For the past three days our 4wd will not disengage. It is not so bad on snow, but driving with 4wd on dry pavement is a pain..... Plus, the 4wd indicator on the dash blinks constantly.
The problem on our 01 4runner was a faulty transfer case indicator switch. It is either a transfer case switch or indicator sensor, I forget which. Either way it is one of two switches on the transfer case actuator, CLOSEST to the front of the vehicle. A 27 mm socket fits on the switch. Remove the old, tighten a new one on there and boom....our push button 4wd works again. I have driven the vehicle around and all seems normal again. I'll paste a photo of the old switch below.
If you are stuck in 4wd and can't replace the switch, you can disconnect it and fool the system. I did not bother doing this and just swapped out the switch. Here is a more complete thread from Yotatech, 4WD won't disengage on 99 4Runner LTD - YotaTech Forums
For those driving trucks older than 2001, this may not be your fix. Apparently the switches differ and you will want to read the thread above.
The Toyota part number for my fix is 84222-12010, it was about $60 from my dealer and 20 minutes of my labor.
