THANKS, this saved me big time as I’ve had the flashing light problem for years but also have problems from time to time getting to/from 4WH back into 2WD. I’ve been stuck in 4WL for over a day now, read this article and took the unit out, checked the wiring and sodering ect, put it back in and everything is working fine now. I was going to have to rent a car for a 5 hour drive tomorrow so this saved me BIG time!!!!

Just wondering if anyone else encountered no change after reflowing the pin solder connections?

resoldering the pin connections fixed the problem now the lights all illuminate appropriately, and all four wheel drive functions are normal. I just soldered the pin connections with the board still connected to plastic housing no problems thanks for the tip

I’m 100%, three for three with that switch. It went bad on my ‘99 GMC Sierra, ‘99 Silverado and now my ‘00 Silverado. I paid the big bucks for the part the first two times, now I’m heading for the soldering iron. Thanks to all.

I had the same issue and replaced the transfer case switch with a new onel problem solved for $60.00 vs. $200.00 plus for a GM technician to troubleshoot and replace it.

I bought a new switch from my local dealer for $61, listed for $76. The part number has changed to 019168767. It took me almost as long to remove the dash as it did to replace the switch. Works like a dream

Hey guys… those of you that soldered the connections… did you remove the board from the plastic or just solder the exposed connections on top? Thanks

Trey… my ‘05 does sometimes shift into 4 Low at startup and is hard to get out of 4WL. I’ve had this problem since day 1. Took to dealership under warranty and they kept it for 4 days said no problem found. I finally paid $90 for a switch and replace it myself… no problems for about 6 months and then it came back. I’m at a loss. I just pulled my newest switch and am going to check for cold solder joints.

Thanks for the info. I resoldered the connections on my 2000 Z71 and it worked! The info and pix help a bunch.

I had the same problem on my 2004 Z71. I priced the part @ $83 through the dealer and $64 after shipping through GMpartsdirect. Instead, I resoldered the connectors inside the switch. 20 minutes start to finish! Works like a champ!
