Just wanted to share a tip about the troubleshooting the shift module/motor/switch: I followed the module troubleshooting guide to the end and everything tested fine...

Until I got to the part where you test for 12v at the t-case. I had 4.7 volts and no motor movement. I figured that the module was junk... Swapped it out with a known good one... Same result. The troubleshooting guide does not mention what to do here.

Out of utter frustration I just replaced the motor itself, thinking that maybe it was locked up and had shorted internally thus causing the voltage reading. Problem solved.

Hope this helps someone. I didn't find any mention of this issue specifically on here or Explorer Forum and have run into it twice in the past two weeks.

My credo
In theory, theory and practice are the same. In practice, they are different.
