I am a new 79 Elky ower and notice the right power window works
but makes a terrible grinding noise at up/down stop. This sounds
like a common problem that has been solved by others. Some
help will be appreciated.

Also, noticed it is very hard to unlock the car with the key. I fear
breaking the key in the lock. What's the best way to lube the
locks? Makes me appreciate the key fobs in the newer cars. HiHI

Use some GRAPITE LUBE in the key locks. Not sure on the window problem.
