Every light is on but fixed pretty easily.

 

It's so pretty. Just like a Christmas tree.

Check the front SAM, perhaps. Any chance there is water intrusion into the passenger compartment?

P.S. Good for you, doing basic electrical diagnostic work first. When electrical mayhem occurs, first check the charging voltage and battery health.

 

I wonder where the water is sloshing around

 

Fixed. Thank you.

 

Ok. I'll look more for that. Thanks.

 

Now my feelings are hurt.

The jerk is the one that designed that purty display, including neither an oil pressure nor over temperature indicator light.

 

And put SAM in well/pit at the bottom of SUV, prone to drowning in water.

 

Along with sunroof seals that fail, and a "panoramic" lexan skylight, also with seals that fail, each conveniently located over one of the two SAMs.

It is truly a robust design. It needs a sump pump.

The "L" stands for Luxury; it was meant to siphon off all the posers who bought the G, driving it to Rodeo Drive and back. As it happened, this worked, except the unwashed masses also stormed in to buy the GL, attracting a whole new class of poser to continue buying the G.

It's funny because the owner's manual actually suggests crossing bodies of water.

I need to explore the well under the driver's seat. It is one area I have yet to explore. I am actually only half joking about installing a sump pump; a water intrusion alarm, like I ought to get for my cellar, which houses all the house plumbing, is cheap insurance.

OP, if your problem is intermittent, the prognosis is not terrible. You can recover a lot of electronics by rinsing with DI water and placing in the refrigerator, which is a very dry environment.

 

The skylight (aka pano roof) would be a dandy location for a pop-up gunner, like the one manning a 50 cal on a humvee.

If the pano roof were hinged and thick high tensile strength steel, or Kevlar, it could serve as a shield for a rear facing gunner. This is how you get feral leftists off your tail.

Anything would be more useful than that stupid slab of lexan.

 

Hello sr, i have the same issue as you. did you ever figure out what it was?

 

Yes!

 

Dude. Who are you?? This isn't the first time you answered a question and -while I may have been gracious in my reply- I thought "get lost jack hole".

Yet both times you were right. I stand corrected. You are the man.

 

lol. Indeed. Those would be nice.

My apologies.

 

Fixed. Thank you for your help.

 

FYI dielectric grease = (mostly if not all) plain ol' silicone grease

Congrats. Count yourself deeply fortunate it was just wiring and not modules.

 

Wow all the GLs are experiencing very similar symptoms around the 10ish year mark. Lot of time for things to get plugged up i guess.
Also 2000 to diagnose is insane. Are they insinuating it will take them 13+ hours at 150/hr?
Diagnostic time goes by hourly rate. Scum.

 

Hahaha I have the same deal going on. Happened to me driving through the mountains.
Found my roof rack bolt at the rear leaking. I will cap off the rear squirter as well.
thanks for the tips.

 

Mind sending me pics of what you do? I could be wrong about the washer fluid.

 

The previous owner I assume it was the dealership. They never put the nut back on to tighten the od to the body.

 

Am I looking at the roof under the headliner? And it was a mistake by someone?

 

well idk for sure all I know is the nut was not there and the rear roof rail was not clamping down on the pad seal and roof.
tightened it up rained all night and it’s dry now.
before with a light rain it would leak about a pint in 6 hrs.
