I have not expierenced a failure to my car (except that the drive train had to be replaced before 50,000 miles). I am sending this info. Because I discovered that there had been a recall(NHTSA campaign #99v124000). I want to find a dealer in or near my area to replace and install a "new speed control deactivation switch and connector shell) my car was bought from a used car auto sales place.,not an actual mercury dealer. Can you please advise me on how to proceed in having this defect to my car repaired?
Consumer was in between two trucks and her air bag involuntarily inflated, consumer caught on fire,lost control,ran into passing vehicle at 12:00 position. Tt
Brakes failed twice due to excessive wear of front brake rotors/pads/calipers, once resulting in an accident/injury, also pulsate.
Consumer drove home, parked the vehicle under the carport, went into the house,then heard an explosion. Consumer looked out of the door and discovered a fire coming from the left wheel well. The fire department responded, extinguished the fire, and the vehicle was totaled. This vehicle not included in the cruise NHTSA recall 99v124000. Consumer never received recall regarding cruise control. Cruise control failed just as stated in recall.
I have pictures of the fuel pump I took out of my 1992 mercury grand marquis. The car had coughed to a stop and I suspected the fuel pump. There was no pressure in the fuel rail so I pulled the pump out of the tank. I checked the pump with a battery and it ran fine. Then I started looking at the fuses and found the 20a pump fuse blown. Obviously there was a short somewhere. As you can see by pic 2 the short occurred when the "hot" wire insulation was worn through on the float bracket.
