problem #3

Mountaineer LX

  • Automatic transmission
  • 91,000 miles


The door locks cycle on and off, often the alarm is also alerting. This happens every two to three days after attempting a system reset, by disconnecting the battery. When the system is malfunctioning at its' worst the door lock switch reverses polarity on for off and visa / versa. I suspect it is a failing fuse and /or relay ad/or diode. The relay /diode theory matches the reverse polarity issue. Can any one identify which fuse/relay/diode serves alarm door lock circuit. Ford was helpful and these circuits are not identified in the owners manual.

Mountaineer LL 4.6L Efi V8

  • Automatic transmission

This problem started out of the blue, in the middle of the night! I thought someone had tried to break into my car. Horn alarm blowing & interior & exterior lights flashing on and off. It happened 3 times that night. A day or 2 later it started locking and unlocking itself, interior lights, dinging sound and "Door Ajar" warning light turns on & off continuously whenever I drive anywhere. Now I can't lock my car without the alarm going off for absolutely no reason.

I can not set the alarm on my car because it keeps going off. Even when the car is in park the alarm goes off. I live in an apartment complex and my apartment is in the back.One night I was really embarassed because the police knocked on my door at 5 a.m. in the morning telling me that my alarm had been going off since 2 a.m. and the neighbors were complaining. I feel that the Mercury company should do something about these problems that people are having with their cars.
