The reason I ask is because the design of the cab may be contributing to all the water leaks we are seeing. I just can't see under the spoiler on my truck to tell.

Not sure what GM engineering was thinking on this design. Build a dam and theoretically it should not leak, but even the HOOVER DAM leaks. The engineer that designed this should be stripped of his degree and made to wash windows at GM CORPORATE offices. As for GM they are sitting there with potential for a lot of expensive repair cost, as these vehicle get older.

I replaced my brake light with camera brake light,  here’s a few pics...

David, did you need to drop the whole headliner or just the rear area?

Just the rear area, I took off plastic rear panels (that house seat belt), hanger hooks above rear windows and side panels that house front belts. You can then gentle and carefully pull far rear End of headliner away from rear window trim.

 

oh and also pull rear overhead light, pulls straight down with 2 clips.

Great info, Thank you! Getting ready to start my emergency vehicle up-fit.

Thanks for the reply. Not exactly how I pictured it under there but, it does look like the water goes right down on top of the seam sealer. No lip above the window to keep the rain from directly running to that arealike the older gen had.

Davidj98, how did you get the yellow clips that hold the spoiler on to release? I can’t seem to figure out how to get something on them to squeeze them enough to release the spoiler.

Just helped a friend pull his today, I ended up shaking and pulling, if feels like you going to break them but they will release. There are only two yellow plastic clips.  Metal is also thin where they connect, the hole was a bit deformed, so we used a smaller hammer to make metal flat again around the hole were clip connects. I don’t think there is access to those clips from cab. 
 

Also make sure small black washer is is still around clip before reinstall, they fall off easily.

Thanks! I was so worried about breaking those clips that I was afraid to pull on the spoiler too much. After reading your response, I went out this morning and was able to remove the spoiler and install my new 3rd brake light. I appreciate the info!

      Gas fill door

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.

      Active Grille Delete

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
