Hi,
Is it possible to get to the wiper linkages through the rear door panel? It's started going slower and stopping , and the 3-in-1 isn't fixing it as fast as usual from the outside... ! Thought I'd try regreasing the internal gubbins as well.
Ta
PS - How much to get drop link bushes replaced ?

Don't know this specific wiper, but have had several Fiat wiper assys apart. Most have a snap-ring/circlip retainer, stainless washer, nitrile O-ring, on the outer end of the wiper shaft, inboard of the splines that hold the wiper arm. If with age water gets past the O-ring, big problem, it's an iron shaft in a diecast tube, a poor electrochemical combination, it corrodes and greadually freezes solid. If you get the whole assy off be prepared for a bit of dismantling, and note which thin stainless thrust washers go where. It's not too difficult a job, bet it takes a fair bit of time. Fiat self parking slip ring/finger assys may need careful adjustment of the phosphor bronze fingers if it doesn't wipe, or park, when it should. For the iron wiper shaft I re-lubricate with Castrol Heavy (LM seemed a bit on the thin side) with some Silicone MS4 for its water repellent properties just around the O-ring washer bit. You may also need an assorted O-ring kit, if the O-ring is aged or worn. Most problems have been with the front wipers, that get driving rain, at 70mph or so, trying to force water past the seal, so after about 5-10 yrs they start to develop this problem.
