Defrost button no longer lights up

2019 Silverado LD, legacy body. Basically it's the same as a 2018.

 

My defrost button began flickering at night and now it doesn't light up at all. The defrost works fine and the little yellow light showing the defrost is on works fine, but the defrost symbol on the button just doesn't light up at night. Everything else on the panel is lit. 

 

Is there an (old school) light bulb behind that button? If so, how do I get to it? Or maybe the button itself needs to be replaced? Does the button just pop out or do I have to pull the face of the HVAC instrument cluster?

Thanks,

Joe

After further research I've found that basically we would have to replace that whole HVAC panel.

I've read that the panel costs about $130. Some say it was not a difficult job. 

For me, I'll just live with it. Everything does work. Only one button is not back-lit.

How much was the panel?. Do you access the the r and r from the front? Or do you have to lay on your head?

Thinking I paid around $130.00 on Amazon for a new unit.

You take the silver trim panel off, starting at the bottom, disconnect the heated seat switches, then remove the radio screen and HVAC control as one unit. Swap the HVAC control, then reverse steps to put back together. 

There are a few videos floating around that shows how to do it, will make more sense if you see it done.

      I could be interested if they axed cylinder deactivation and at least have a button for stop start. I’m sure the HP numbers will be higher. I would want a longer warranty to help build confidence. I’m a less is more guy as I get older. A V-8 work truck model would be my choice. I know a few outfitters for custom additions I prefer.

      2027 GMC Sierra: Official Discussion

      It's official. GMC pulled the covers off the next-gen 2027 Sierra 1500, and we got the first official look. Full breakdown here: https://www.gm-trucks.com/next-gen-2027-gmc-sierra-1500-v8-trim-changes/   The quick hits: SLE and SLT are dead. The new core retail trim is just called "Elevation". Two new V8s, a 5.7L and a 6.6L built with high-performance Corvette architecture roots. No horsepower or torque numbers yet. The 2.7 TurboMax finally ditches the old gearbox and gets the 10-speed automatic. AT4X moves to larger standard 35-inch tires with front and rear e-lockers, Multimatic DSSV dampers, and heavy-duty Jounce Control Dampers. Over 60 inches of combined display on Denali Ultimate and AT4X, complete with a motorized articulating center screen and an adaptive passenger screen. Seven simplified trims across the entire model line to clean up ordering confusion.   So let's get into it: New 5.7L and 6.6L gas V8s with custom active exhaust tuning and a Corvette connection. Is this the exact engine lineup half-ton traditionalists have been begging for? Purging the iconic SLE and SLT names after all these years to lean entirely on Elevation as the high-volume core. Bold move, or a mistake? That motorized articulating 16.3-inch screen that slides up to reveal a hidden dashboard vault. Awesome mechanical theater, or does it make you nervous about long-term durability? Physically lowering the headlamps in the front fascia to improve road courtesy and stop blinding oncoming traffic. Smart real-world engineering, or does it hurt the truck's aggressive stance? What trim are you putting your name down for on day one? Drop your first impressions below.

      My overnight hospital stay turned into five.  I developed a post operative fever and an erratic  heart rate.  A blood clot in the lungs was the culprit.  This is apparently a common post surgical complication and easily remedied.   I was the youngest in a four bed ward and a Doctor with a Geriatric specialization was in charge of my care.  All of the nurses were good and some were outstanding at dealing with old people.  It was very evident that my age triggered a different level of care!  My advice to any senior going for a hospital stay is to have a trusted family member advocate visible.  If not, you will still be well cared for, but you may discover that your voice  isn't as strong as it once was!
