What did you do to your NBS GMT800 Tahoe/Yukon Today?

[S33k3r]

Took my 2005 2500 Suburban to a mechanic on Monday. Trying to figure out why half my cluster has no power, the power mirrors/windows/door locks do not work, the lights on the dash don't work, and Quadrasteer doesn't work. Also, when plugging into the OBDII port, they get no signal. My regular mechanic started at the door switches which tested out good, but just couldn't figure it out (he is normally very good; he also didn't charge me for failure!). The new mechanic was recommended by a friend, and he only had a 10 day wait to get in; my mechanic's normal electrical guy had an 8 week wait. This is my wife's car and she is getting aggravated...

Anyway, if any of you have ever had an issue where the OBDII port wasn't working, feel free to share.

OBD port is fused on cigarette lighter fuse.

Original or aftermarket stereo?

Original or aftermarket stereo?

Aftermarket. It's the same stereo it has had since I bought it in 2017. I haven't checked to see if it works or not, but it does display the time; the wrong time, due to all the dead battery situations...

Done and Done. Both the fuel compensator and evap cannister have been R&R. Wow that cannister was a major PITA. Sorry no pictures because my phone died. Glad to have both jobs completed.

I was cleaning out the garage this morning, getting ready to head to the dump. I had some old car parts in a pile off to the side. One of them was the evap canister. Picked it up and it reminded me how heavy it was compared to the new one I installed. Fuel contaminated? Glad I got it changed before it failed.

I'd pull the radio and CHMS fuses. I've found the CHMS can interfere with the ODBII port. Prolly not it since yours doesn't work at all but easy to try.

First of all Merry and peaceful Christmas for everyone here.


I am a little confused, why Chevrolet did not sell Tahoes in Dubai with tinted(privacy) glass.
But, I am happy to have an new rear window, and also with "somehow updated" design from 2005 model year

Also I bought from him facelift tail lights(with black trim), but turn signal socket does not fit, but according to rockauto catalogue, the socket is the same for all model years ("00-"06).

LOL
Probably wouldn't need rear defrost in Dubai much either...

 

[diLucca]

It is with rear defroster, and maybe they used it, I found some shorcuts/burn marks in lines.

But still it is not broken like former glass

Two new front Denso Oxygen sensors
ACD 41-110 plugs with new Wires
I'm also trying to mount the Amazon oil catch can I bought over a year ago but looks like a trip to hardware store will be needed. Last week my CEL came in for the front O2s so I did both of them for good measure. I had the plugs sitting in tool box over 9 months also so I figure it was time. Boy that passenger rear plug is a jerk!! I removed the oil dip stick for more clearance and she came out easy.
