How do you replace the idle air motor on a 1997 mercury grand marquis and is it something an amateur can do?
Idle air controllers are held on by two screws on one side of the EGR block. Remove the two screws, discard and replace the gasket and reattach. Should take about 10 minutes.
I have a 1995 Mercury Grand Marquis and my mother has a 2003 and they both are the same, so yours probably is also. After you pull the trunk lining away so that you can see the metal, there are 3 large black plastic wing nuts that you unscrew. Once you remove those, the tail light section will come out from the front and then you can get to the bulbs to replace them.
