Running wires from kick panel to door?

Hello,

I am trying to run eight wires from the driver's kick panel area to the driver's door.  The vehicle is a 2002 Lincoln Navigator.  I need these wires run for the window module (up/down configuration).  The wire that I MUST access at the door is for the driver's "up" function, wired from the switch to the motor.  The rest, from studying the diagram, can be found at he kick panel.

Here is the problem:  Using the factory route--the rubber boot connecting the door and kick panel, I tried a fish tape and stiff wires from both directions (kick panel to door/door to kick panel) but cannot get through.  I can see and feel the fish tape going from the door up to and near the kick panel but it gets hung up somewhere just before the entry point.  Wrapping with tape and grease do not help.  From the kick panel, I cannot see the entry location.  Even with many panels and trim pieces removed, I can barely get my fingers on the entry point.  It is blocked by the parking brake mechanism (along with auto-relase parking brake components) and GEM module.

I am certain that somone has done this.  What is the trick?

Thanks,

JAMES.

Thanks for your response.  The factory route is indeed the one I am trying to use.  There is a rubber boot connecting the door and the kick panel.  Inside, there is a wireloom, tightly taped.  I am trying to route the fish tape along the wireloom inside the boot. 

The real trouble is that the entry point inside the kick panel is blocked by the parking brake mechanism and I can barely put a few fingers on it.  Removing the mechanism seems impractical.

Thanks for the many responses.  It would appear that the consensus is to pull out the boot to run the fish tape.

Question for those who have done it: is it difficult, after disconnecting the boot from the door or door jamb, to get the grommet portion back into the door/door jamb properly?

Thanks again!

JAMES.
