Hands are in the air!!

Hello everyone, first-time poster! Only cause I do my research and usually find my answers very quickly... I know some of you are going to do a search of what I'm going to post and try to fill in the gaps!
I've done that already. I can't take my truck to the local Dealership (expired, and too expensive). Also I know, already how to replace a fuse, break line, brakes, gears, you know.. all the good stuff.

I'll be honest, the experience I've had with a lot of ""Mechanics"" is that they have grown to be "Parts Replacers" rather then actually finding out what the issue is and only charging for the actual fix (like the old days, even when ECU's where introduced) . I dunno...

However, here is the issue I have at hand.

The seat belt light is flashing, the Stability Control is solid, the airbags light is solid, that is the instrument panel issues observed.

I'm gonna also add that my drivers side Headlight isn't working, passenger side is great! All DLR'S are working, my added roof light and added lights on the bumper are working and have been for a few weeks! Radio JBL system not working, interior lights aren't coming on until the truck is started. I am unable to lock or unlock doors with the physical buttons, nor the fob buttons. Also, the garage door buttons on ther rearview mirror have stopped working, again at the exact same time..

I only thing I've done, before this started was replaced the calipers, pads, and the passenger side brake z hose. These had to be replaced cause well, my eldest son was helping me and failed to reinstall the caliper retaining clips, so one pin came lose and started a series of events. First of which, the pin fell put locking up the wheel. I replaced the pin and hardware after inspection. Then I noticed that one of the caliper bolts were missing, this was replaced with an OEM bolt and lock -tight was used... this bolt fell out two days later and caused the Z tube to leak. So it was replaced. And now I have all this other stuff happening.

This all happened at exactly the same time.

Bulbs, fuses, wiring all have been thoroughly checked and not an issue (unless I'm missing something), I am currently inspecting the relays, and reading the diagram..

This is a 3rd Gen (2016) <<<not late 15>>> Limited. Dealership/Shop is going to be the absolute last resort! $$$ especially since I am 10k into the build so far, just doing myself..

Frustrated new poster

 

Rodent chewing through wires?

Edit: I clearly didn’t actually read your post. But I’ll leave the shitty comment. - err, OP fooled me! I’ll get over it.

 

I would disconnect all the aftermarket wiring as a place to start.

 

Well, I kinda added details after posting, I was a bit occupied and frustrated... but, no, no rodents garage kept and parked in a secure parking lot at work, and well its winter time. Most of them critters are hiding, LOL.. although the wiring has been checked and nothing observed l, although I still maybe missing something

 

Stopped what I was doing, and disconnecting everything.

 

Comment edited again. I knew that wiring comment wasn’t there! But no worries.

I would definitely return the truck to as stock as possible then reassess. And as stupid as it is with some lights and such (such as the dome), make sure they are set to “on.” We all make stupid mistakes when we are annoyed.

 

I’d start with the easiest to diagnose.
The driver side headlight.
You might get luck and find all the problems come from the same spot.

 

ask chat gpt

 

I set the bar low with my useless comment. You knocked that bar into negative territory. Thanks for the help.

 

This makes me think the hardware that worked it’s way loose and fell out might have shot up and around somewhere grabbing some wiring on the way.

After removing all aftermarket wiring stuff, I suggest looking around the wheel well and whatnot for potential holes.

 

Tried that one no luck unfortunately.

 

True,, that's why I'm here.... I am absolutely at my limit it's been four days (luckily she still starts and drives.... work would be a little pissed at this moment LMAO

 

Can you tell me more about how you tried to diagnose it?
Does both the Hi and Lo beams not work?

The Left and Right side lights use different grounds.
Also, the Hi and Lo fuses for both sides use a different fuse.

I’d start with power at the appropriate fuses.
Then to the connector and check power
And finally ground.

 

I'll do that!!! I'm at wits end and will take any advice at this point.. or else it's just gonna be more $$$, which isn't a problem.. I'm just ornery and like to tinker.

 

Well it did a good job of summarizing OP’s post.

The poster is seeking help with a number of issues they are experiencing with their truck, which include a flashing seat belt light, solid stability control and airbag lights on the instrument panel, a non-functioning driver's side headlight, non-working radio and interior lights, and an inability to lock or unlock the doors or use the garage door buttons on the rearview mirror. The poster has checked the bulbs, fuses, and wiring, and has inspected the relays and diagram, but has been unable to find a solution. The issues began after the poster replaced the calipers, pads, and passenger side brake z hose, which were replaced due to a pin falling out and a caliper bolt going missing. The poster is frustrated and looking for assistance, as they do not want to go to a dealership or shop due to the cost.


Solution isn’t too bad either.

Based on the information provided, it is difficult to determine the root cause of the issues the poster is experiencing with their truck. However, it is possible that the issues are related to a wiring or electrical problem that occurred during the brake repair, as the issues began after the poster replaced the calipers, pads, and brake z hose. It is also possible that the issues are unrelated and are simply coincidental, but further diagnosis and troubleshooting would be needed to determine the root cause.

 

Hi for both work, low passenger works, low driver Not working even after bulb replacement. Even switched the bulbs, and same result.

Both, Lo LH and RH, as well as Hi LH and RH all are good and even replaced with brand new (Just in case. Also used a meter at all locations with truck powered and switches on. All pass.

grounding, I did think there was two... I'll check that as I disconnect everything I added, although they were added and everything worked when it happened and even the after market lights are working at onset.

 

humour us and check your cabin air filter
then check along the path you used for your control wires in the cab that something didn't happen to the harness along that path

 

Hummmmmm,, that's funny... I'll explain later.. but has been on my mind LOL

 

Gotta go, take a few things apart.. I'll be back in awhile.. still gotta work at 3AM

 

Silly question but have you scanned it to see if there are any codes?
