370z roof won't move warning light on

KenB,

There are 8 small hydraulic rams in the top mechanism. Each one has a sail switch (read position switch) at its two positions, fully extended and fulled retracted. They tell the top computer when the ram has reached either end of its travel, the computer reads the info, and then starts its next part of the open/close operation.

In K4mik4ze's case, they discovered a broken/frayed wire at one of the sensor connections on the ram and corrected it.

Sadly, if the sensor had been at fault and needed replacing, since Nissan does not sell rams or sail switches as individual parts ... the only solution would have been to replace the entire top mechanism, .... to the tune of upwards of $12 000 dollars.

Its crazy expensive, but it makes more sense from Nissan's point of view to replace an entire top, motor, computer, cloth, frame and hydraulic system as a one piece item, to ensure a one time fix with no call backs. Its sort of like ... they'll replace a sticking brake caliper with a new one, rather than take the old on apart, clean it up, lube it, install new seals and reinstall it.

They make more money on the parts, hopefully spend less time on labour, and should have less call backs and complaints.
