This guide will show you how I repaired my Delorean electric window regulators. My regulators hadn't worked in several years and I decided to attempt to repair them before ordering new ones. Luckily it worked and I saved myself hundreds of pounds.

First try your windows to establish that it isn't the switch that is broken. With the ignition on press the window switch and the lights should dim on the centre heater console. If the lights don't dim then the switch could be broken or maybe even a lose wire. If it does dim when the switch is pressed proceed below.

First remove the two screws that secure the motor to the regulator.

Once the two screws are removed hold the plastic block connector for the wires and pull the motor case off.

You will see that motor outer case has corrosion on the magnets. This will need to be removed.

The motor armature also has corrosion and needs to be cleaned.

Use electric contact cleaner spray and a tiny grinder to clean the corrosion off.

Use the motor to remove the long spring regulator mechanism by holding the window up switch down. If the motor won't work you will have to rotate the motor by hand with the motor case off. Then clean the spring and re-grease it.

My regulator was still not operating smoothly and problem seemed to be inside the sealed cog mechanism. To avoid damaging the plastic case I decided to drill a small hole to gain access.

I then used this hole to flush the gears with WD-40 and spray grease.

After flushing with WD-40, success !, my regulator started to work very smoothly. The only other problem was my regulator had a small crack on the plastic elbow.

I decided to use epoxy glue and cable ties to make the plastic elbow stronger.
