93' Abs Not Working!

I have a 93' LeSabre and the ABS does not work. The ABS light is not on and no codes. It just does not work. Hit the brakes and they lock! Checked fuses and they are good.Car is giving me nothing, any ideas??

Start with the relay and both abs fuses, see if they are in place or blown.

In case you need locations of ABS fuse & relays:uhoh:

Checked those and still nothing. If the ABS computer is dead will the light come on? Can I take it out and have it tested? Where? Also I have been looking at parts online and they have three different master cylinders for the car, which one should it have? The 8'' master cylinder is on it now.

It is under the l/s of the dash remove the lower cover to access looks like a small pcm. BTW nices pics, HotZ28
