Windshield Wiper Arm Jamming!
I have parked it at the extended position then popped the cover off the arm and lubed it. but after a while it is back to slooow again. Is there any particular type of lube I should use on this??
This may help, sorry, I've never done it myself though mine is getting pokey now too.

IS WD40 Safe to use? i dont think WD40 is a silicon lubricant..
and the guide does not even relate to my wiper system
