Frequently asked questions

What does the RTC3821 window motor do?

The RTC3821 is the left-hand front door window motor. It drives the regulator mechanism to raise and lower the front side glass, mounting inside the door cavity and connecting to the regulator track via the drive arm. It fits Discovery 1 and Range Rover Classic with electric front windows.

Which side and door does the RTC3821 operate?

The RTC3821 operates the left-hand front door window on Discovery 1 and Range Rover Classic. It sits inside the front door cavity, driving the regulator that moves the front glass. The matching right-hand motor is a separate part, so check which side you need.

How do I confirm the RTC3821 fits my vehicle?

Check your VIN. The RTC3821 fits Discovery 1 (1989-1998) with power front windows up to VIN MA137189, and Range Rover Classic 2-door and 4-door Station Wagon up to VIN HA610293. Later vehicles used a different motor, so confirm before ordering.

Can the RTC3821 window motor be fitted at home?

Fitting the RTC3821 typically means removing the door trim card to reach the regulator inside the front door. It's a manageable DIY job with basic hand tools and trim removal tools, though the glass usually needs supporting while the motor is unbolted from the regulator.
