Probably the coolest hack we’ve tried is the green lights over the AC controls. All Vanagon owners know there are no lights for the AC controls. We got some LEDs from Radio Shack and my brother somehow managed to wire them in.
We removed the controls from the dash, drilled some holes and inserted the LEDs. The picture isn’t so good but believe me, it works very well.
Now when we drive at night the A/C controls are illumniated and it looks like it should’ve always been that way.
I tried to take a better picture without the flash that would show the illuminated lights, but it didn’t really work. Sorry.
UPDATE: Here is a better picture…
