    Does anyone know what this plug is for?

    Ah. Good advice. I think I will go that route. It’s definitely a Bose system but I think the amp may not be hooked up. The door panel I’ve taken off so far had an original speaker in it in good condition. So far, the messes the po made are mostly a bunch of pretty well run relay wires for lights...

    Does anyone know what this plug is for?

    I bought this truck with lots of problems that I'm working through one at a time. The deck was in it but I never heard it make sound. The PO made a mess of some things. There are wires for an aftermarket sub amp, but I still suspect you might be right. I thought about ordering a new interface...

    Does anyone know what this plug is for?

    My deck seems to be working but it’s not getting sound to the speakers so I removed it to see if I could find the problem. I didn’t really see anything wrong but there was this plug behind it that wasn’t connected to anything. Any idea what it’s for?

    Longer Front Shocks

    I did try to put the lift shocks on without the extenders. They’re just too long. I’ll just get the regular ones.

    Intermittent Serial Data Problem

    The electrical problems seem to be fixed! Now I just need to address the noisy lifter with a new cam and lifters! Thanks everyone for all the help.

    Longer Front Shocks

    I noticed the previous owner of my 2005 Suburban had the torsion keys cranked all the way. Also, they put shock extenders on it. I thought that meant I could get the KYB shocks that say they're for 3-5" of lift. PN 565076. But they seem too long and I'm sure I'll smash them going over a dip in...

    Intermittent Serial Data Problem

    I pulled the trim out of the drivers side rear and found the harness back there. I didn't see any broken or exposed wire, but I didn't remove all the tape. It has been accessed before. I can tell because the harness wasn't taped to the plastic clips in most places. I moved it around and attached...

    Intermittent Serial Data Problem

    I got my knock sensors and oil pressure sensor in. I cleaned up the two grounds on the back of the block, cleaned my valley cover and valve covers real good and got it all back together. The rear knock sensor was full of water. It looked like it had been full of water for 10 years. I had to...

    How to fix Hot Air when A/C is on. Install new air mix/blend door actuator

    Here's a great video on how to pull the dash. I plan to do this to replace all my actuators.

    Did you ever find the solution?

    Intermittent Serial Data Problem

    Thank you BigDogYJ. That's very helpful. fixing that up is next on my list. As far as the knock sensors, I did go ahead and spend the extra on the ACDelco sensors. I'm not too worried about that job, though. I can get the intake off in 10 minutes. I've learned that just moving stuff out of the...

    Intermittent Serial Data Problem

    I finally fished the two splice packs out under the dash to try to isolate the problem while there was a loss of communication. However, removing the comb from either one of them had no affect. I expected data to return to the cluster as soon as I unplugged it. I suspect a bad ground. Hard...

    Intermittent Serial Data Problem

    Can you tell me how to access the ground in the dash you're talking about? Remove the top dash cover?

    Intermittent Serial Data Problem

    I still have some digging to do. The serial data still gets lost and comes back sometimes when I go over a small bump or accelerate. Speaking of accelerating, I swapped the bad coils with some extras I had. Then I kept having a misfire. So I popped the hood and one plug wire was off. I couldn't...

    Intermittent Serial Data Problem

    Another update, the new cluster seems to work perfectly! I think now if I can get all the check engine codes figured out I'll be able to get it inspected and registered. As for that, I knew I had a weak cylinder. When disabling one injector at a time, the one that barely made a difference was...

    Intermittent Serial Data Problem

    I have some updates as I get this thing working. Another problem I was having was not being able to put fuel in the tank. It would just click. It would take half an hour to fill it up. I went ahead and dropped the tank, took the whole cluster of evap lines off and just shook out all the carbon...

    Intermittent Serial Data Problem

    I was out of town over the weekend and got the flu so I've been man down all week, but you guys have given me so much to start with. Hopefully I can find some time to dig into this. The ECM is working fine. I have diagrams with all of the grounds and module locations. I'll start with the voltage...

    Intermittent Serial Data Problem

    No, but I just borrowed a scanner that might be able to help. It's not bidirectional and I can't start working on the truck until next week, but from all the different ideas I've seen I'm feeling confident that I'll be able to track it down. The fact that there is a power draw might actually help.

    Intermittent Serial Data Problem

    I absolutely will. I’ll be active here again now that I got this old truck. This forum seems to have held up well over the years. I got a lot of help here.

    Intermittent Serial Data Problem

    I appreciate that. It's helpful. I've actually learned a lot about the whole Class 2 Serial system from searching youtube. I have been tuning these trucks since 2009 or 2010 but I never had to learn about this system. Everything just always worked. These trucks are getting old now, though.

    Intermittent Serial Data Problem

    When I bought the truck it wouldn't start and I couldn't connect with my HPTuners. I pulled the PCM and flashed it with VATS deleted. I didn't notice anything weird there, but I bet that is the kind of problem I'm having. There is also a parasitic power draw that will kill the battery if it sits...

    Intermittent Serial Data Problem

    I'm back from a long time ago! I bought an 05 Suburban to fix up but I may be in over my head. I've learned a bit about this system since I got the truck home but apparently some module is interrupting communication through the class B serial data system. Most of the time, the gauges are all...

    :) it’s pending already. It turns out a lot of people want a manual Tahoe. Maybe Chevy should have just made one of these.

    04 Tahoe 6.0 NV4500 2wd

    It’s time for me to sell my Tahoe to pay for other projects. It has a good strong 6.0 with some lightly worked 5.3 heads with ls6 valves and a small tsp 212/218 high lift cam. The transmission (manual 5 speed) is freshly rebuilt and the engine has maybe 10 or 15k miles on it since being...
