The power control that moves the tilts the seat upward (the top part with headrest attached) stopped working. The control the moves the seat forward and backward is fine, and so is the one that tilts the seat backwards. How do i fix this? I got a system installed (new headunit, subs, amps speakers) about 2 weeks ago, I never noticed the seat not working till now. Do you think this has something to do with it? Please help. Thank you.

 

fuse maybe? probably something really basic like that because ive never heard of the power seats failing
