help me troubleshoot 4wd
1994 5.0L 4R70W trans electronic shift 4wd w/ auto hubs
Lately my 4wd has not been working. Historically, it would shift into 4hi all right, but now when I press the 4lo button nothing happens at all.
this past winter I noticed the same thing happening with 4hi: press the button, nothing happens.
I have verified that the truck is not currently stuck in 4wd. I have also checked fuse 18. I suspect the problem is electrical, either a bad connection or shift motor, but I don't know how to troubleshoot those things.
any advice or suggestions appreciated!
