The tachometer in this vehicle is working only intermittently and is getting
rather anoying. Is this an easy fix, any help is appreciated.
Been there and done that, first with my '91 and then with my '92.
The gauge face can warp slightly over time and apply friction to the tacho
shaft, preventing it working correctly. Removing the needle and carefully
winnowing out the hole to provide more clearance works. Sometimes the
mechanism itself stops working right, or the contact pins get loose, or
the tach drive module on the back of the instrument cluster stops working.
Just grab another cluster assembly from the wrecking yard; they take 2
minutes to remove and are all the same per type (basic analogue, deluxe
analogue with tach, electronic) '89-'95. Or just remove the tach needle
and live with it -- Some '91 Spirits came with manual transmissions, but
most with automatics, and a tach is totally unnecessary on an automatic
car.
