I am trying to locate the transfer case control module on my pickup. It is not on the passenger side kick panel or on the drivers side under the dash. Any ideas?

I have replaced the actuator, the decoder motor and transfer control module. When I put the fuse in, it is making a clicking sound with the key off and engaging the 4 low, and the lights on the 4x4 switch are blinking. I have the electronic 4x4. I had to replace the transmission, before it was replaced everything worked, any ideas?

Check your connections all around and scan for codes. It may be a short in wiring, also put your old tcm back in and see if it still clicks etc. If you ever have a problem with this vehicle you should always scan for codes first.
