Maybe a loose ground. Do you have an aftermarket stereo? I still have some issues from the previous owners install.

How many miles on the car? If it's up in the 50k's then it's most likely the pulleys and belt just needs to be changed.

The belt has a recommended service life of 30K. I tried to go 60k but it was looking pretty sorry at 58K and I replaced it. So, try a new belt.

pulley has a bearing in it no? then it wears with time and needs to be replaced. spraying it will only mask the problem
