Same problem here with my 2000. If you look closely, the contacts
build up a slight amount of corrosion. The metal starts looking dull.
I'd guess this is the result of the small electrical currents that
pass through them on contact. I carry a hard eraser in the glove box
and when it happens (about every 3 months), I just rub the contact
down with the eraser. So far it's worked everytime.
