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

[gooffeyguy]

wierd I thought they showed different but I think I only had the message come up twice in the last 7 years

Yeah I use the overhead switch a lot while sitting in it while running to open/close the liftgate. Like when picking up groceries or something and they bring it out to your vehicle.

 

[mikez71]

Is the ajar switch separate from the closure mechanism or is it in the mechanism and just has a separate wire connector?

Just saw this on rockauto where it looks like the liftgate ajar is a separate switch...

More Information for GM GENUINE 15299399

Looks like the liftglass ajar maybe integral to the latch mechanism..

Was out and about today in thecopcar. Opened the liftglass a few times. The last time I felt the cover on the switch disintegrate. It’s always something.

 

[mikez71]

reminds me, I need to order one!

Mine's been broken ever since I got the truck a couple years ago and rubber is all gone..
and button guts I suspect as well..

yeah, the rubber button cover on mine fell apart about a year ago and I replaced the entire button

Shouldn't be a low battery. Just replaced it less than a year ago.

My alarm (horn honking) just went off about 10 mins ago while it was just sitting in the driveway. Haven't driven it at all today. I looked at my security cameras and I saw nothing, 4 legged or 2 legged that could've set it off. But at the same time I could hear another milt-sound type of car alarm going off a few houses down across the road.

What would cause the factory alarm to sound, the door opening? Ignition starting without chipped key? Shock/glass breaking?

A low battery can set off the alarm. Check her state of charge with the Tech-2.

Ok well, I haven't done anything to it yet.... But in 4.68hrs I'm embarking on a one hour drive that will likely result in my building an OE track width Pre-Runner? Picking up a pair of Fox Factory Series 2.5 Remote Reservoir front coilovers. They are 4" longer than factory at 23.46". And I plan to upgrade the reservoirs to the new DSC high and Low speed adjustment dial system.....

They were fairly cheap on Amazon so we’ll see how long they last. Fit was fine. Seals all looked good.

Link?

Just a friendly reminder to change the plastic Ts and the hoses going to them from the water pump. I previously changed the Ts but not the hoses. One of mine cracked yesterday and left me on the side of the road while it was 95 degrees outside.

Yeah I try to remind everyone of that fitting, it often get's overlooked. Here is a Delco one that you can just clamp the hose to. Maybe throw a spare in the glove box too.

dropped it off at the dealer, there going to put a scope on it in the morning tomorrow and hopefully get to the bottom of it

@mikez71 I had to do this on theothertwin after I got it. Not hard, but finicky making sure the plug doesn't retreat while you're half done.

guy at work has a 08 truck with the 4.8 in it. tapping like crazy, heard it across the parking lot at 430am. I walked over to talk to him, he's like it's been like that forever. revs it up and it goes away, idles for a bit and starts tapping again. 200k and he says the truck 4.8 never had the afm. truck didn't even have oil pressure gauge on the dash and he's never looked. just when it gives up its going to the junk yard. not worth fixing.


kinda wild just drive it around tapping. he said it sometimes goes away for months at a time and then comes and goes.

lol, my 03 silverado that I sold to my sister does the same thing 284k+ on it, taps at idle after sitting for a minute and comes and goes usually months at a time, it's good truck, she refuses to sell it back to me.

Bizzaro sh*t, new maf installed, fuel pressure is high, misfires under a load only, even revving to 5500 in neutral no misfires at all

Rank amateur here but is it possible the ecm is misreading the MAF input?

dealer said they took a look at it has high exhaust pressure, suspect 3rd cat is clogged, so they said get that looked at and put the stock airbox back on it and bring it back and then they can get more accurate readings

Hopefully that fixes everything.

Replaced failing alternator. Overcharged my AC. Probably observed all laws regarding disposal of excess refrigerant. Avoided examining u-joints.

I'm surprised they last so long tapping like that.
