Does the wah work OK? If it does, then it shouldn't be too difficult to find the problem, if you have some tech experience, a multimeter, a soldering iron, solder, desoldering materials and an LED of your choice (if it's the LED that's shot, then you can replace it with a cooler one, like glowing blue!).
Here's what I would do:[list=1]
Start a thread on GuitarTricks Forum (I'm being serious). Oh, and maybe start one in Tech Talk ot try to get Lordathestrings' attention.
Open up the wah and be [u]very[/u] careful to remember where everything went.
Figure out which points the LED is soldered to.
If I had a multimeter I would use it to test the leads of the LED. Since I don't, I'd take a battery, two wires and hook them up to the LED.

If the LED didn't light up when I attached it directly to a battery:[list=1]
I'd crack open a cold one and get down to business by plugging in the soldering iron.
Enjoy a few sips while waiting for the iron to heat up.
Alright, time to get out the desoldering braid.
Desolder the LED.
Throw it out and curse Dunlop (although I haven't had my wah bug out on me yet, so they're still in my good books).
Insert the new LED (I'd get a cool blue one!).
Use my primitive soldering methods and affix the LED.
Close everything up.
Plug in - it's time to test this puppy out!
Open the whole thing up again when I realize I've done something wrong.
Finally fix it after multiple attempts.
Beam in utter joyfulness.

If the LED lit up when I attached it directly to a battery:[list=1]
I would panic, since my tech abilities would limit me to replacing the LED, not diagnosing and repairing the actual wah circuitry.
Frantically post on GuitarTricks demanding assistance.
Cry like a little baby.

... and that's all I have to say about that.
[U]ALL[/U] generalizations are [U]WRONG[/U]
