Two problems related to wiring have been reported for the 1999 Mercury Mountaineer. The most recently reported issues are listed below.
The display on the premium factory radio does not function properly. Illuminated digits of the display panel may work intermittently or not work at all. All other functions of the radio seem to work. My research indicates that this has been a problem on radios installed in various Ford motor company products of the 1997-2001 model year range. Ford motor company should make a no-charge repair on these radios.
Airbag light comes on, flashes goes off, comes back on. Dealer recognizes problem and has designed a robust electrical harness replacement but refuses to cover costs. This re-desing of the electrical system for the proper functioning of the airbag restraint systems was first recognized by the manufacturer in 1999, the date of the vehicle. The NHTSA bulletin number is sb610933. Please help!!! this is a serious safety issue and concern for not only myself but the saftey of my children.
