I put 5 oz of 91% iso rubbing alcohol in an old contact cleaning bottle (after I rinsed it with vinegar) and sprayed about 1/2 ounce at a time all over the 4wd shift selector while working it up, down, pushing it down, etc. Did the gear selector also.

My Limited model has the plastic sliding cover that moves up and down as the lever is moved...so the alcohol flows into/around it and down the shift lever shaft. It's not like the XLS that has a protective vinyl cape or bag over it.

Last fall 2015 I spilt about 6oz of coffee with honey and creamer on it and was traveling so had no way to properly clean up...I think that was making for sticky electrical connections.

So do this first before visually checking switches, lines, wires and cleaning them! Easy fix.

I have two 2001 XLS models and both of them apparently have a burned out center differential lock (CD) light. The 4wd drive selections work (2H-4H-4L) and all the wheel lites too but the CD box will never light up on 4wd Low.

It feels to be working but is there a way to confirm the Low lock is working?
