West of Seattle, not West Seattle
09 LX 185K, I had a minor service done at a semi local a/c evac and charge and oil change. Two days later I flew out of town for 10 days and came back to a snowed in Seattle. My battery died over the 10days ( dealer said battery was good). A couple days later I was looking to help someone out who was lightly stuck. I went to shift in 4LO and nothing. I regularly activate 4lo and center diff. I locked the center and pulled them back on the road. I followed with, driving 1/2 hr, disconnecting the battery for an hour, turning switch into 4lo and starting, and using a battery charger and starting after a couple hours.

Nothing I still have no 4 lo light, no click of the actuator. I haven't looked under the hood at fuses as the garage is full of other things. I am hoping there is fuse under the hood. But even during the start up process I get no 4 lo light as a test and don't remember if I am supposed to ? Edit look at the fuse and its good.

Thank you, at least that answers that question. I did check the fuse "4wd" #12 20A in the interior fuse box and its good. I guess I can pull the switch and check for power on both sides.

The switch that turns on 4LO has a little
Plastic piece on the side that hits
The button to engage 4lo. Mine had broken for some reason and wouldn’t do anything. Probably not your issue but worth checking out.
 
Before I tear to far into this where would the best place be to test and jumper? the 4 lo Switch?
