has the 4.2l and eas fully operational
ok so far the problems are
rearview mirror not dim, but maplights work
sunroof not work
interior lights, (courtesy light)
drivers seat no move(power at 30a fuse under driverseat, none at switch)
cruise
power mirrors
stereo
emergency flashers
and now the heater(when i first got it the heater worked, when i put on the high beams it would kick fan to high
and i believe the water pump is gone(leaking, could it be just the seal)
abs light and traction control lights on in dash(sometimes they are both off, but usually on)
hi/lo shifter not shift from hi
was told everything was working including the sunroof
can anybody help with any of these issues,
all help is greatly appreciated

ok it seems after the ignition switch the brown power wire doesn't have 12volts in a lot of places, is there a large joint section somewhere in the harness i should check opcorn: or a relay maybe?
