Update fellas! Changed out the encoder and changed transfer case fluid and all is good so far. I believe the loose connector flopping around was the problem. Thanks for all the help guy's. Good to know people still driving them and sticking around on the forum to help a fellow TB owner out. Hats...

Welp. The TB went in to 4lo and got stuck with a service 4wd light. So I decided to put the '05 encoder motor in. When I got under there, i went to disconnect the plug and it just felt like it was barely connected. I also noticed the plug was not secured to the little bracket. When I pull the...

Thanks for the info. I did pull a TCCM from an '05 and installed it. I also ordered and installed an OEM selector switch & front disconnect actuator. While it was out, I checked to see if I still had a spring load on the "fork" that engages/disengages the front axle. It checked good. So, this...

On a very slight incline. Basically a normal driveway incline. But not steep or anything.

I do have another encoder motor that I got from a 2005 TB. I opened it up and checked the encoder ring on it. It looked new. So I will change it out when I do the transfer case fluid change.

So. there was no light on 2hi then she put it in neutral and then 2hi light went solid and it was ok.

2hi. and it was blinking. But when she put it in gear and drove of it went solid on 2hi.

Update. So, I received the OEM selector switch (made in Taiwan?) and the new AC delco front diconnect actuator. I also checked the spring loaded "fork" on the disconnect. It was good so I installed them and everything functioned normally. Then 2 days later the 2hi started blinking. So we...

Thanx. Didn't want to go to the dealer on that TCCM anyway. So it's staying in for now.

I wonder if that cheap-o I got from Amazon is part of the problem? When I go to put the OEM in, I'll check the position and plunger. I hope it not broke inside the TC. Thanx again!

Another question if I may. I put the '05 TCCM on the '03 TB. Do I need to get it flashed? GM Part No.: 12590220

Thanks guy's for the tips. I did do the transfer case but at ~75k i believ. Will do it asap. We traded Grandpap the TB in 2012 for his 2007 Tahoe LTZ since our family was growing. Then my oldest turned 16 and we got it back for her. I see no entries in the maintenance log since my last when it...

Oh, forgot to mention, hers is a 2003 LS. I apologize for my earlier post. Just really frustrated with it. I've been reading all your post for at least 3 days and been trying different things to chase down this issue. We don't need 4wd at all here either. One of my thoughts is how to disable it...

Hi guys, new to the forum. I too are chasing this switch light blinking , tranfer encoder motor switching by itself and from actuator noises. I'm fed up with this S%!T. I have the latest TCCM in and a new selector switch and a new front actuator. So I get in the car a the 2Hi blinking & 4Lo...
