on my 89 gl wagon, it is auto and has the s/r push button 4WD. If i push it in, the lights on the dash come on, and all indications are that 4WD is engaged, but the button will not "click" and stay engaged. has anyone dealt w/ this? could it be a grimy, cruddy switch causing it not to go in far enough to "lock" on? or a faulty switch? i will probably pull it apart this weekend and see what is up, but it would help to go in with some foresight. thanks!

Could be cruddy or broken. My guess is it is broken. Hope I am wrong!!!

I fixed one of these for the neighbor 3 months ago... it most likely is the switch. Go to a PaP and grab a used one and you should be OK. It is a very easy and quick job to fix.

just gotta find some time to get my a** down to harry's then..

didn't even notice where you are from...yeah there are a few at Harry's...that is where i got the parts for the neighbors.

The one in my old XT was sticky and didnt click. I just cleaned all the grime off the switch (amazed to find it was orange not black) and gave it a shot of silicone lubricant spray. Worked the button a few times and it worked great - apologies if the switch you're referring to is a different design to that in an XT.
