Many vehicles in that age group were fitted with a safety INTERLOCK which was designed to prevent a driver from taking the transmission selector lever out of "Park" UNLESS their foot was on, and holding, the brake pedal FIRMLY depressed.
This was to prevent the vehicle suddenly "lurching" upon being shifted into a "moving" position.
The interlock safety function was accomplished by using the brake light electrical signal to a type of solenoid locking mechanism on the gear shift selector, or in the transmission.
I suspect that you have what is commonly called an "open circuit condition" in the brake light / safety interlock circuit, and that is what is preventing you from taking the shift lever out of the Park position.
Therefore, once you find and correct the open circuit issue, then the shift lever will become responsive again.
Obviously there are probably several possible causes for the open circuit, and following are a few that come to my mind at the moment.
Again I caution that, as I am not specifically familiar with your vehicle, there could be other causes I haven't listed. Good luck.
Usually, there is a dimmer switch within the car to make the dashboard lights come on. In most cars, the switch located within the dashboard. If you are having a problem with your lights, a fuse can possibly be blown. Be sure to check the fuse box to rule out any issues.
maybe fuse or broken wire between lights and relay
If the fuses and bulbs are okay I would blame the signal switch assembly. They call it a multi-function switch these days.
change the headlight switch !
Have you checked the drl relay?
fuse relay wiring switch
It isn't, although the question raises some issues about isolation, etc.
on what vehicle ? ford Chevy crosley fiat yogo ? there could be more than one switch usually the reverse light switch is located on the trans
I had a similar problem with my S70 and discovered the headlight switch was defective. The switch had actually begun to separate causing the contacts for the tail lights not to make contact. Try having someone observe the tail lights while you push on the headlight switch. If the tail lights begin to work, replace the headlight switch.
Have an electrician check the wiring that goes to the brake lights in the trunk of the car.
It shouldnt. The cruise control senses by the switch on the pedal not by the lights.
you have a short in the wires for your dash and lights So what do I do to fix it?
