1998 Grand AM Brake/ABS problem

I have a 1998 Grand Am with an ABS and Brake light on the dash that will not go out. Brakes have been bled, and fluid level is good. ABS does not work, brakes work fine. Pads and shoes are good. Battery was disconnected for a while to clear codes. Disconnected all wheel sensors, sensors on the ABS unit, and on the master cylinder. Nothing has changed. Autozone told me to jumper the wire going to the master cylinder to see if the light goes out, and if not, jump the one on the emergency brake cable. It only has one wire. Niether idea worked. They also said put a meter on each wheel cylinder and spin the wheel to see if I get voltage. Do these ideas sound right? Any other suggestions? I am at a loss here. Thanks

You will save yourself a lot of time and stress by just having the ABS scanned for codes. Otherwise, you are just shooting in the dark.

Ian is correct.The reason the warning lights are on and the Anti-loc isnt operative is that the system has detected a fault and disabled the Anti-loc sys- tem ,returing it to what is called foundation brakes, or brakes that SHOULD work normally without the anti-loc feature. The best bet is to go to a good repair shop and let them scan it to find the problem. They will probably charge you for a scan test,but otherwise you will just be wasting time trying to find the problem.A lot of the time it is due to a faulty wheel sensor.

It is often cheaper to have brakes fixed than to pay for a funeral ;)
