hey guys, i have an 07 dodge ram 2500 - 5.9. previous owner was a mechanic and does have all kinds of after market work so i cant go to much into detail as my weakness is being new to the diesel world. the problem started a few weeks ago, i took my smarty jr program off the ecm *set to stock for that model*. so to update it, didnt get to update it due to compatibility issues with the computer i tried with. so i left and placed the program back after driving a few miles to a parking lot. it was then i noticed my wiper fluid sprays when i try to hit the high beams, and turning the knob for wipers also turns fluid sprayer on. ive tried to replace the multi function switch, it did not change the issue, have tried to reset the ecm by disconnecting batteries, no change, not sure if the smarty is messed up or damaged the ecm when i took it off, i currently dont have the program installed so im running stock, any knowledge or theories are welcome!

I did contact smarty, they were unfamiliar with any issues pertaining to the one im having and the smarty, since it really only communicates with certain aspects of the truck. they said to check the steering column or the tipm. thanks for your quick reply.

as for cummins nut, I got the part from oreilly's, and already returned it, I did look at the wiring and saw nothing that immediately jumped out at me, though I did not looks all that well and will do it again. the issue has been constant with no change, turn signals work fine though, no other issues with the truck that I can think of currently. few leaks here and there haha
