    Factory Bose Entertainment System: Radio Lights Up. No Sound

    I see this has been been discussed more or less but not in the specific way I'm looking for so I'' ask another question. Factory radio lights up as it should and has full functionality other than sound. So I know the fuse is good as it has power. My question: Is there another fuse for an...

    Headlight Aiming

    I did a search and haven't found what I'm looking for and that's a DIY method for aiming the new headlight assemblies on an 03 Tahoe. Back in the day, with sealed beams, I had what I needed to get this done. Now, with these new one piece units and two adjustment screws, it's quite the same. Can...

    Headlight Adjusting Screws and Related Parts

    Hey All. I'm in need of the headlight adjusting mechanisms for my 03 Tahoe (looks to be the same as my 06 as well). The plastic inserts have split and the threads stripped. Some worse than others. Looking online at the parts I think I need and I'm informed that they are not compatible with the...

    Sunroof Stuck Open

    My 03 Tahoe has the sunroof stuck in the open position. The fuse is good. I haven't investigated the relay located in the R/S A pillar yet. If I can't operate the sunroof by jumping out the relay, the common approach is pull down the headliner to get to the sunroof mechanism. That is a major...

    E-brake cable stuck...

    Besides a host of other issues with this heap, this one popped up today. A little history. 03 Tahoe 4WD. Previous issues with the ABS motor (open circuit somewhere according to the Tech 2 DTC C0267) That's not an issue in and of itself as I don't mind not having ABS or traction control. What has...

    Spark Plugs: Nickle vs Others

    Others being Iridium or Platinum. AC Delco R44LTSM is the old school stuff. Almost exactly what I run in my hot rod small block Chevy. That said, while this plug IS available and spec'd for the 2003 Tahoe 5.3L (LM7) so too are the NGKs, ( It seems all of the relevant part numbers are now...

    Wanted: Headlight Adjusting Screws

    I've searched the Dorman catalog, checked Rock Auto (to name a couple) and have come up empty. Searching here yielded one non-result. Anyone have a PN or source for the headlight adjusting screws? (03 Tahoe). I see one of mine has had the hose clamp treatment and couple more let go the other...

    PCM and BCM removed and reinstalled

    Quick question as I work through a litany of issues with this 06 Tahoe. During the course of trouble shooting I have removed and reinstalled (without replacing) the original PCM and BCM. What are the requirements after this has been done? I understand that a key re-learn is needed if the PCM has...

    Tech 2: No communication message

    I'm looking for the short answer to the "no communication" message I get when working with the Tech 2 and my 06 Tahoe. Some research shows that several modules have to be tested (via a multi-meter). Anyone experience this and care to share a shortcut to a solution? Thanks in advance.

    Did a search but didn't find what I'm looking for specifically. Subject: 2003 Tahoe with the Z55 Autoride suspension. The Autoride function is damaged beyond any reasonable repair (to me).

    O2 Sensor Part Numbers

    A scan of the fault codes indicates an O2 sensor has failed. I've gone through the list of my on-line parts supplier however they aren't entirely clear. All part numbers are associated with upstream and downstream sensors. So far I've come up with: 15730, 15284. Does anyone have a list for the...

    Upper and Lower Ball Joints w/wo Hub Removal

    Subject: 2003 4WD Tahoe A dozen searches seem to produce a dozen different answers. Same with watching some of the (inane) YouTube how-to videos. My question: Is it entirely necessary to remove the bearing/hub assembly when replacing the ball joints? Obviously I'm looking for the simplest...

    PCM Ground Circuits and Locations Wanted

    Where is the best resource to find all of the locations for the grounding circuits for the PCM? I've checked the usual website and online sources however most seem available by subscription. Anyone have any links? Maybe there's a specific OEM manual other than buying the entire set of books? I'm...

    PCM Swap and Compatability

    What is the criteria for swapping a PCM from one vehicle to the next? Example: My 2006 Tahoe is dead in the water. I have an opportunity to purchase a running 2003 Tahoe for very few dollars. In an effort to find the solution to the 2006's no start issue, can the PCM from the 2003 be...

    Here's one for you: While driving, passing over rough roads (as in a pot hole or rutted gravel roads) will result in the truck experiencing what seems to be a complete electrical failure. It's instantaneous in that, the door locks will change position, the information centre will reset some...
