Just did this tonite.. unhook battery, remove the glove box, and door..remove the center of the dasy that covers the speedo etc.. remove the rt AC vent so you can see down on the rt side..remove the rt kick panel.. i removed the ac controller just to get it out of the way.. on the rt side cowl there is a vaccum motor you must disconnect. then on the rt side you will see the vent motor with 6 screws around it.. you then remove that assembly..with this removed you will see the motor unplug wire and remove the one screw holding the assembly.. then reach in and turn the motor counter clockwise...and gently remove the blower assembly.. reverse the process to install new motor
Remove the wiring harness from the back of your 1986 Lincoln air conditioning blower motor. Remove the blower motor retaining bolts. Remove the fan on the front of the blower motor. Reverse the process to install the new blower motor.

Passenger side under the dash. If the blower isn't working check that the wire isn't corroded off first, common for this to happen.
The first thing that you need to check is make sure that you have both power and ground going to the blower motor itself.........
I had the same problem with my 98. My mechanic found a loose wire at the blower motor connection.

You need to take a 12 Volt circuit tester and trace back from the motor; you must not be getting current. Test the switch and the ground to the motor also. Mark
