IG1 NO. 2 blows instantly

I'm betting it's a stuck servo motor.
Well, I hope it is, and it isn't.

 

What all have you unplugged now?

There are 2 BSM on the rear bumper. (if you didn't notice)

 

@TnShooter I've unplugged both heated seats, rear monitor system, front radar, and I think thats it. Also how would the servo get stuck? I heard it could in cold conditions but where i live is hot?

 

It does feed the Blind Spot Monitor units in the rear though.

 

Stuff falling into the dash.
But the actual gears can just get stuck too.
Dm93 is in here now. You got the good help in here now.

He does this stuff for a living. I only do it when my stuff breaks or I'm ""helping" someone esle.

 

Well yeah. That is true.
Someone said the trailer harness. And I was rthinking that.

I posted the Blind Spot monitors earlier.
Even posted the locations.

 

See post 13, 17, and 21

 

@TnShooter definitely a possibility, your help was very good and I appreciate your time brother.

 

A stuck servo won't blow a fuse (or at least I've never seen it happen).
I need to go to bed though, I'll have to continue this tomorrow night.

 

No problem.
I'd want someone to help me too if I were in your situation.

 

@TnShooter heard that loud and clear!

 

I hear you.

I'd still unplug them.
I never seen it blow one either.
But anytime I get involved, it is like the stuff that never happens, happened....

 

I'd be looking at exterior wiring alot harder than anything on the interior.

@EvaporatedMilk I always have to ask has anything been done to the truck recently (wiring, repairs, modifications, hit something, etc...)?

 

@Dm93 recently no the only modification is a light bar and ditch lights both with there own relays and wired straight to the battery, the only thing that happened that night was I was wheeling with some buddies and hit a smaller sized pothole and it started acting up immediately after that hit. Also i checked the battery and its 12volts strong. Ive been told that the BSM can cause this issue, I am thinking its a short to ground? What are your thoughts? Also thank your for your time and patience.

 

Sounds like a wiring issue.
Even more so now that we know you were wheeling, and it happened just after a pot hole.
Crawl under and start looking at wiring.

 

@TnShooter any spots in particular that people look at? Further more the pot holes hit both passenger side wheels.

 

Now that's a good clue, I'd be looking at everything under the truck and around the suspension very closely for any damaged wiring.

 

@Dm93 roger that, will do some extensive undercarriage inspection first thing in the morning. Ill take a bunch of pictures off wires that may seem sus and report back to here. @TnShooter

 

Jut a heads up on everything I went through to find a damaged wire. Test light is your best friend. I threw every kind of diagnostic tool at my issue, the test light was the only thing that helped.

My short issue here -- 10:25 on the vid jumps you right to the test light.

Troubleshooting electrical issues can be a most daunting thing, but I think that the advice you have been given is leading you to the problem.
If you look at the clues it is more than likely a short in the wiring. Hit a pothole, instant fuse blown = dead short. I’m betting that it’s the wiring to the rear end, most likely right near the bumper. You should start a pool to see who gets it right. Good luck and keep us posted.
