The vehicle suddenly had no brake lights or tail lights, then, it had brake lights and tail lights, then, the vehicle would not start, despite having a new battery. After much investigation and work, our certified mechanic feels that the lighting module is shorting out, thus, draining the battery. The vehicle was stationary, in motion on a city street and on a highway, turning, essentially all aspects of usage, when these issues occurred.

Problems with my wife's 2002 mercury grand marquis ls not cranking at odd times. I have cranked up the car, and driven it into the garage, then go back out a couple minute later - 15-30 minutes - and the car would not crank. The last time I pulled the car into the garage one evening and when my wife went to go to work the next morning it would not crank. The dealer's service department can not find a problem. However, the left turn signal went out about a year ago, requiring a module be replaced. After that we noticed the foot pedal adjustment diid not work and a loose connection was found to be the problem. The starting problems did not start until after the turn signal module was replaced. I have found other incidents of problems with the ignition switch for this model mercury.

97 mercury marquis gs, it has 91k mi on it. The intake manifold failed unexpectedly with a crack in the plastic coolant crossover. The coolant sprayed all over inside of engine compartment. It was the weekend I was on a rural highway in the sticks with my two kids ages 4 & 6 in the car somewhere between boston & the university of nh. Not wanting to become stranded in sub zero degree weather in the middle of no where, I managed to crawl it into the driveway of a local mechanic where it died & would not start, the motor was super hot! The mechanic added coolant managed to get the engine turn over after sitting for the weekend & called to tell me the plastic intake manifold was cracked & that is was not covered under recall by ford. It cost me over $1200 for the expenses incurred as a result(parts & labor, hotel & rental car expenses). The engine miraculously has been running fine for close to a year now with a newly factory redesigned (aluminum coolant crossover) ford intake manifold.
