97 Expy E.B. 4wd switch is not working
Hey Everyone, got a 97 Expy that doesn't want to shift into 4wd, usually when I switch to 4wd there is a clicking sound when shifting but now, nothing. I checked all the fuses inside the cab and under the hood, all are good, does anyone know if there is a relay that runs this switch, the manual does not list it under any relays. Any help would be appreciated. Thanks.

I don't know the fix but I have the same problem. I get around it by disconnecting the neg. battery cable for 15-20 seconds. If this works for you then if you engage the 4WD about once per week it appears to continue to work.
Good Luck

Potential relay problem
I had a similar problem in my 2000 expedition. There is a relay in front of the steering wheel under the dash (remove dash...) that was the cause of my problem. The switch tested good, but there was no signal getting to the trans. I "coaxed" the relay into working w/the back of a screwdriver, and then got a new one from Ford.
Don't know if it's located in the same spot on your truck, though...
Good luck,
Rick

I had the EXACT same problem on my 98 and took it to Ford. Here's what you need to do. Disconnect your battery for a couple of minutes to reset your computer. After you reconnect it, try shifting to 4Hi and 4Lo.
If it shifts, it's not your dash switch, vaccum lines, GEM, or fuse/relays. It will be your shift motor on the transfer case which is $300-$400 from Ford(labor not included). Probably much cheaper from a third party. This is a part you can install yourself if you were inclined.
If it doesn't shift..... Hmmm. Then check vaccum lines and fuse/relays. A dash switch from Ford is $20 and takes about 5 minutes to install.
