On more than one occasion my transfer case would stick in 4 high or 4 low before I fixed the switch. But after… that’s not a good sign.

Make sure your transfer case fuse is good. On my 2000 silverado it’s labeled ATC (Auto Transfer Case) and is located in the main fuse box under the hood.

I put a new switch in but I’m pretty sure i need a new T-Case cause, now its just stuck in 4High, witch isnt bad if you use it alot.

This has driving me nuts, service 4w drive indicator pops on after a few miles, I spend $400.00 to service the 4wheel drive; Just to go about 10 miles and have the indicator pop on again. The service people just scratch their heads and say they will have to look into it. I re-soldered the connectors and it shifts perfect. Thank YOU, Thank YOU.

I replaced the switch and that apparently isn’t the problem. The light is still on and the selector switch does not work. Now what?

Thanks, saved me a service call. Took the unit out, soldered the top connection on the connector, cleaned the contacts and reassembled. Took longer to find the soldering iron then fix the problem. Fixed the power steering pump last week now on to the power window that won’t roll down. I have to say I am dissappointed in chevy since these are known problems perpetuated for several model years. This web site is awesome…. and thanks for the tips…. Saved me at least a grand in repair bills.

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.
