Icon7 4x4 wont engage

Hey guys i have a 2002 ford ranger edge 4.0 and the 4x4 is not working. When i turn the switch to 4hi or 4low nothing happens, the lights do not turn on and there is no clicking sound. I checked my fuses and they all seem good and i checked to see if maybe the switch came loose but nope.
About a year ago my transfer case motor went bad and when it did the light still came on and there was a click so i doubt its my T-case motor.
Thanks for the help.

Welcome to the forum

Yes no 4WD lights would almost always be a blown fuse.
Flashing 4WD lights a bad shift motor or 4X4 module

Good read here on where your 4WD control module is: https://www.ranger-forums.com/genera...-module-37720/

Now the 4X4 control module did fail in these but you do need to BE SURE that the fuses are good, not just "look OK" or you will be wasting your money on a module.

You pull out and TEST a fuse with an OHM meter, 0 ohms means good fuse, N/C or high ohms is bad fuse

2002 Ranger owners manual should have fuse labels
Look here if you don't have yours: https://www.ranger-forums.com/genera...1-models-3747/

Outside of the wiring all that is left is transfer case motor/connector
