What are the reasons for the inability to adjust the power seat forward and backward?
2 Answers
Power seat forward and backward adjustment failure may be due to a damaged adjustment switch, burned-out adjustment motor, or circuit malfunction. Many cars are equipped with power-adjustable seats, which have internal electric adjustment mechanisms. If these mechanisms are damaged, the seat will not be adjustable. More details are as follows: 1. Generally, power seats have two common issues: one is the seat being completely unresponsive, and the other is the seat not being adjustable in a certain direction. 2. The inability to adjust the seat in a certain direction is mainly caused by motor damage or switch short circuits. First, check if the fuse is blown. If there is no issue with the fuse, inspect the wiring for faults, then check the power seat switch or the seat mechanism for problems, and finally, check if there are any broken wires.
Electric seat front/rear adjustment failure is a common issue, and I often enjoy troubleshooting minor vehicle problems. The most frequent cause is a blown fuse, located in the fuse box under the driver's seat—just use pliers to pull it out and check if it's burnt black. Another common issue is poor contact in the switch button, possibly due to dust or wear; if pressing it a few times yields no response, suspect the switch. For more serious problems, motor drive failures like overload burnout or seized bearings can occur, which are costlier to repair. I’ve also heard fellow car enthusiasts mention track blockage, where dust buildup or insufficient lubrication on the tracks can cause issues—try manually pushing the seat to see if it moves. In any case, avoid forcing the mechanism to prevent further damage, and start with the simplest checks first.
