4wd light wont stop blinking

[Frost29]

Hi, another member of the club here:
When today I pushed the 4wd button on neutral the light with the 4 wheels and yellow in the middle only started blinking and the 4x4 did not even engage , now that light won't stop blinking. I have tried all the tricks I read on the book, driving straight ahead, accelarating, driving in reverse, but the light just won't go off.
If I push the 4wd button again, is just doesn't do anything and it would just keep blinking. I don't know what else to do. Any suggestions folks? Thanks.

After reading a lot of posts, it looks like my problem is the front diff sensor. I am willing to change it, but I only see part number for 99's. Does anybody know the part number for a 2001? Is it one or two diff sensor? And if, by any chance have pics or instructions of how to change it? Thanks!

Update: I got the part number:84222-12010, I just would need instructions of pictures how to change it. Thanks.

Ok, I just came back from the Toyota dealer, they did the diagnostic and told me my problem is that 4wd actuator is stuck and needs to be replaced. Cost is : $800 for labors and parts. I 've been reading a lot of post here and still think that is more likely one of the tcase or differential sensor.
I read the thread: 2001 Limited 4wd broken !?! - YotaTech Forums, and my 4wd is not stuck, it never engaged and don't heard any grinding.
What do you guys recommend now?

Bumping this old thread because I'm having the same problem... tried to engage 4wd, it wont engage, and the light keeps flashing?? I use the 4wd all the time so I know all the tricks to get it to engage ( neutral to reverse, drive in an 8 figure, etc) but i recently had my front end worked on some I'm wondering if something got messed with? Any ideas where to start looking disconnected parts? I dont think anything has gone bad because I use the 4wd 10-25 miles a month.
