the problem can be that the gear wheel can be strip on one spot ,and if the gear is plastic,and because of the back being more heavy it puts more strain on the gear and some times one can rush and push the back by hand ,all this can cause the gear to
strip.

check for fuses. If some other defective stuff that you replaced broke the fuse then you may need to repower the system by replacing the fuse or a relay.

As for the air, do you mean no blower for both heat function and A/C function? An Owners Manual would show location for fuse and relay for blower. A web-search with term like "2004 Mercury Grand Marquis fuse panel or
blower relay location" could help.

Last, do not know if blower resistor relay was known good quality. This part is tempermental. Sometimes takes tap from broom or snowbrush handle to wake it up. Sad part is that after warranty there is little benefit from a used to new part. Should have been a National recall on this part.

put car in reverse, while rolling set parking break, this will adjust the shoes out, to hold it. Be sure not to set it too many times it will lock wheels down.

I would replace the clock spring rotating contact drum under the steering wheel for the restraint system warning light issues and check the operation of the headlight sensor when the lights will not go off, this is likely a sticking relay.

Nothing like guessing! There can only be 2 sources of issues. Lack of fuel, lack of air flow. Check fuel pressure and flow, check EGR and IAC.

front or rear wheel drive . always between the motor and transmission where the flywheel is .

According to my info, you don't have one. You do have a maf sensor and that should be in air intake.
