Electrical problem

I'm working on a 93 Suburban with the 454 for someone, and I am trying to figure out why I am not getting 12V to the front axle 4X4 actuator. The fuse in the dash is good. The actuator functions when 12V is applied. I looked for any shorted wires, but could not find any as of right now.

I was wondering if there is another fuse I need to check or a switch on the 4X4 shifter? Its not the push button setup. Thanks

Typically the signal to the front comes from a switch on the tx case. Not sure where it's located though.

I'm going to check the transfer case area for a switch or bad circuit.

Old style 2 wire or the new plastic one?
Old style 2 wire actuator gets 12 volts from transfer case switch when key is on and in 4W.
Make sure transfer case switch has 12 volts to it with key on to.
Check all fuses.
