The button that is used to turn the heated seat to low/high doesn't lite up anymore. Is that something easy to fix? I have an '05 and it'* only the passenger side button. This is NOT related to seat heating element-my heated seats work fine it'* just the button itself that is suppose to be illuminated but isn't/

In my 2001, the switch housing unsnaps. It is kind of a pain but with a really small screwdriver, you can pry the plastic off the two latches that snap together. I remember there being a way to disassemble the top or the bottom of the switch. I think you want to do the bottom, but don't remember for sure. When you get the housing apart, there is a PC board with two lights on it. The lights have an amber prophylactic kinda thing that will slip off.

I used small light bulbs I got from Radio Shack. They are very slightly dimmer than stock though (you can barely tell). The part number is 272-1092 and they come in packs of two.

Anyway, the lightbulbs solder onto the PC board and there is a small plastic shroud around the base to keep them pointed straight. The Radio Shack bulbs won't have this plastic piece so you'll have to reuse them.

There was another post a week or so ago saying the lights are not replaceable, so the 2001 may be different than yours.
