I'm hoping someone can help me. I have an 87 GN and the power seat just stopped moving forward and back. It moves up/down, tilts. Just not back and forth. There is no clicking sounds or anything when I hit the switch, just nothing. Does anyone have an idea what it could be or how I can test if the motor or switch is bad? I'm a beginner working on this car, only ever worked on late 60's cars. The seat is all the way up and only my girlfriend fits in it to drive it. Please help.....
