2013 LS Radio/HVAC Failure Progression

[Capital]

Hi all. I’ve got a 2013 Camaro LS (non‑MyLink) and the factory radio/HVAC control module has basically reached end‑of‑life. Here’s the full progression in case anyone recognizes this pattern.

Early symptoms (intermittent):

• Radio would randomly shut off or reboot
  
• Static in the speakers that sometimes matched the turn signal
  
• Clock drifting
  
• CD ejecting on startup
  
• HVAC panel flashing while the radio tried to boot

As it got worse:

• Panel blinking constantly during startup (see link below)
  
• HVAC fan turning on/off in sync with the blinking
  
• Sometimes it would “settle down” after a few minutes and work normally
  
• Cold weather made the symptoms less severe
  
• Now that it’s hotter out (around 85°F), the symptoms are much worse and more frequent

Current state (basically failed):

• Radio won’t turn on at all
  
• Display stays dark
  
• Entire front panel blinks endlessly
  
• HVAC controls keep rebooting
  
• AC no longer gets fully cold
  
• Heat no longer gets fully hot
  
• Turn‑signal click sound is gone
  
• Seatbelt chime is gone

What still works:
Turn‑signal lights, BCM functions, and all mechanical HVAC components.

From what I can tell, the radio/HVAC faceplate module is stuck in a brownout/reboot loop — internal voltage regulators, timing crystal, and DSP are failing. Since this module also generates the turn‑signal click and chimes, losing those lines up with the rest of the failure.

Looking for confirmation from others who’ve had this exact failure and what replacement route you took (OEM, refurbished, or aftermarket - preferably not touchscreen).
