Soooooo I’ve done a ton of wiring work on the Ranger recently. The truck came with 0 power options. I have installed power: locks, mirrors, windows, footwell lights, keyless entry/security, backup camera, dash camera, and a new stereo (head unit, speakers, mic). I tested everything and was getting ready to put dash etc back together. Just for kicks I turned the windshield wiper switch “just in case” annnnnnnd they don’t work (same with the washer). I checked the fuse(s), relays, and motor itself all good. I bought a new switch (stalk that controls wipers, washer, turn signals, high beams, and 4 ways. No dice.
I found

where the a person has the same issue and went as far as testing and replacing the GEM module
, but had the same issues with the new GEM and did not come to a resolution.
I grounded the same wire on my GEM and the wipers work...However I’m reluctant to replace the GEM as it will be the most expensive part I have purchased for the ranger at $100+ and it didn’t solve the problem for this other person of the internet.
One caveat, I had to diode isolate the factory door trigger wires (also located in the GEM) in order to properly install my keyless entry/alarm. I was sure to do this with the plug disconnected and I didn’t touch the wiper wires , but now it’s in my head that I might have fucked something up in doing that.
Finally I’ve paid a $5 deposit and am on the hook for $23 more when a Ford tech responds on justanswer.com. Have any oppos used a service like that?
Finally any advice from the 12 volt savy Oppos? Something I might have overlooked?

Man, I hate it when they run a bunch of stuff through “modules”. Just give me some simple fuses, switches, and relays!
Do you have a wiring diagram? A good one, with wire colors and component locations ?

I went through so many diagrams... I even paid to talk to a tech at just answer.com that was not really helpful but did provide official ford diagrams.
It turns out that it was a simple wiring mistake that I made during the installation of my keyless entry system. That issue was compounded by a new wiper switch that was bad out of the box.
The first thing that I did was install the switch (mistake) then I started troubleshooting the wiring. I had to diode isolate the factory door triggers for the keyless entry system. I mistook the low speed wiper/washer wire for the passenger door trigger. So I cut out that diode and re connected. Then my wipers would go on and not shut off! I was getting ready to order a new GEM module and have it programmed by a dealer. Then I realized my mistake. I reinstalled the factory wiper switch and everything worked perfectly.
