Hello,
I went to Lexus dealer and was about to buy the rear door switch but found out that the black piece that I needed from it has the word "AUTO" written on it, and the other switches on the master switch don't have it, it'll look odd, I don't like to have it on my master switch. so dropped the idea. on the other hand the dealer offered me a new master switch for $207.99
he said it his last one and want to sell it. will think of it after a visit to the wreck yard.
