This expedition has a4wd mode with the light flashing. $Hi and low work fine. Where is the torque on demand and 4x4 relays located. Aldata says behind centre of dash. I removed the dash centre cover and all thats there are 3 doorlock relays and the airide module. Any body ever find them?

Before throwing parts at it, why dont you find the failure, then replace the bad part.

Have the code pulled for the light and get back to us with the code.

Not unterested in throwing parts on it. I'mlooking for the tod relay to do a pin test. There's no power on the transfercase plug, term. 16, but there is output from the jem module. A more exact location would be much appreciated. Thanks in advance.

Found the tod relay behind the dash. I tested the pin circuits and had a broken wire from the Gem Module to the Tod relay./ Thanks for Your Help Guys.
