Customer Question

1991 Cadillac Deville needed a jump start...put it in N to push back to allow a car in front to jump start and then put it back in PARK. Cable were hooked up correctly but one of the cables slipped on the dead battery and the handles touched...sparking and a small flane appeared before we quickly disconnected it...now car wont shift out of PARK...even after fully charging the battery. Car runs great but wont move as it wont come out of PARK.

You probably have a blown fuse somewhere, if all the fuses are good then the shift solenoid may have failed. Keep me updated on lgihts, thanks.

PLEASE HELP

Check the 20 amp fuse in location 19 of the interior fuse box. Let me know if it is blown, thanks.

Customer: replied 11 months ago.
ok....I checked it and its good
Customer: replied 11 months ago.
I checked the fuse in 19 and its good....what else should I check?
Customer: replied 11 months ago.
I checked every fuse in the fuse box to the lower left of the steering wheel....none are blown
Expert:  Dan replied 11 months ago.

Next step is to access the shift lock solenoid and check black wire for ground and green/white wire for power when brakes are pressed. Let me know, thanks.
