(1) Depressed Park= Wipers go down low and disappear under the hood when turned off, double arm on drivers side. This style comes on cars with almost any option package. If your arms are missing just look at the drivers side wiper shaft that wiper arm connects to. Under that there is a pin to run the second arm on depressed park equipped cars.

(2) Exposed park= Wipers that will show above the hood when turned off, are silver in color and both sides are single arms (no double on the drivers side). These are generally found on lower cost, lesser optioned cars.
