    Weird codes being thrown

    I've got a 2004 Chevy Tahoe Z71. I've been getting weird OBD codes for several weeks, with the strangest one being 'P0C8B,' which reads 'Hybrid/EV Battery Temperature Sensor "I" Circuit High.' That's weird, of course, because the truck isn't a hybrid and doesn't have a hybrid battery. Any...

    2004 Tahoe Z71 Roof Rack Paint?

    Anyone have any ideas/opinions on the best way to repaint the roof rack on a 2004 Tahoe Z71? I'm talking about the metal(?) bars that run parallel to the body - not the crossbars or the plastic end pieces. The metal pieces on my rig are pretty badly faded and in need of some freshening up...

    Squeaks Over Bumps

    I've got a 2004 Tahoe Z71. Bilstein shocks in front. MOOG suspension components (heavy duty) in the front, to include sway bar bushings, upper and lower control arms, tie rods, and sway bar end links. Problem: I'm getting a squeaking sound from what sounds like the driver's side front end...

    Thoughts on these wires?

    2004 Chevy Tahoe Z71 w/ ~218,000 miles. I'm replacing my aftermarket receiver with an upgrade and spent some time today pulling out the previously installed aftermarket harnesses. It was a bit of a mess. Got everything out, leaving only the original GM radio and OnStar harnesses. But, I...

    Added dual USB port to console.

    Just spent about 30 mins installing a USB port where the aux power outlet / lighter plug receptacle was on the front console of my 2004 Tahoe. Easy install. Took the time to learn how to make a clean tap into the fuse box with add-a-circuit fuse holder. No splicing, and it’s fused so it’s a safe...

    Sunroof track arms have snapped - any experience with a fix?

    Hi. I've got a sunroof problem on my 2004 Chevy Tahoe Z71. Haven't found any threads that deal with the issue. The arms along the track that guide sunroof glass back and forth have snapped (old age I guess). I haven't gotten any quotes from a dealer or shop on how much it would cost to have...

    No oil cooler lines?

    Can anyone chime in on why some 03-06 model year Tahoes have oil cooler lines and others don't?

    New trouble codes thrown after remote start install

    Sensor on top of front shock

    Good day, all. I popped the hood today to investigate the weird rattle coming from somewhere in the engine bay. Much to my dismay, I found that the bushing and top bolt on the passenger side shock had been sheared completely off. No idea how that happened, but I'm pretty sure it's the source...

    BCM Flash Relearn...with new equipment?

    Does anyone know if performing the flash relearn after having installed switches and harnesses will allow the BCM to recognize and learn the new switches? I've got a 2004 Tahoe Z71. The 03-06 model years come with heated seats as an option, but I didnt' get them when I bought the vehicle...

    Torque Specs for Front Seat Bolts

    Good day everyone. Does anyone have info on the torque specs for the front seats of the 03-06 GM family? Haynes manual tells you how to remove the seats but doesn't give any torque specs for reinstall. I wonder if there are any, since the manual usually states them elsewhere throughout...

    Spare Tire Lock Cyclinder Housing Retainer

    Anyone found a good solution for getting a new spare tire lock cylinder housing retainer in place? I bought a new one after I pried the old one off (I don't know how you do that without ruining it and preventing its re-use) for a new rear bumper install, but having a hard time getting the new...

    Tahoe Heated Seat Control Switch (What Do THOSE Buttons Do??)

    Does anyone know what the EXIT, 1, and 2 buttons on the top picture control, as opposed to the bottom picture, which doesn't have those buttons? These switches are for Tahoes up to 2002, so it looks like the top is the driver side and the bottom is the passenger side, but wondering what the...

    Small block or big block engine?

    Been looking for some background on engine size regarding the "block" size. Most of what I've found talks a lot about Chevy's history with block size engines and deal mostly with classic muscle cars. Wondering what my 2004 Tahoe 5.3L FFV engine is? Presuming it's big block?

    04 Tahoe Alternator Ground?

    I've been watching videos on how to do the Big 3 upgrade to my ground and power wires under the hood. Noted that one of the Big 3 is a ground wire from the battery to the engine block, which many attach at the alternator. Also lots of videos recommending that the alternator be grounded from...

    When the blend door actuator recalibration makes things WORSE(!?)

    After noticing that my driver side blend door actuator (the one that controls air direction - floor, front, defrost) had stripped gears, I installed a new actuator. I plugged it into the wiring harness and performed the re-calibration procedure (pulling and replacing the fuse, turning the...

    Maddening undercarriage rattle!

    I'm being driven nuts by what sounds like a rattle (maybe even a squeak, too) that I hear only when I go over small bumps on holes in the road. It doesn't happen when I go over speedbumps or anything large like that...so it's like the "micro terrain" is the only thing that causes the noise...

    [SOLVED]Engine sputtering at idle AND speakers are popping

    Hey folks - Started the truck (2004 Tahoe Z71) a couple of days ago and found that the engine was sputtering at idle, during initial acceleration, and quite a bit more in reverse - to the point it almost feels like it's gonna stall out. Don't really feel the sputtering at speeds. Also, when...
