2. Inspect and Replace the Fuse

Step 1: Locate the fuse box under the dashboard or in the engine compartment.
Step 2: Remove the fuse for the power windows using a fuse puller or pliers.
Step 3: Inspect the fuse for continuity; if it is blown, replace it with a fuse of the same amperage.

3. Test and Replace the Power Window Switch

Step 1: Remove the door panel using a socket set to access the power window switch.
Step 2: Disconnect the switch harness and test with a multimeter for continuity when switched on.
Step 3: If the switch is faulty, replace it with a new one and reassemble the door panel.

4. Test and Replace Window Motor/Regulator

Step 1: If the switch is fine, check the window motor by applying direct power from a battery to it.
Step 2: If the motor does not operate, remove it from the window regulator assembly.
Step 3: Replace the faulty motor or the entire regulator if necessary, ensuring all connections are secure.
