Weird electrical issues

[Brian Wilson]

Hey all, first time poster, but have been on here for a little while. Have some weird stuff going on, and thought I may post up, before having to take it to a dealer.
2012 Ram 1500 crew.
First off, drivers side front turn signal went out. Replaced it, 2 days later, passenger side foglight goes out. Replaced it, 5 days later, one of the dual horns went out. Sounded like a weak Miata. Bought a new horn, replaced it, and now the passenger fog is a little dimmer than drivers side. Pulled bulbs & switched them, same. The new horn only lasted 3 days, and it went back to the weak Miata sound again. I think it’s the low horn out. Also noticed while driving tonight, when I have the fogs on, and turn the drivers side signal
on, the passenger fog blinks also. Forgot to mention, when replacing all bulbs, I went ahead and replaced both sides. Seems like something electrical, but Any help would be greatly appreciated

How old is your battery, if you are lucky it is battery.

But it sounds like garden variety TIPM issues, and it sounds bad like the soder joints in your TIPM are frying your electronics. Just a quick theory w/o putting much thought into specifics. Usually doesn't do this kind of harm, but it can create a short at the soder joints and like I said in theory can fry electronics. TIPM is a fuse or relay and when they allow more amps through bad day for your electronics.

Find out every bad items relay position in your TIPM. If they all are the same relay then your TIPM is most likely toast under that relay.

Maybe it didn't fry horn, if you fix it maybe it was letting less amps through then needed. Sometimes it will go back and forth, as in your horn can sound weak, then next day sound loud.

Dont know if that is yours says HD, they have two horns? Find this for yours or verify your TIPM looks like that, the lay out. Before going further, look up hard reset ram engine and go ahead and do that. Did weather recently get frigid there?

Without having a schematic to consult with, I think you have a grounding issue that is common to all the circuits. A little bit of corrosion can cause resistance to current flow. As the amount of current increases, so does the resistance. The circuits without any current flow will likely test OK with an ohm meter.

LOAD test the battery , remove and clean terminals, remove and clean all ground wires and mating surfaces.
12 yrs old lots of rust and corrosion over that time .
