From the shop
Climate control head units on the 2003–2006 Sierra and Silverado handle temperature blend, fan speed, and mode selection. When the display dims, buttons stick, or knobs lose detent feel, the whole unit usually needs replacement. This one is OEM, tested — all knobs, buttons, and display functional. Cleaned. Direct fit for both makes and model years listed. — Hubes
