Lighting problems

In the history of mankind 2 things are undefeated.....(1) time (2) water. What would possess an engineer to on purpose mount a computer module where the elements rain,snow,salt,dirt etc. can get to so easily? Just my mechanic rant for the day.

 

Well, if we are ranting....why have a electronic module for lighting to start with? Something that can suddenly leave you without headlights at 70 or 80mph out in the middle of nowhere with a load on that is tired, thirsty and needs to be off the trailer before they start losing the will to live.... and oh yeh, what about the good old days when you could watch free air tv during a storm without loss of hd signal? May not have been the perfect picture but it beat nothing. And we use to have a pretty inexpensive electromechanical gadget call a VCR that you could press a button or two and record anything you could watch on said tv- free or pay. ... Electronics own us now.... They call it progress..Sorry for the OT rant.

 

Having this issue now, what did you do to resolve it?

 

I am having the similar issue with a 2021 579 the marker lights come on will be on for an undetermined amount of time and turn off just the hood, front and side markers turn off the turn signal still flashes. Sometimes it is hours and some times seconds they stay on.

 

Hood harness is popular to rub around hood support bar where it wraps around.

Also check hood harness to chassis harness connector LH side of radiator for moisture intrusion or corrosion.

 

I did not find any chafining on any lines the only problem I found was the drivers front marker was shorted to the flasher inside the bulb. I changed the bulb and so far 3 hours lights are on.

 

I like easy fix and cheaper too. Hope it stays fixed
