Traction control light won't go off on my 02 grand

SOURCE: 2001 Mercury Grand Marquis brake and ABS dash lights on and off

The red brake light is the key here. That usually indicateds a hydraulic problem. Check you fluid level in master cylinder and see if it is low. Also the level indicator sensor there in the master cylinder maybe sticking or corrioded. If ABS sees the red brake light it will shut off and turn on the ABS light,also traction control would be disabled as well.

Sounds like you have a bad wheel speed sensor. You need to have it scanned. Since it's been sitting, it might just be a bad connection to one of the speed sensors.

Have seen this problem before. You need to look under dash at brake pedal and find a blue switch with plunger contacting pedal, disconnect connector and jump with a peice of wire and drive to see if cruise works and if it does replace deactivation switch this should get you going.
