maybe use a temporary jumper wire from side to side to troubleshoot, then once you know which wire isn't working just run a new one?
I don't understand why you bought a "one touch" switch. The 2004 already has "one touch" down wired through the GEM.
On the master window switch pin #13 (WH/BK), confirm that when the switch is moved to the down position with the key on that you see +12 volts.
On pin #6 (TN/LB), confirm that you see +12 volts with the switch in the UP position. For both tests, make sure to use a known good ground.
With the key off, measure the resistance from the master window switch pin# 7 and 12 (BK) back to battery negative. Should be low. Post.
If all of the above measurements are good, then the switch is basically working. The problem is in the GEM or wiring.
It might be possible to bypass the GEM. However, I would never recommend doing this without a full set of wiring diagrams at your fingertips. If you do not have a set, I maybe able to help. PM if interested.
I am at a loss... I just can't imagine a busted wire in this car. How in the world would that happen? This car has been extremely well maintained, always garaged, never hacked on...how does a wire just break?
