What have you checked so far? Are you stepping on the brake pedal first before you try to shift into a gear selection? Are the rear brake-lights working?
Ok so you need to go further and check for blown fuses. If one or more is blown and you replace them do they blow out, is it fine, or did you find nothing wrong?
If the fuses are fine then you may have a bad brake switch, relay, or wiring. Please let me know what you find and how it is going.
Well you are doing good so far. Now you need to try finding the source (the short). If you have or can buy/borrow a short finder it will make finding this short fast and easy. If not, you need to look at as much as you can. Inspect the wiring, the bulbs (even look at the filaments) and the part number if they were replaced recently (could be the bulb), I don't know the condition of the car but if it has body damage you may want to look at the affected area for pinch wiring.
Looking for shorted wiring can be long and frustrating. But you now know the circuits that are being affected so that does help narrow it down.
If the brake-light switch and the wiring checks out it is hiding its self. You will have to make a choose whether to continue looking or to sent it to the dealer. If you choose to continue then you may want to look under the carpet. I can say that with a short finder the mechanic will probably find it in less then an hour. I wish I could help more but with a short you know what I'm saying. Good luck and stay in touch, I'd like to know how you made out and where the short ended up being.

After checking, none of the rear lights are working.

I replaced the #31 and #32 fuses, both blown. The # 31 fuse blows when the lights get turned on. I disconnected the balast from the rear center light, replaced the #31 fuse then turned the lights on, the fuse did not blow and the turn signals now work. However, when I step on the brake the #32 fuse blows. I am picking up a brake switch tomorrow morning since the shifter still does not shift into a drive gear. I look forward to your recommendations. Thank you.
I replaced the brake switch today and it solved the gear shifter problem and most of the rear light inop problem. When I reconnected the center rear light
(neon I think)balast both the #31 and #32 fuses blew again. I disconnected the the balast and replaced the fuses and no issues except for the center rear light not working. At least I can now drive the Mark VIII with brake lights and the outer tail lights. My question now is what can I do to repair the center neon light?
Can I just replace the balast or do I have to find a complete unit? Thank very much.
