I appreciate any help

[Fu11F1av0rTAH03]

Hello everyone, I'm mainly here on a good friend of mines behalf. She bought a 2007 Tahoe off a local guy. She got it looked at before buying but tbh her brother's an idiot. I was unavailable or I would've checked it out thoroughly. Anyway, once ol boy got her money he disappeared. Her Tahoe is having all kinds of issues. From a misfire (working on that as we speak) to the cargo hatch not working at all....plus other issues. So when the need rises I appreciate any input or insight you folks can share with me. I'm just trying to help fix it for her bc she's a single mom. Anyway, Thanks for accepting me to the Forum. Have a good night everyone. PS. I'll try my damnedest to not ask questions already asked.

Welcome from the island of O’ahu. There are a lot of knowledgeable persons on this sight. The first thing people want to know is year, model, body style, engine size, SLE SLT?, any mods done, lifted, accident damage and you can usually wipe out most of the questions with several multi angle pictures of the Hoe. And a sense of humor or extremely thick skin helps. Good luck and enjoy your time here. Aloha!

Welcome to the forum and use the Signature to post all the vehicle info so that every post contains what we need to know.

For the first thing to address: The misfire. What CEL code is there? Cargo hatch not working, meaning.......it will not unlock with the fob? Unlock with key? Latch will not release when is unlocked?

Try to get the list set up and go to the correct section for the vehicle. You already started in the 2007 to 2014 section, so stay there and use the interior, exterior , engine and drivetrain......you get the idea.

Also, if you call some of us "DUDE", we will not speak to you again, ever. If you use the word , "LIKE" multiple times in one sentence, you get the same treatment.

Welcome from Florida! I know this isn't your car but the Tech-2 and a subscription to AllDataDIY are going to be your best friends in getting this Tahoe to be trustworthy.

Welcome from Western MA (a/k/a "NOT Boston...")! --- Let's GO BRUINS!!!!!

Times 2 on the Tech 2...

And if not AllDataDIY subscription, then get a PDF or hard copy of the GM Field Service Manual (FSM) for that model year. Really helpful to have all the wiring diagrams available and all the instructions on how things come apart (or go back together).

There are tons of great YouTube how-to's, but the FSM is great to have in front of you.

Also, the FSM has diagnostic tables with step-by-step instructions to walk you through what to do and look for. The tables also have specific instructions that pertain to menu navigation and running the diagnostic and programming functions of the Tech 2.

Not any of the Tech 2-specific references in this one, but here is an example of the diagnostic tables in the FSM and shows how it walks you through one step at a time, skipping steps based on what is found...

Welcome! Yes, you will at least need something that will allow you to scan all of the modules - not just the OBD2 module. I have a tech 2 but I also have this little Innova dongle that can read all of them that I take with me on road trips. It’s designed for use with the Repair Solution 2 app on your phone, and it ships with one free platform diagnostic module (e.g. GM) included. It works really well.

A/S/L?

Oops. I mean- trim level, 2- or 4WD, code(s) scanned, any noises, and location?

Dude, that's heavy. Like, I didn't know that was, like, offensive to anyone here.


Seriously. I never knew that was a thing. I should be more careful. It's annoying, for sure.

Again, that is why I said "some of us". IMO, speaking like that on a regular basis shows lack of awareness of your surroundings and laziness. I will be in the ground at just the right time. This world is in the wrong hands.

+1 on @donjetman I bought an 07 suburban from a buddy for $1500 just to turn around three weeks later and put a junkyard motor in it.

Granted I knew it was shot when I bought it, but still. I thought I'd get more time out of it

Do what I did and buy a vxdiag nano off amazon for 140 bucks and an older Windows 7 32 bit laptop for another 100 (or less depending on what's in your closet or local deals). It'll do 90% of what the tech2/mdi/mdi2 tools will do, and you won't have to wait two months for it to arrive on the boat. It works great. You WILL need this, or a tech2, to diag this truck properly, otherwise you're gonna end up firing the parts cannon a whole lot. Get a good multimeter too. With those two tools and a good socket set you're ready to tame this beast.

On the misfire. Bought my truck last year and had a misfire. I ended up changing plugs and wires. I was shocked that 1 plug was broken and 1 other was missing the electrode. New plugs and wires, less than $120 and runs like a champ. would be good to do anyway if you don't know anything about the truck.

I have always been curious about these small vxdiag type tools that connect to a laptop versus an xtool, autel, launch ~$500 tool. Have you compared it to any of those?
