Well, the work I did didn’t work. My son in law said it started doing it again. Ugh. Sounds like another trip to the dealership with the TSB’s in hand.
So I my daughter lives in a different state. I did the work while we were out visiting. Initially I thought removing the dash panel would have been a lot more extensive but this video proves otherwise.
Just got home so I didn’t have a chance to go after this particular ground point. I...
On both sides, there was a small nut welded on; the bolts were not self tapping. This is on a 2015 Tahoe so maybe that’s why it’s different from a Silverado or a Sierra. Similar but different.
Well…I put a new battery in, cleaned the two frame grounds by the front wheels, and the one for the ground strap on the firewall. The one on the frame on the passenger side was covered with grease and gunk. The one on the pillar was beyond my pay grade with trying to take that whole dash trim...
Thanks.
Working on access to the ground on the A pillar. I have the pillar cover off but it’s not obvious how the trim piece or the speaker cover comes off. Any ideas?
Here’s a thought - what if we took it back to the dealer and asked them to inspect/clean/tighten all the ground points?
I’ve just got a bad feeling that if it’s not that - in combination with a new battery - that it’s gonna get expensive.
Agree on not throwing money at it by changing the battery, but at least it’s something to try. Two different dealers in two different states (Michigan and Colorado) have looked at it and have not solved the problem. It might be worth a shot at this point.
I’ve searched this forum and also the wider internet but I haven’t found anything that just explicitly says it: where are the ground points on vehicles of this generation?
I’m working on a 2015 Tahoe LTZ with strange electrical problems. Taking advice from @Tahoe14 I’m replacing the battery...
Worth a shot. But wouldn’t a dealer have the insight to check that out?
But to your point, if it’s possible that a battery can check OK but still really be bad, then I guess swapping it out is worth a try. I tried to see how old it was but with that weird assembly that’s on top of it I couldn’t...
