The problem - rear wiper runs an odd cycle and won't stop in the same place twice. Also won't run a single sweep wipe - keeps going through the 4 wipes cycle at ignition on and on steering column lever push.
I have stripped and cleaned the rear wiper motor (what a lot of rusty muck!) replaced the plastic wheel, and refilled with grease (I have used silicone grease on recommendation but it seems very thick - maybe white lithium would have been better..?).
The one problem was on reassembly I had a few tries to get the arm teeth after the wheel assembly (not the motor or wheel teeth) to mesh correctly in the right position for a full sweep.
Put the motor back in, popped the wiper arm back on the spline in the right position - but now it will only sweep a cycle of 4 times and never stops in the same place twice. The sweep is the right length and it sweeps the right area of screen - but its cycle does not stay the same exact length..
Should I just replace the motor? Or could it be the relay?
It was working ok until the plastic cog wheel finally gave up.
