What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[89Suburban]

Check to make sure your door drains aren’t plugged up. The wiring in your doors shouldn’t be rusting imo.

Thanks they are fine. I had that problem with one of the rear doors when I got it and learned about the drain holes. There is always dampness in the doors in heavy rains or car wash. There was just enough of that white surface corrosion on the contacts to make it start to loose contact, but if you wiggled it it would work. The pin holes on the plug are so damn small there was no way to clean them. And when I tried to pop them out from the connector I damaged them. There is no vapor protection on the back of the speaker housings on these. And I have over 300K on the window seals so I am sure that is not helping.

Yup, crazy. I was looking on eBay for used ones until I figured out it was the plug.

I just realized the base model speakers are much cheaper. $30 for the rear, $35 for the front.

Reset it an rolled out of the driveway.
Set cruise to 55, was reading 15 and climbing when I exited the highway.
She plows some air, corns not helping that number either.
Normally with my driving, it stays around 8-8.5.

Stumbled across this FWTW. Don't know whether it's BS or not. Thought I would share.


transmissions "failure mode" gear selections
So for example, a 4l80e and a 4t80e default to 2nd gear regardless of selection (past PRN) in failure mode

Caption to the chart was
Use the charts to see if the unit you have with wrong gear starts is in "Fail" or "No Power" mode. If so, you are probably looking for an electrical problem. If you have gears other than what is shown on this chart, you probably have a valve body or solenoid problem.

Yesterday, took it to bring my daughter to New Orleans for her first concert. All seemed normal so I'm more confident in her roadworthiness for the upcoming trip.

Washed the 2007 yesterday after checking the forecast for today and seeing only a 10% chance of rain. By late last night the probability had gone up to 100%, and indeed we saw heavy rain for several hours today here on the Cape. Right back where I started, so will wash it again tomorrow. At least the temps have been warm and perfect for running.

Same here. I washed mine anyway leaves and road grime are making a mess. And nobody at the car wash so it's a win in my eyes.

I know the 4l60 default when it’s in limp mode as I call it is 2nd no matter what you do with the shifter. My 02 was throwing a code (which didn’t show in the DIC) due to an electrical issue with the 2-3 shift solenoid. This put it in limp mode and drove me crazy. It’s a bear to take off in 2nd and have it not shift, keeps you driving pretty damn slow. I replaced that solenoid and that didn’t fix it, so I figured it was a wiring issue. Performabuilt told me their build doesn’t even use that solenoid so I should set that DTC to not report in the tune so I bought HPT and did that. No more problem.

Well I screwed up yesterday morning.

I usually back into the driveway but when coming back from taking my daughter to school I pulled in due to it being trash day and I had my cans at the end of the driveway on the left and my neighbor had his on the right between our driveways and it was just easier (I had 3 containers and neighbor had 3, trash, recycles, yard waste).

A bit later when I went to leave for work the trash truck was there emptying the cans so I sat there for a minute or two waiting while watching in the rear view mirror. The wife's Acadia was parked behind me to my left and I actually forgot that she was off work (she's usually already at work) so when backing up I started to move to the middle of the driveway to avoid the trash cans and hit the Acadia.

The Yukon's driver rear panel just behind wheel well.....



Acadia passenger rear at same area....



It's mostly just paint damage, but there is a small golf ball sized dent on both vehicles. Right behind the wheel well on the Yukon and right on the wheel well lip on the Acadia.

Don’t feel bad I backed into the same passenger side rear and busted out two sets of lights within a month or so of one another first was a tree second I forgot I had my little trailer behind me at a angle to back into the front yard and leave and jack knived it as soon as I moved

Call one of those paintless dent repair guys and have them come out and give you an estimate. If they're really good, they will show you photos on their website or google page of their work. Good ones around where I live can fix that. Then you might need a little paint correction, might not.

My daughter backed into a tree the other night, a $4K bill!

I feel your pain. I did almost the same thing with thecopcar and my exs white fjord a while back. Rear edge of the wheel well And near the tail light.
