Mike,

The headlight wiper itself is covered by a plastic cap on the motor shaft area. You flip the cap up and will see the nut that hold the wiper to the motor shaft. You unscrew the nut and use a piler to pull the wiper arm off the motor shaft and then disconnect the washer hose from the wiper. After that, you can pull the trim plastic under the headlight assembly off starting from the inner part of the trim (from the side near the condensor/radiator). You must pull the plastic trim out carefully, bit by bit. Once the plastic trim is out (passenger side), you should be able to see the check valve for the headlight wiper (gray in color).

Hope this help.
