Just spent and enjoyable? weekend working on the Tipo tailgate. original problem was sudden failure of rear wiper when my wife took the car out last week. Traced and checked everything from fuse and switch backwards and concluded that wiper motor is to blame. Having also repaired wires to heated rear screen en route (just about severed in trunking between body and hatch), took off cover panel under hatch and found that the catch fixing bolt on the n/s single bolt side had come adrift (again). The captive nut has pulled right out of the resin material leaving a nasty large hole. This had obviously happened originally before I go the car but various attempts to fix it with adhesive have failed.

Decided to try a permanent fix with a bit of tricky 'keyhole surgery' and ended up drilling 2 largish holes either side of fixing point so I could wiggle through an M6 bolt, large flat washer and spring washer from the innards of the hatch panel. Also modified the plastic cover panel so it fits without having to undo all the bolts. Hatch opening button now fixed directly to mounting on frame bracing which seems more secure anyway. Anyway, much relieved to have a secure boot again. Worst part has been working at top of line of vision wearing varifocal lenses!

Can't get the wiper to budge, even with 12v directly applied and also no return current through the S terminal so guess motor is faulty. I see that Ricambio still list a brand new one for sale so will probably go down this route, unless anyone has other advice on where the problem lies.

Yes, the tendency of the nuts to pull out of the resin is a pain. But this sounds like a good fix. The weight of the boot doesn't help. If you have eliminated your wife as the cause of the wiper problem ;-) then a motor sounds likely particularly if water got in there at some stage.

I had a similar problem some years ago and tried everything to fix it before finally giving up and running it from a separate switch.

I've got a spare rear wiper motor...

Thanks for offer but have just found a spare among my collection of bits and pieces of wiper parts . Will try this first but get back to you if I need another.

Pleased to say wiper is now working perfectly with new motor. Have sealed all round opening to try to stop water getting in. Thanks to all for advice, much appreciated as always!

Great news!
