For 1990-2009 cars

The windshield wiper lever is located on the right side of the steering wheel.

Move the lever to control the windshield wipers.

(Off): Turns the windshield wipers off.
(Intermittent; Speed Sensitive Wipers): For intermittent or speed sensitive operation. The amount of delay time varies between wiping cycles due to the delay setting selected or the speed of the vehicle. As vehicle speed is increased or decreased, the wiper interval also increases or decreases.
(Delay): While the lever is in the intermittent position, turn the intermittent adjust band with this symbol on it up or down to select a shorter or longer delay between wiping cycles. To the left of the adjust band are bars, increasing in size from bottom to top, that indicate the frequency of the wipes. Smaller bars mean the wipers movement is less frequent. Larger bars mean the movement is more frequent.
(Low Speed): For steady wiping at low speed.
(High Speed): For wiping at high speed.
(Mist): Move the lever all the way down for a single wiping cycle. Hold it there until the windshield wipers start; then release. The wipers stop after one wiping cycle. Hold the lever down longer, for more wipe cycles.

Clear ice and snow from the wiper blades before using them to avoid damage.

If the wiper blades are frozen to the windshield, carefully loosen or thaw them. If the blades become damaged, get new blades or blade inserts.

Heavy snow or ice can overload your wiper motor. A circuit breaker will stop the motor until it cools. Clear away snow or ice to prevent an overload. If the motor gets stuck, turn the wipers off, clear away the snow or ice, and then turn the wipers back on.

As an added safety feature, if the wipers are on for more than 15 seconds, the vehicle's headlamps will turn on automatically. They will turn off 15 seconds after the wipers are turned off.
