Plow truck 4x4 not working

[walleye guy]

There is snow in the forcast and my 99's 4x4 is not working. I brought my truck in to get scanned and when it was hooked up, the scan tool showed that my switch was working.. could see when switch was turned from 2x2 to 4h and 4l. The mechanic told me that the acuator motor to the t/c was not engaging. Checked the connections and were ok. I switched out the acuator motor and still nothing. There is no light showing on the dashboard. I checked the fuse and it was ok. Any ideas would be appreciated. Thanks!

Was it one of the connectors that go to the acuator moror? So what did you do to fix the problem? Change connector or wire or ??? Is there a way to figure out if it is a connector?

When you switch to 4x4 can you turn the front drive shaft? If not the accuator on the t case is working,but maybe the lockouts arent, or just faulty dash light.

I don't know if it matters or not but when I start the truck the 4x4 light does light up, so its not burned out. I have not checked the front axel.

I have auto locking hubs that I know don't work. I did have the manual hubs engaged.

this is hard to explain. go under truck, drivers side, roughly in the middle of the tranny towards the top. towards the engine you'll see wires and a plug connection,make sure it is tight. ifs thats tight checks fuse. or your 4x4 switch
