I've had very good results with a contact cleaning and preserving 
product called DeoxIT from Caig Laboratories.   This is the first thing 
I try on electrical and electronic connectors, switches, relay contacts, 
light bulb sockets, computer edge connectors, etc.  Given the plethora 
of such connectors on modern automobiles, this is a good thing to have 
handy and try first before resorting to more extreme and potentially 
expensive diagnosis and repair.  Its available at electronic shops or 
from the Caig website at www.caig.com.  Contains no CFCs and doesn't eat 
or stain plastics or leave much messy residue - overspray pretty much 
evaporates away, so you can hose things down that you can't get to 
easily, for example the turn signal contacts in the steering column.  
Comes with a flexible plastic tube about 5" long that you can attach to 
the aerosol nozzle to get it into hard to reach places.  This is how I 
use it most of the time.  Highly recommended.  No, I don't work for them 
or gain anything by this recommendation - just a very satisfied 
customer.  Cheers and happy motoring.
