DIY: 2004 Transfer Case Switch Control Module Installation

Well, I was unable to find an install guide for the module positioned next to the radio. Most are either for older Rangers, or for those with the module in the passenger kick panel. So, after about a week of trying to find the right part number online for this year Ranger and its location, I got it.

**This install assumes you have a NON-OEM radio. If you do, then you will need to use the Ford radio tool and pull the factory radio out prior to removing the bezel.


Discovery thread: https://www.ranger-forums.com/4-0l-o...module-140263/

Parts Needed:
-New module (TM101 = 1L5Z-7E453-AC)
-Flat screw driver
-7mm & 8mm sockets
-Small torx bit (not sure the size, but maybe a T-15 or T-20 at most)

1) Disconnect battery
2) Pull off the 3 climate control ***** and the 4x4 switch ****
3) Unscrew 2 7mm hex bolts right above the climate control *****
4) Pull the bezel away from the bottom and it'll pull off (a few push clips hold it in place)
5) Disconnect all connections to the radio, cig lighter, 4x4 switch and 12v adapter (*tip: Use a flat screw driver to assist in removing the ground on the cig lighter as well as the 4x4 connector....CAREFUL, it's just plastic)




6) Locate the little torx bit straight ahead and remove it. Then, give the black cowl a slight upwards and outwards tug to remove it.


Removed:


7) Locate the module on the left


8) Remove the 2 7mm bolts holding it on (one on top and the other on the bottom)

9) With the flat screw driver CAREFULLY remove the 2 connectors in the rear. Push the tab and use the screw driver to push them out.
(Side by side of old (L) and new (R) )


10) Plug in the connectors to the new module and reinstall with the 2 7mm bolts (just snug them up...it's plastic)

11) Reconnect all parts of the radio, cig lighter, 4x4 switch and 12v adapter

12) Put bezel back in, replace the 2 7mm bolts holding it into the dash and push all the ***** back on.

13) Reconnect battery and test the switch


.............................

Fuses to check prior to doing this:
Inside
#10 ( Custer (RUN/START), 4x4 module (RUN/START))
#27 ( Climate control blower relay/blend doors, 4x4 module)
#28 ( 4x4 module B+).....This was my actual issue as the fuse was blown......check this with a tester and it may save you some money.

Hood
#27 (4x4 module)

This was fuse #28 after I tested it, found no current and pulled it:
