the plastic nozzles on the hood of the contour must be cheap the dealer sent my contour our as it needed some repaint from sitting in the lot and had some marks on it.. the hood area had to be repainted.. the body shop guys brought it back to the dealer when i was there....... they they went the parts dept. and bought two nozzles as they broke them when taking them off to paint the hood.......
even cleaning with a pin might not help... the hole might be too enlarged and will not make the stream of water shoot out enough..... think of it this way:
you got a garden hose.. the tip is plugged up so you dont get any water.... you dig it out and the water comes out and falls to the ground.... or you could put your finger on the end of it and you get a nice big squirt...... thats might be what you need... a smaller hole in the end... a new nozzle.....
