Without knowing exactly what your problem is, seeing that you have a generation 2 Mark (97-98), I would suspect that your blen door is the problem. If it is, a couple dollar part and maybe $1500.00 labor to pull out the dash etc. to get at it.
In a 1998 Lincoln Mark VIII : In the Power Distribution Box ( which is " live " ) located in the engine compartment ( # 29 is a 40 amp maxi fuse for the Blower Motor Relay )
The first thing that you need to check is make sure that you have both power and ground going to the blower motor itself.........
Yes it will
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.
The cabin air filter in the 1998 Lincoln Mark is located behind the glove box. The glove box will need to be removed to get to the filter.

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.
Yes - but you will have to swap the intake manifolds and probably the exhaust manifolds.
