I have a 1977 280z and when I turn on the wipers, it sounds like they're about to croak. It's like they're using all of their effort just to try to wipe the windshield. I've never seen wipers move that slow. Do I need a new motor or is that just how those models are?

007, sounds like you need to do some maintence. I think that if you pulled the motar and linkages and cleaned and lubed everything things may be ok . You have nothing to loose , if you continue to use them and they are dragging you most likely will burn out the motor and have to pull it any way. I did mine about a month ago and improved the function about 30% Good luck Gary Portland Oregon.

Luggnut has good advise. Search the archives, I think some info has been posted on maintaining the wiper motor. Have you ever used "Rain-X"? Regular use of Rain-X will repel water from your windshield.

I just recently removed, cleaned and replaced my wiper set up, with little improvement as far as speed. Yes they operate better but the difference between slow and high speed needs to be evaluated by counting and stop watch.

Some one here also posted the # of RPM's the wiper motor should be working at, but couldn't find it.

By the way, I agree with "Rain-X" for the EXTERIOR of your windows, it really REALLY makes a difference on how much and continuously you have to use the wipers.

HOWEVER, and this is important, DO NOT USE THE ANTI-FOG RAIN-X on the inside of your windows. This stuff will ACTUALLY FOG your windows PERMANENTLY. There is no fix, you will regret it for the rest of the time you own the car. Simply put, throw this stuff away.

I put some on my Acura and after half a dozen attempts at removing the stuff (since the 3 attempts at "polishing" per the instructions" did NOTHING, didn't get clearer, just stayed the same) using Windex, Automotive Glass Cleaner, Alcohol, Mineral Spirits, and lastly Acrylic Thinner finally was HAPPY that I got a rock chip requiring the windshield be replaced. I still have the crud on the side and rear window, now just wondering if I can get one of the neighbor kids with a BB gun........

has anyone replaced the crappy Z motor with one from a different car? I wish I knew of a car that would make an easy conversion....
