2001 4runner 4wd issues
Hi, first post on here so if there is already a thread that has the answers for my questions would be awesome if someone could point me there!
So my project 4runner 4wd issues: I had the blinking lights of death. I took out the transfers switches on the T-case and one was good and the other needed to be cleaned, which made it work. After cleaning them up and putting em back in place when I engage 4wd the blinking stops and the center Yellow light goes away while the other green lights stay lit. I press my button on the dash and the blinking of all the lights (center yellow comes back). Any suggestions on where I should look/mess with next? (also when I turn on the vehicle the blinking happens until I press the 4wd button on my shifter.) If pictures would help let me know, if you have any ideas much appreciated. thanks

If pushing the dash button makes all the lights blink again, you have either another position switch that is bad or your shift actuator isn’t turning.
you’ve addressed one bad position switch already, there are two more near the top on the passenger side of the t-case.
If it’s the actuator, usually what mucks them up is the contact traces inside that get corrode and no longer carry signal. What is happening is pushing the dash button signals the 4wd ecu you power up the actuator, the center lock position switch SHOULD see a change in position, when it doesn’t it blinks the lights to signal an error in the system.

I’m not sure if you have access from the top. I went from below and it turned out to be the contacts in my actuator. Swing passed the bank and get a roll of quarters for your swear jar. You’ll need them before it’s done.

You could gain a bit more room by dropping the transmission mount crossmember and allowing everything to sag a few inches. Let it rest on a jackstand.

Yes, those are the ones. That’s why I posted a pic of my 2001 transfer case.
I suggested earlier that you support the transmission/transfer case and then remove the crossmember that holds the transmission mount.. Once removed, use a floor jack to slowly lower the assembly a bit.

Yeah sorry i was looking for the one from that video since its something i can do right now. Was hoping to avoid doing something like this since I dont have the space atm to do much more than unscrew something "easy" and check out ie: the switches with the 27mm socket. thanks for the info and detailed pictures/suggestions on how to approach it, much appreciated.
