GEAR SHIFTER WONT GET OUT OF PARK TO OTHER GEARS 1997grand marquis
There is an electrical brake light switch under the dash, at the top of the brake pedal, near the steering column. This brake light switch is wired in series with the gear shift lever, which means if one goes bad or has a problem, the other does too. If the brake light switch isn't working correctly, it will not allow the gear shift lever to be moved from the Park position. You first have to remove the plastic cover under the dash that covers the steering column (it will pop loose when pulled on and some are tougher than others to pull off but go back easily) to get to where you can see the brake light switch and the plug-in that plugs into it. Next move the seat all the way back to give you more room, and tilt the steering wheel all the way up out of the way. That switch could be bad or the two wires going to the plug-in could not be making good electrical contact. I had this to happen to my 1997 Mercury Grand Marquis and seen it happen to several others that I fixed. To test if it's the brake light switch, unplug the plug-in that has 2 wires going into it that is plugged into to the brake light switch (you will need a flash light, a flathead screw driver, and a pair of pliers to make this job easier). Take a 3 or 4 inch length of heavy solid wire, remove a small amount of the insulation from both ends of the 3 to 4 inch solid wire and bend it into a "U" shape to make a jumper wire out of it. Plug one uninsulated end of the "U" solid wire into one side of the plug-in with the 2 wires running to it that connects to the brake light switch on the brake pedal, then plug the other uninsulated end of the "U" shaped wire into the other opening of that same plug-in that has the 2 wire running into it. Your brake lights should come on and stay on, even though you are not touching the brake pedal, nor is your key in the on position, and your gear shift lever should move to any gear you want when you turn your key to the on position. Be advised, your brake lights will stay on as long as the jumper wire is stuck into the plug-in and will run your battery down if left that way. If what I have just explained happens, you have a faulty brake switch. If it does not happen, one of the wires going to the brake light switch plug-in may not be making a good connection or it may be grounded. To see if it's grounded check all of your fuses. Check the fuses under the dash and the fuses mounted on the fender under the hood. If you find a blown fuse, replace it. If it blows the fuse again, you have a ground and you will have to trace down where the wire is grounded and fix it. A volt meter set for 12 volts will aid in this when tracing a wire that is grounded. Then re-try all of this again after you have found any place the wire may have been grounded and you have fixed it. Most likely it's 1 of the 2 wires not making a good connection in the plug-in that plugs into the brake pedal switch. This seems to be a fault with the 1997 Mercury Grand Marquis. I've fixed this problem on 4 different Mercury's in the past. I don't know if this happens to other models of Mercury Grand Marquis or the Ford Crown Vic's. Hope this helps. Good luck.
I'm sorry meant to say the hose that let water out of trunk.
