One problem related to horn assembly has been reported for the 1997 Mercury Mountaineer. The most recently reported issues are listed below.
When I use the cruise control and then turn it off I can't seem to push my gas pedal when you are driving the vehicle. I have to keep putting extreme pressure on the accelerator pedal until something breaks or pops and then it allows me to push the pedal. I keep having problems with smoke coming from on top of the steering column like something is burning when you are driving, now I have electrical problems to where my horn will not work anymore. I keep having problems with the front frame of the SUV. The frame sounds and feels like it is going to fall apart and it doesn't matter if you are driving or stationary. The mechanic says it is the sway bar that is causing that problem. I have been calling Ford about it and they keep saying there is no recall on my vehicle.
