 Assuming you've at least tried to turn it on with the anti-lock switch on 
the dash...

1) If the anti-lock lamp goes out after you start the car but comes back on 
after you start moving check the sensor positioning on all 4 wheels.

2) If the light stays on constantly remove the passengers carpet and the 
large black cover for the floorboard relay panel. In the top relay rack is a relay 
with a fuse, check the fuse, if its blown replace it, if it blows again 
replace the relay.

 No lamp involved with the cruise control.

 1st check the throttle positioning unit. Its a 2 inch round black vacuum 
device mounted under the drivers side distributor on the rear of the engine. It 
should have a vacuum hose attached and a rod going to the throttle. Make sure 
both are attached. If they are remove the hose and squeeze the positioning 
unit, cover the hose nipple with your finger and release the unit, it should stay 
compressed, if it doesnt replace it.

 2nd step, find a smooth deserted road and drive 35-40mph with the radio off, 
move the cruise switch from off to on and listen carefully for a faint click 
sound under the passengers side dash pad (beside the speaker grill) It may 
help to have a second person. There should only be a single click, if there are 
two or more clicks the column switch is probably bad. Depress the "set" button 
and listen for a single click. If you dont hear a click check the position of 
the brake pedal switch and make sure its fully depressed when the brake pedal 
is released. If it is and you hear no click or multiple clicks the problem is 
probably the column switch. If you hear the click but the cruise does nothing 
check the vacuum motor behind the hydraulic tank under the hood.

3rd step....pray you have it isolated by this time. If you havent you'll need 
to remove the dash pad to check signals at the control unit.

Good Luck
