How to Diagnose and Replace a Mercury Window Regulator
If the windows in your vehicle are broken and will not move down or up, it’s likely that there’s something wrong with your Mercury window regulator system. The window regulator is responsible for adjusting the height of the windows. Most updated Mercury vehicles have automatic systems for making these adjustments; the Mercury Marine window regulator, for instance, is based on an electrical circuit and is operated by several buttons in the interior of the car. Older versions of Mercury vehicles have manual systems that are operated by a turn knob on the inside of each of the doors of the car. If your electrically powered window regulator seems to be broken, you’ll need to do a Mercury automatic window repair in order to properly fix the problem.
Tools and Materials Needed:
You’ll need the following tools and materials in order to complete this project:
- Screwdrivers of various sizes
- Volt meter
- Prying tool
- Replacement Mercury window regulator
Step 1 – Diagnose the Problem
Begin by assessing which windows are broken. If all of the windows in the car are nonfunctional, it’s likely that there’s an electrical circuit shortage or a blown fuse in the motor of your regulator. These problems can often be remedied by replacing individual components and not the entire regulator system.
Listen to see if you can hear any motor sounds when you manipulate the controls for the window. If you hear any noises coming from inside of the vehicle door, it’s probably that there’s power flowing to the system but that something is out of alignment.
Step 2 – Access the Regulator by Removing the Panel
Remove the screws that attach the plastic car door panel to the inside of the metal door. Place the screws in a safe, separate place. Use the prying tool to carefully remove the door panel from the door itself, exposing the regulator system underneath.
Step 3 – Inspect the Regulator and Check for Voltage
Visually examine the regulator for signs of damage. Problems may include broken connections, blown out wires or other similar signs. Replace any damaged components that you find. If you see nothing, use the volt meter to check and make sure that power is flowing properly to the circuit.
Step 4 – Replace the Regulator If Needed
If you can find no other reason that the system isn’t working, replace the regulator by removing the old one and following the instructions that come with the new system. Turn off electricity to the car before you begin. Be sure to check that the regulator has power and works properly before you reattach the car door panel, as this could save you time in your project.
If you have any other questions about the process of diagnosing and replacing a Mercury window regulator, consult with a Mercury specialist or a mechanic for more information.
