No dash lights, flashers wont turn off and car will not shift gears

Is it only the gauges or the all the instruments and heater controls? The first place I'd look at will be the dimmer switch. Normally the instrument lighting shares the same circuit as the parking/valet lights.

Since you only mentioned drive, I'm going to presume you meant you can't shift into any gear, Is this correct? Normally, I would say this isn't an electrical issue, it's mechanical, either something in the shift column or the shift linkage is broken or come loose so I browsed the fuses in my owner's manual and you can check these fuses: fuse #8 (10A) - Shift Lock, Speed Control, fuse #14 (7.5A) - Transmission Control Switch, fuse #10 (20A) - Brake Pedal Position, Brake Pressure Switch. If you can't shift out of Park, turn key just enough to unlock steering wheel (not turn on dash lights) and see if shift lever moves. If so, then shift into Neutral and start car.

This problem sounds like you dislodged the switch on the brake pedal lever. You need the signal to unlock the vehicle from Park. You will probably find that the Brake lights do not work when you press the brake pedal.

Now if the switch is good, you probably broke the fuse feeding power to the switch. You can get a wiring diagram online by running a Websearch or going to Autozone.com and registering your car. This site has a HELP section at the bottom of the page and you would need to toggle between free and pay info.

It can be as simple as a blown fuse. Do the brake lights work? The brake light switch turns on a soioid that ets you take it out of park. Theres a cable on colullum shifted cars that can break or come off but the brake light swich failing or even the high mount brake light bulbs being burnt out ( depending on what country the car was built for ) the don't what you driving if your brake lights don't work.

put your foot on the brake ,if your brake lights are out the wont wont shift out of park you need a brake switch

I believe that this is what you are looking for.....

check to see if the brake lights come on it may be a problem with a brake switch under the dash not letting the shift lock release. there may be a seperate switch just for it so check and see it there is two switches touching the brake pedal lever if the brake lights come on.

there a little switch on the shifter to stop it from going into gear with out the brake on .eather theres no power or switch is bad. it under the dash at the shifter .good luck

does the high mount stop lamp work? Try turning the emergency flashers on and off a couple times

no disrespect but....
Check the book and make sure you are using the proper bulbs on all sides. (3957 looks just like 3956 but wont work right)
