So I've been working like a madman on my 240z and replaced the wiper motor AND linkage (which I thought was the issue). The thing is this: Before installation, the motor works great and I can even turn the linkages freely by hand without issue. Once installed, the wipers won't move. This isn't the standard "wet glass needed" situation either. Without wipers on, the pegs don't rotate. Figured I'd ask for some help. The connections are all good, wiring is solid and the battery is fully charged. Thanks for the help!! Chris

Hello. I've searched the archives and cannot find an answer, and perhaps this is such a basic question it's just not there. I have the usual "my wipers don't work but my motor does" issue in my 1975 Z. I have pulled the linkage, cleaned them, lubbed them, but is there something else. I have attached a jpg of the pivot points. Is there something on this that can be disassembled and cleaned? I did find a previous post, and I'm hoping you can tell me he is talking about my issue: Previous post begins here: Then before you put everything back, carefully remove the round clip at the shaft that holds the shaft through the shaft holder. This can easily be pried up and out of its grove, don't bend it! Then ease it off the shaft, I did it by pushing down on the shaft and letting the shaft holder push it off. You should now be able to remove the shaft from inside the shaft holder. Look inside the shaft holder. You should see that there are two bushings inside of it, with about a 3/8" gap between the upper and lower bushing. Clean these off with a soft wire brush, enough to remove the rust, but not enough to mar or remove material. Also inspect the shaft for any wear. If the shaft is worn badly, you need to find a replacement set of shafts, it's easier to find the whole linkage assy at a boneyard. If the bushings are worn such that they allow the shaft to have play, then I suggest you replace the bushings. You want the shaft to spin freely, but not have any side to side play. If you feel you won't be able to find replacement bushings, then get a new set of linkages. When you're ready to reassemble, make sure that the gap between the bushings gets packed with some white grease. This is the "reservoir" that eventually gets used up, and it's what the rubber boots are supposed to protect. Then put the circle ring back on. Your shaft holders should be able to spin relatively freely around the shaft. If they do, and your arm linkages have easy spin also, you should get the same kind of speed out of your wipers as when the car was new. -- Previous post ends. I am very grateful for whatever help/advice anyone can offer. This windshield wiper issue is the last thing on my list of things to fix (list supplied by the ever-helpful New York state inspectors). Thanks,
