Would somebody be willing to take a before and after shot prior to going in for replacements, then after they get the new ones? I do not think my lights are terrible but more light can never hurt.

There is another thread with comparison shots from a member before and after the new bulbs and BCM flash. Its pretty significant a difference. Sorry I am on mobile, or otherwise I would link the thread.

Wonder if the before pictures were 9012's(stock) or replacement 9011's which are 10 watts more?

A GM dealer wouldn't put in 9011 which was designed to NOT fit into 9012 housing.

Right, but when I had the 9012's in I could not see rural areas.9011's made a big difference,

Took truck in this AM for the headlight tsb. They checked it out and said my vehicle was definatly one of the ones affected DUH.... I knew that...why do they thing I brougt it in there for?

Anyway, they said they would re-program the BCM and install the new bulbs, when they come it. Hopefully they will call me in a few days. We'll see. I'm optomistic I'll see an improvement, just as others have said after they had the mod done on their trucks.

Called dealer today to check on status of bulbs. Could not find record of bulbs ordered? Once they got your money I guess they are done with you! Won't say what I thinking.

Had this improvement done today at the dealer. Ordered bulbs a couple weeks ago and they flashed the BCM and replaced bulbs, as well as 4 recalls that were outstanding. Half way home as it became dark, the passenger side shown left across the drivers side into oncoming lane. The "veteran" mechanic (so I was told that did the work) must not have seated the passenger side build properly, if that's possible. They are obviously considerably brighter than stock but with what appeared to be such poor alignment it was hard to see much in the way of improvement. I'll have to pull that side apart and check the bulb.........never ends.

      2019+ Brake failure, it's complicated

      By needafix · Posted

      I'm not sure if this should be a new topic, let me know if it's out of place. This my first post. Thanks 85077522 - AC Delco GM Genuine Parts Brake Master Cylinders. Anyone else had to replace this brake master cylinder yet. I didn't do any brake work, it looks like new parts and I've had the truck for about 4k miles, 119k total miles.  When it started to throw codes I did the calibrations with a bidirectional scanner and got the codes to clear but they came back so I did the routine; base bleed, automated bleed and final base bleed. All that with Bosch ES16-32N fluid (please look it up). That seemed to fix it but 100ish miles later it failed again so I ran the same process but with a pressure bleeder this time and got the same results, fixed for 100ish miles. The original fluid looked bad and I thought I got most of it out, it could've been the wrong fluid. The codes; P25A2, C05B0-00, C2A1B. I can get them to clear but not for long. The C05B0 indicates a leak in the front circuit (which is bone dry) so I'm thinking of doing the bleed process on that front again today and I don't know if that's taboo to just do the front but at this point it seems like it's worth the try anyway. The new master cylinder/module unit is supposed to get here today. But now I'm pretty much convinced this install is over my head. I've called several shops and some mobile guys that I know but this thing is like radio active material, scary wise. I did get 2 local shops say they should be able to do it, one says he has the SPS2 programing capability. And with the battery disconnected is there supposed to be pedal resistance, mine is to the floor, then if I pump it I can get some resistance. I had a panic stop prior to this issue which may have contributed from what I read. And on the first attempt to bleed and hydraulic test the scanner listed things to look for and one was any gaps between the pad and rotors which I did notice on the RF corner and I removed the outer pad (where the gap was) cleaned it and the hardware and didn't see a gap after that but will re-check it. I read that if pushing the caliper pistons back then you're supposed to open the bleeder so as to not push fluid backwards into the abs module or it will damage it. If that's true then that's also a possibility from the previous owner having the brakes changed before I got it. I'm using an XTool ip500 scanner. Any suggestions, questions and comments welcome.

      Next Friday will be my 6 week point from my right knee replacement.  The surgeon says it will be fine if I choose to drive after this checkup.  I know I could drive now but best to do as my surgeon (and my wife) tell me.  Richard compared being 62 to 72.  I remember when I was in my early 60's I was experiencing slow but regular decline in my mobility.  Thanks to good medical support,  i continued to fight the speed and spread of this decline. During my 60's I worked on non-surgical methods and just when I turned 70, my orthopedic surgeon recommended joint replacements.  In a little over a year, I had one shoulder and both knees replaced.  This hasn't been a terribly fun experience, but worth the discomfort as my future mobility health trajectory has reversed.  It is a treat to now be watching my mobility. balance and confidence steadily improve!
