no power to tranfer case motor
1997 ford f150 150,000 mi. i recently engaged 4 hi, the dash light came on, then went out and the tc motor would not disengage. i got under the truck with a hammer while my copilot flipped the dash switch. no luck. i removed the motor and manually turned the tc back to 2 wheel drive. i bought a new tc motor, installed it, and discovered i have no power to it. i have checked the fuses, all are good. i have read that there are relays, but im not sure how to check them. any thoughts and or advise would be great.

i was able to get access to a scanner. came up with a P1820. which basically means that there is a problem with GEM (generic electronic modual). mine is located inside the dash, behind the radio, or so im told. i have not tried to enter yet. i will post more info as i go. good luck

I don't have a wiring diagram handy so I'm not sure exactly which fuse provides power to the shift motor relays. It's possible that the fuse blew during the 2hi-->4hi shift or maybe the clockwise shift relay is bad. Might be just a bad wire or flaky connection to that relay too.
