Took off the four bolts that hold seat in place to be able to tilt it back and study the wiring and motors. There is a control box with a bunch of relays and separate connectors that feed all the motors. I found that if I rock the connectors back and forth I can get that seat tilt motor to operate just fine. But looking at the connectors, they look clean. So my theory is that the internal connections in the relay box might not be in very good condition. I cannot seem to get it to work without the wiggling. If I stop the wiggling, it stops working. Does this seem like I control box problem? Has anyone ever taken that box apart to clean or repair the inside?
