking power to the 3rd brake light which is the light blue wire,I think that's what your doing. I just replaced the switch about 6 months ago and already forgot the process to get to it but it's not that bad. I think only the black panel comes off,don't forget the round speed nut type fastener at the very back of the panel by the firewall.

Forget all the ABS stuff.
Dollars to donuts it's the switch.
It has 2 sets of contacts, one for
the brake lites the other for the CHMSL.
Some people just jumper the 2 circuits together
on the brake lite part of the switch...

Speed nuts.....I hate speed nuts. Replace the front hood emblem not to long ago and learned about speed nuts.

That's where i was going to start last night, but couldn't figure out how to get the panel off. And ran out of light. I wanted to check the switch because I heard the connection comes loose or after 25 years it just went bye bye. Probably be good to replace it anyways....Thanks guys for the info and patience.

Fellas I'm at a total loss.....I got hush panel halfway off. I pulled the wire for foot well light, but couldn't get panel all way out. So I moved it to the side, could get access to the brake switch. But I have NEVER seen so much duct tape......its crazy. I don't know how to even go about removing the switch.....do you remove the wires going to it 1st? Is it held in by screws or how? This is becoming a big pain in the ***, I'm totally stuck and frustrated

The switch just pulls out of the bracket,once you get it out you will see how it's held in place. Putting it back in just push it in the hole.
