Is your Jeep's AC blowing hot when you want cold, or vice versa? The problem might be a faulty blend door actuator. This VIPCAR replacement actuator (part #604-020) is designed to fit various Jeep models: the 1998-2001 Cherokee (XJ), 1999-2006 Wrangler (TJ), and 1999-2006 TJ series. It directly replaces OEM numbers like 5013741AA, 5170954AA, and F04055. Made with a redesigned housing and durable internal components to handle vibration and wear better than some cheap alternatives. Installation is a moderate DIY job if you're handy—usually located behind the dashboard. Important: After installing, you'll need to recalibrate the HVAC system (check your Jeep forum or manual for the simple procedure). Always verify your vehicle's exact year, model, and the actuator's location before buying. Comes with a 2-year unlimited mileage warranty and solid customer support. Get your climate control working smoothly again!
