That doesn't look too hard to do from what I've seen. How did it go for you?
Not bad. Pretty easy. Turn steering wheel so that top is 90* to the left (makes it easy to get to the screws in the switch assembly.
*Remove 3 screws from bottom of column cover. (T10? [can't remember] torque driver)
*Lower tilt, remove top cover.
*Raise tilt, remove tilt lever (1 screw, T20)
*Remove bottom cover.
*Remove 2 screws from switch housing (phillips head)
*Stick flat head between black housing where you removed the screws, and grey housing of the switch (It has a little nipple on it holding it in)
*Pull switch housing out & unplug it.
*Take inside and remove back of housing (3 torque screws, I think a T9, b/c a T10 was too big and I had to "make it work")
* Make sure you look at the positioning of all the little plastic slides so you can put them back like they go, take a pic if it helps.
*Pull them out (they aren't latched or anything) and clean them off.
*Clean area's where they slide.
*Clean mother board contact points on back of cover.
*Put it all back together.
Make sure the intermittent wiper "slide" is all the way down to the bottom when the switch is "off", it has teeth on the back side. You'll see when you look at it what I mean.
