relay location for shift on fly F250

Sorry I can't offer any help, but after reading your post, I am even more glad I ordered my 2005 F-450 with Manual transfer case and manual locking hubs...

Good Luck And Merry Christmas

Well now, here's something to consider. We bought this truck a year ago. It was used and it now has 90k on the clock. Still young in the life of a truck like this I know. BUT - we do have manual hubs, 6 speed manual tranny and everything had been working fine until it went to the shop. It's the manual transfer case that we are lacking.

We suspect that something either got bumped or blown diring the R&I of the tranny. There is no telling what this truck went through during the first 78k miles while it was in Texas. It looks as if it had been maybe a ranch truck or a work truck. Not really abused, but not owned by Joe the commuter. It's a good truck, things just go wrong when they get some miles on them.

When the dealership opens up on Monday, I'll call them.

Happy Christmas CJ

I don't know the solution as I have manual everything. However, I believe that the transfer case uses a motor to change operation. A motor must have some sort of connection. Craw under and look for a loose electrical connection.

Pete & Mellowed, Will check these and post back Thanks! Kate

I'm going through something very similar right now with my 2001 Ranger. No 4WD until I blast the interior heat for a few minutes to warm up the

4X4 control module behind the passenger side kick panel, then it works fine. I suspect the relay in the box is sticky. I have a new one on order. For the heck of it, try blasting your heat if you're not in a warm climate for a few minutes and see if you get 4WD back.

I'll tell him to give it a go, and get back to you.

Hewy Mark, He was just pulling it out of the shop when I told him. He said that it had stopped working while we were running errands, and the heat had been cranked up.

Sorry...

Thanks Kate

Hope you get it fixed. Mine is definitely being caused by the "4X4CM" module. I localized it a few minutes ago by letting the cab get cold until it wouldn't go to 4WD. Then I hit the module with a heat gun, and it started working. I'm hoping the internal relay is the one Ford sent my mechanic, as it's $50, and the module assembly is $150. It looks like it's meant to be opened, so hopefully it'll be fixed tomorrow.
