Recently purchased an 07 Mercury Montego Premier for a secondary vehicle/work vehicle. Engine seems to be great, but there are various minor issues that just annoy me.
Driver's side window works, but not the auto function in either direction. Passenger side front window doesn't work at all, from it's own button nor the driver's side button. Is this a wiring issue or does it need a new motor? Or, how do you determine the issue?
The passenger side dome/interior light turns on and off when you wiggle the key/ignition. Again, wiring? How do you determine?
Cruise control works sometimes and doesn't work other times.
Bulb for fuel in instrument cluster goes dim, but illuminates fully with a smack on the dash.
Driver side heated seat isn't working. When you press the button the two little red lights illuminate (low/high heat indicator I assume), but they immediately go out when button is released. Passenger side works. Press the button once and both lights illuminate, press again for one light/low then again for off.
Traction control button will illuminate within the button and SOMTIMES a light within the instrument cluster. Why sometimes for the cluster light?
How does one determine the culprit for these issues?
