I figured I post this to help someone else out . Turns out my windshield seal has bin leak since just over a year old and I never saw it. Made lights go wacky and wipers after heavy rain about 6 trips to the dealer over 3 years they finally found leak and it was leaking on the light control module finally fixed

I thought I had fixed the code I was having by changing the light switch but it wasn't. Seems windshield was leaking and got lcm wet I want to check the plugs to it. How hard is it to get to 2019 granite

Well turned out it was the switch,figured I let you guys know incase it happens to someone else

Well I see I got views , gonna change the switch today.if the truck sits overnight the blue switch lights work , code still there if I turn switch off then back on they stop working

2019 granite ,ok here is the problem if i start the truck with headlight switch off i get this code and check is lite up on dash with lcm code. if i turn the headlight switch on and start the truck no code as soon as i turn switch off code pops up . could this be a bad switch ? or wire or lcm. i had it at mack they said everything was good when i picked it up as soon as i stated it code poped up. didnt go back in they where closing and i had to work

ok i will check it tomorrow coolant level in the plastic tank looked full though, thanks

2019 granite got a pop up message , check coolent at next service interval . what does this mean it went away. called mack no clue

About 2 months ago had a new steering box put on by the dealer. Steering would get stuck turning left, they did a pump pressure test 2555 cold 1500 turn left or right hit hard spot turning would drop to 750. Ok now my problem is can't turn the steering wheel left or right while stopped an loaded 2019 granite triaxle dump. Is this box garbage or do I need a pump ?

Yes center piece then right panel then 2 screws holding in filter

Well figured it out , it for trailer hookup plug

R3 relay lights where blinking wipers going when I turned key on, pulled this relay under hood and it stopped everything works. Is this relay for a wire to the back of the truck for a trailer hookup it's a 2019 granite triaxle dump no trailer plug in the back

Wondering if this was ever resolved

Is there a filter in the reservoir? If so how often do you change it

That seems cold my 2019 runs 225 goes 235 or so pulling

2019 granite squeak in dash I think I found it.took the top panel off and I look in the little square holes, there seems to be what looks like a computer box I can move with long screw driver moved it around and now it stopped. Does anyone know if a screw came loose or it kinda lays there ?

Take the cover off the unit an clean the coil , guaranteed to be full of dirt

Wipers seem to get stuck for a second on delay. When I asked the dealer he told me wiper motor is not in warranty. Has anyone had this problem and is it the motor ?

i have a cricket sounding rattle seems like its coming from behind this panel. does this panel just pop off ? picture off the web

Does anyone know the part number ,what it's called mack says it's back ordered. The felt is gone off the rubber..the part that's circled.

I bought a set from them had no problems
