Was having trouble with my back up lights going, and staying on, without wiggling the shifter, on my 1994 Camry LE V-6. I found the Toyota Nation Website, joined, (I'm a new member) did a search on the NSS, and found a post on removing, and cleaning the switch, complete with pics. A couple of hours time, and $2.50 for some dielectric grease, and success! I saved a couple of hundred bucks by doing it myself. All I can say is that this is a wealth of info for Toyota owners, and do it yourself wrenchers. Very happy!
