Weird electrical issues still happening

I experienced the same wacky issues with my tractor dome light. Fortunately, it hasn't acted up in a while.

But if your cruise control quits working, it's probably the brake switch.

 

Its your PBDM I Believe is the name for it...the power disconnect switch controls this and sometimes they bother. The whole deal with the wipers going on their own is a associated indicator of the PBDM Being defective. Its on the firewall under the hood on the driverside.

 

Wrong.
Go ahead and look up some wiring diagrams and SHOW me how that is even remotely a problem. Do you even know how a wiper motor works? Do you even know if the OP's truck even has a PNDB (which you clearly don't know the correct acronym for)?

 

I could be wrong because lemon laws go state by state, but in most States lemon laws do not apply 2 commercial motor vehicles. I know here in Pennsylvania for sure that the lemon laws don't apply.

From what I understand there are legal ways to get compensated for the problems, but nothing easy and cut and dried as a lemon law.

Something to think about before you buy a new truck I guess

 

This might help with ideas Car Won’t Start But Lights Come On?
Cars, vans, buses, tractors, race cars and motorcycles all have electrical issues. Try searching using other keywords like symptoms, stuff, thing, blinky etc.

I actually had a similar problem with my windshield wipers going on. It had something to do with the security system in my car. Can't remember how it got fixed.

 

@Irishblood_83 did you have the dealer look at that service solution like I mentioned earlier? Did they inspect all other grounds? Like the one directly under the cab...those related items.

 

In a freightliner. When the high beams are on the dash board lights and gauges play up like you have just put the key on and the truck is going though its pre check. And the voltage meter keeps on dropping.
