Use a multimeter to test the continuity of the wires and make sure that there is no open circuit. If you find any breaks or damage, repair or replace the wiring as necessary.

Step 3: Check the Switch

If the wiring is not the problem, the next step is to check the switch for the seat driver rear up function. Use your car’s manual to locate the switch and remove it from the circuit. Use a multimeter to test the switch for continuity and make sure that it is functioning properly. If the switch is faulty, replace it with a new one.
