    No power driver door 05 lly

    The orange wire on the door side of the accordion boot. All three of my '05s in the fleet broke the, and 2 '06s. Most of them would work when the door was partially open. At least when the symptoms first started.

    Question: Computer problem?

    Maybe the odometer reset button is stuck inward (either the one in the gauge face, or the equivalent one on the steering wheel, if equipped). I know holding it in long enough does change the language.

    Inverter remote outlet install

    I've got inverter and outlet pics over at dieselplace. My inverters are shoehorned in behind the flip rear seats, and, I've installed GCFI outlets in the B-pillars, and small square outlets in the rear of the center jump seats. Over there, Diesail has some nice inverter write-ups, with...

    Drive train clunk over bumps causing ABS to engage

    I'd be looking at the RF WSS for signal fallout in the 3-10 mph hour range. With no light, there'll be no codes. If it were the VSS in the transfer case, the speedometer would be erratic at higher speeds. The WSS's will send incomplete data at lower speeds (under 10mph) if the sensor has...

    LBZ: Turn signals steady on. Why?

    To the OP, you'll need to replace the LM455 flasher module. A search of "LM455" should even get you to replacement instructions.

    Slotted Rotors

    The NUMBER ONE reason for warped rotors is that one or more corners of the truck have binding brake hardware. Regardless of what rotor you use, or pad, you HAVE to correct the underlying fault, PERIOD. A thorough inspection of the components and how they slide/ fit is in order, AT ALL FOUR...

    Bluetooth for 08 LMM nav

    I put in the 20783877 on an '07.5 that I bought from GM using a VIN from a non-nav truck and it doesn't work. The dealer isn't smart enough to flash it correctly, yet. The install was super simple. I believe the VCIM needs to be flashed to a Nav headunit setting, which, unfortunately, I...

    Question: dome light ground location?

    Obviously, I'm not helping much here, but, one more test. With the truck in gear, does cycling the dome override button 4 pushes defeat the DRLs?

    Question: dome light ground location?

    Alright then, my suggestion didn't help there, BUT grounding the gray w/bk wire did turn on the lamps, so the relays are good. The BCM is suspect, BUT the dome override can still be at fault. Unplug the dimmer switch assembly. Do the courtesy lights work (they shouldn't)? Now, with the...

    Question: dome light ground location?

    Not to pic a nit, but I asked to have the EXT ILLUM relay (for the parking lamps) swapped with the CTSY Lamp relay. The INADV Power relay feeds power to the courtesy lamps, and voltage was verified, so we don't touch that one as the OP verified power at the lamps. So, we try a...

    Question: dome light ground location?

    He already verified power, so the CTSY Lamp relay is the ground control, so it needs checked or swapped.

    Question: dome light ground location?

    The white wire to the lamps becomes grounded when the BCM commands the CTSY LAMP relay to close. The orange wire is the 12V supply from the INADV PWR relay. You know the INADV PWR relay is good and functional, as you have power to the lamps. I'd swap out the CTSY Lamp relay with the EXT...

    Check all your TBC fuses in the interior fuse panel.:thumb:

    Question: dome light ground location?

    Why don't you just change the blown fuse??? TBC 2B (15 amp/ blue) in the interior fuse panel. BTW, I'll bet your reverse lamps are out, too. If that one's good, check all the fuses that start with TBC.
