Hello everyone, my friend has a 2016 Ram 1500 with non functional windshield wipers and I am trying to help him fix it. He already changed the motor and still has the same problem. I did as much diagnostics as I could without a wiring diagram or service manual, which included visually inspecting the connector and wiring, checking the fuse, and checking for power at the fuse.

At this point it seems that the problem is either in the TIPM (underhood fusebox) or the wiring as I can hear a relay inside the box clicking when the wipers are turned on, so it would seem that the multi function switch is functional. However, I'm not able to go much further at this point because I am unable to find any wiring diagrams or information.

Does anyone have any advice on how to further troubleshoot this issue or wiring diagrams? Thank you very much in advance, any help is greatly appreciated!
