Frequently asked questions

What does the MUC3025 window regulator do?

The MUC3025 window regulator is the left-hand front door mechanism that raises and lowers the window glass on the Defender. It mounts inside the door shell and carries the glass on its lift arms, turning winder-handle rotation into vertical travel of the glass.

Is the MUC3025 regulator for the left or right door?

The MUC3025 regulator is the left-hand (LH) front door unit. Fit it to the nearside front door. The opposite right-hand door uses its own mirror-image regulator, so check which side you need before ordering to avoid a wrong-side part.

Which Defender models does this window regulator fit?

The MUC3025 window regulator fits the Land Rover Defender 90 and 110 from 1987 to 2006, up to VIN (V)LA932528, left-hand front door. Confirm your chassis number against this break, since later doors use a different mechanism.

Can the window regulator be fitted at home?

Fitting the window regulator is typically a DIY job for a confident home mechanic. It usually means removing the door casing and trim to reach the mechanism inside the door, then transferring the glass onto the new regulator. Basic hand tools are normally all that's needed.
