Sometimes the headlights flick on and off while driving. Then when the car is turned off, there is a clicking noise in the driver side dashboard that continues until it drains the battery. Also, sometimes the door locks cycle open or closed whether the car is driving or off. This has happened multiple times and caused me to replace the battery, and still I have to jump the car from time to time. This has happened several times over the past few years, but only now have I found this site to report it to.

Splicing on almost all electrical systems had come apart. Affected were the radio, clock, windows, power seats, lights, door locks, trunk release inside car, low tire monitor warning light stayed on constantly, seat belt warning light stayed on, warning bell for key in ignition stayed on except when car was moving, dome light would not go off whenever you got out of car. Some of these problems were constant and some were intermittent. As a result of the locking problem, our vehicle was stolen, but thankfully found with no damage. With no help from our local ford dealer, I finally called the ford motor co. Complaint dept. And was told to get a diagnostic test run on it, which I did at another dealers, and that is when they found the wiring splicing problem. As a result of the electrical problems, it has blown the motors which control both the power seats. I have had the wiring fixed but not the motors replaced due to the expense involved. I feel like I have a real lemon on my hands as well as an unsafe vehicle.

I had checked the tire pressures prior to a road trip and found them at 38 psi. I reset the pressures to the spec of 33 psi. Shortly the tire monitor came on and signaled a low tire pressure. I rechecked and they were ok. During my trip the light would keep coming on and I tried to reset the system to no avail. On my return, the power door locks kept malfunctioning. The door key pad would work sometime for both the doors and trunk. The next time they might not. The door switches on both passengers and drivers side would work sometimes. With both the tire pressure system and the door locks acting up and creating a nuisance, I took the car to the ford dealership, two river ford in mount juliet, tn.. The found a shorted wire in the harness going to the drivers side module that coordinates most of the safety systems on the car. There was no fire in my case, however, there could have been. I did receive a bill for $272.30. My concern is that ford apparently does not accept any responsibility for what I consider a safety issue whether it was caused by poor system design on the harness layout or electrical current exceeding the wiring capabilities. Was it caused by excessive movement in the harness or was it current going through the wires as I tried to reset the pressure monitoring system 20-30 times. I am more then interested in knowing how many similar failures ford has had in the grand marquis and the ford crown vic.

Purchased an after market inside door handle from an ebay vendor: inside front drivers side door handle for a 1997 mercury grand marquis gs. The return spring on the original oem handle broke, but the original handle even though broken, still remained operational. I ordered and installed a replacement aftermarket door handle "depo" 330-500006-002 purchased from an ebay vendor. 10 days after installation, the replacement door handle failed and the drivers door could not be opened from the inside of the car making this a potential safety hazard had there been an emergency. Obviously the after market part was not properly tested before sale to the public.

This regards a 1997 mercury grand marquis, and a safety related issue that cannot be repaired by the car dealership. The driver side automatic/passive door lock, will not allow the driver side door to open at all. In the case of an emergency, there would no way to escape the vehicle. The ford/mercury dealership could not fix/repair the vehicle, and sent it back unrepaired. The driver's door is locked - and cannot be opened with the key, switch or remote control. They state that they have never seen this before, and the mercury national customer service, that I called today, stated that this has never been recorded in their database.
