Stop Lights

I have a 1994 Buick Regal Custom.
I have been having problems with the stop lights. The light in the window comes on without problems. The lower lights will not come on when you step on the brake. I have replaced the brake light switch. I still have the same problem.
Has anybody had this same problem? Would it be possible to get a wiring diagram of the brake light circuit?
Thanks

You may have a problem with the turn signal switch in the steering column. If it goes bad, it will effect your brake lights. Ever notice slight smoke coming out the top of the steering column? Check for power to the brake switch. I hope someone here will send you a wiring diagram.
Good Luck.

Thank you pcv for your reply.
I did find the problem and it is the turn signal switch.
Thnks again!
