✓MATERIAL CONSTRUCTION – Manufactured from automotive-grade ABS delivering long-term durability in elevated temperature conditions. Each AC control panel undergoes functional testing — button response, knob rotation, and electrical continuity verified. The housing stands up to spills, extreme temps from -40°F to 185°F, and heavy daily use
✓FULL HVAC FUNCTIONALITY - Stay cool on hot summer days with responsive AC cooling, while precisely controlling temperature, fan speed, airflow mode, internal/external circulation, and defrosting. Supports rear window defroster on vehicles originally equipped — the defogger button lights up and activates as intended. HVAC control module designed to restore factory climate control functions for year-round driving comfort.
✓PLUG-AND-PLAY INSTALLATION – remove old unit, disconnect wiring harness, and connect to this new module.[Note: Mounting screws are not included — reuse original screws]. Installation typically takes 10-15 minutes for DIY users.
