I got new switches and found that it worked reliably but was pretty lazy. I cleaned the old grease and gunk out of the cable, cable track, regulator and window track. I lubed the cable, cable track and reg with lithium spray grease and tri-flow. I used silicon spray lube in the window track. Then, just to be thorough, I took the cover off the motor and cleaned everything in there. It seemed like a lot of work at the time, but I'm sure it will work for 10-15 years or so before I have to look at it again.
