A guy down the block has a 90 Lincoln Continental ( FWD ). He's had an off an on problem for about 6 months with the brake shift interlock not working where he could not get the car out of park.
It took some hard braking & lever jiggling to get it to finally shift - until last week. The car decided to remain in park. Had the car towed to a local mechanic.
Mechanic determined it was a cracked wire in the trunk going to the left brake light bulb that caused the shift interlock to not work.
He repaired the wire & all is fine. He told my neighbor if it happens again try turning the hazard flashers on when you shift - this apparently completes the circuit and the shift interlock would function.
Just thought I'd pass this story along.
