In this step-by-step guide, you will find the procedure on how to replace a window regulator and motor on just about any Volvo. There may be some differences, depending on the model but the general instructions are still the same.
What you will need
- Disconnect the negative battery terminal. Your car will have the battery under the carpet in the trunk or in the engine bay on the driver's side.
- The first step is to remove the door paneling. In most cases, it will be held by push-pin clips. To release them, just push in the center part, after that you can take out the whole pin.
- Using a thin flat screwdriver, remove a small tab inside the door grab handle.
- Undo a retaining screw using a T25 Torx screwdriver.
- Use a pry tool to pop out the window switch. Disconnect the window switch by pushing the tab on the connector and pulling it out
- Carefully pull the door panel upwards, raising it from the window ledge and the lock button.
- Unclip the two clips that hold the door handle release cable and pull out the cable.
- Using a razor blade, remove the insulation by cutting through the foam-like glue. Be careful not to tear the insulation.
- Depending on a model, the regulator mechanism is connected to window fixture either by sliding blocks or rivets.
- Don't disconnect the door airbag wires. Temporarily connect the battery negative terminal to operate the window. Lower the window into the position where the sliding block or rivet is accessible. Disconnect the negative battery terminal.
- In case of sliding block, pull off the retaining clip with a screwdriver, and pull out the regulator lever. In case that rivets are used, you need to drill them out.
- Repeat the last two steps for releasing the second sliding block.
- Manually push the window up, and secure it into place with several pieces of tape.
- Disconnect the electrical motor. You will need to push the tab on the connector with a screwdriver to unlock it.
- Using an appropriate size drill bit (~6mm diameter), drill out the rivet heads that hold the window regulator in place.
- Undo the 10mm nut at the top of the regulator carefully rotate and wiggle the regulator until you are able to get it out.
- If replacing only the window regulator or window motor, remove three Torx screws then remove the window motor from the regulator.
- Reinstall the new windows regulator in reverse order of removal.
- Correctly position the regulator, and install new appropriately sized rivets using a rivet gun.
- To reinstall the push-pin clips, push the center pin all the way out. After inserting it into place, push the center-pin in until it is flattened.
Sliding blocks are a known weak point. If the regulator on your car uses these, they should be replaced as well.
These instructions apply to multiple Volvo vehicles including XC70, V70, S60, S40, V40, V50, XC60, XC90, S60, S70, S80, C30 and 240.
