I always found it easier to unbolt the AC compressor to get to the plugs on the passenger side and remove the intercooler and intercooler tubes to get to the driver side. Doing this takes a little extra time up front, and unless you have the Teflon gaskets you will have to reseal everything with RTV and let that cure, but once those are out of the way, all of the plugs are easily seen and accessed from above, and at that point changing all the plugs shouldn't take more than an hour.
Also on the window motor, if it is making noise but just doesn't move the window up, that is an easy fix. Once the motor is out, remove the 3 torx screws that hold the plate around the gear, and out will come the gear, and a bunch of broken up plastic. Clean everything up, and find either some nuts or ball bearings that are the right size to fit in there, and put everything back together and it should never give you a problem again.
