FAQ

Q: Why is my power seat not working?

A: There are several reasons why your power seat may not be working. The first thing to check is the fuse. If the fuse is blown, replace it with one of the same amperage. If the fuse is good, check the wiring for any damage or loose connections. If the wiring is good, the problem may be with the power seat switch, seat position sensor, or memory seat module. You may need to have these components tested and replaced if necessary.

Q: How do I adjust the power seat?

A: To adjust the power seat, use the buttons on the power seat switch. The first button is for forward/backward adjustment, the second is for up/down adjustment, and the third is for tilt forward/backward adjustment. To save a seat position in memory, press the fourth button and then press one of the numbered memory buttons. To recall a saved seat position, press the memory button with the corresponding number.

Q: Can I install a power seat in my Silverado that did not come with one?

A: Yes, it is possible to install a power seat in a Silverado that did not come with one. However, this can be a complicated and expensive process. You will need to purchase a power seat and all of the necessary wiring and components. You may also need to modify the seat mounts and the interior trim of your truck. It is best to consult with a professional mechanic or installer to determine if this is a feasible and cost-effective option for your specific truck.

Q: What should I do if my power seat is stuck or won’t move?

A: If your power seat is stuck or won’t move, first check the wiring and fuses as described above. If these are not the problem, the issue may be with the seat motors or gears. You may need to have these components replaced. It is also possible that the seat track or frame is bent or damaged, in which case you will need to have the seat removed and inspected by a professional mechanic or installer.

Q: Can I disable the power seat and use a manual seat instead?

A: Yes, it is possible to replace the power seat with a manual seat. However, this can be a difficult and time-consuming process.
