Need to turn off my barke and abs light off that are on my dashboard for my 94 cadillac fleetwood brougham

without a scan tool and/or a DVOM you will be guessing as whats wrong

since you made no comments in tour post about physical brake issues then you are most likely dealing with a wheel speed sensor issue

however, you need the codes pulled to verify which sensors need replacing

On my 1999 Chey Lumina. My brake lights wont come on except for the one in the back window

I was having similar issues with my '95 Lumina. It started out with the passenger side brake light not working and the turn signal switch on the column acting funny.
Eventually, someone pulled-up next to me and told me that I had no rear lights at all.
It turned out to be the turn signal switch in the sterring column.
Hope this helps.
