First you need a wiring diagram, free at http://www.bbbind.com/free_tsb.html Then you need a DVOM - digital volt ohm meter to test the circuit . Then if your not familiar with automotive electrical systems testing ,go on youtube an check out Electric Testing Techniques You Need to Know Also having a factory diagnostic trouble shooting chart would also be usefull . You could just start replacing parts , you mite get lucky . The wiper motor is a high fail part , so is the switch ..You could find the fuse is blown ! But fuse's don't usually blow without a reason . Short to ground , low resistance . ( high current flow) Also knowing how they work and what all is involved in making them work.
The Wiper/Washer System consists of the following components:
• Windshield wiper/washer switch
• Windshield wiper motor module
• Windshield wiper motor
• Windshield washer pump motor
• FRT/WPR/WSHR 25A fuse
Wiper/Washer System Operation
The windshield wiper motor module is part of the windshield wiper motor cover and controls wiper motor operation. The windshield wiper motor is a 2 speed motor and is operated at low speed in all modes except HIGH. The accessory voltage supply circuit to the windshield wiper motor assembly is used to operate the wiper motor in all of the low speed modes. The accessory voltage supply circuit to the windshield wiper/washer switch is used to supply the windshield wiper switch signal circuits and the wiper motor high speed circuit.
When the wiper/washer switch is in the LOW position voltage is supplied through a 24K ohm resistor within the switch to the windshield wiper switch signal 2 circuit, and accessory voltage is supplied to the windshield wiper switch signal 1 circuit. The reduced voltage from the wiper switch signal 2 circuit and accessory voltage from the wiper switch signal 1 circuit causes the wiper motor module to close the wiper motor accessory voltage supply circuit to the wiper motor low speed terminal.
Windshield wiper/washer system MIST operation is identical to LOW operation except that the MIST switch is a press and release type. When the wiper switch is moved to the MIST position and released, low speed wiper motor operation is started and will continue until 1 cycle is complete. If the wiper switch is moved to the MIST position and held, the windshield wiper motor will operate in the LOW mode until the switch is released.
Don't the wipers work in any mode ?

Let me know if you make it this far and i will send rest of diagnostic's
This can be due to slippage or looseness in the wiper arm fittings or the wiper motor spiral wheel assembly If there is noise when the wipers are put on , then pull up the wipers from the glass and see if they work. If so the nurlings are worn out and a metal shim on the nurlings which can be tightened can solve the issue
The wiper cam actuator the cam is made to prevent damage to the
motor by using a spring to allow it to slip if the wipers are stuck or frozen
to the wind shield the spring stretching causes the wipers to stop in the
middle of the window not hard to replace but does require you to do a timing
procedure it should come in the box if not ill give you the basics get the new
part remove both wiper arms careful the windshield is under the black plastic
and I've seen other break the windshield taking the wiper arms off a battery
post puller is the best way to remove , remove the cowl plastic piece you will
see the cam gold/silver in color remove the one torx head screw then install
new one rotate clockwise 2 times should spin freely then spin counter clockwise
should stop look at where it is touching this area should have a 4mm gap the
wiper motor has to be in the intermittent position prior to this turn key on
put wipers in intermittent let motor spin then when it stops shut the key off
then install cam. -------- Removal Procedure:Tools
Required:J 39232 Wiper Linkage Separator Remove the wiper
arms. Refer to Windshield Wiper Arm Replacement .
Remove the air inlet grille panel. Refer to Air Inlet Grille Panel Replacement
Remove the water shield.Remove the screw and the nut. Dissconnect the RH linkage assembly from the LH linkage assembly
with the J 39232 .
Remove the LH linkage assembly.Remove the screw from the wiper motor. Pull the wiper motor free from the slots of the bracket.Disconnect
the RH linkage assembly from the wiper motor with the J 39232 .Disconnect the
electrical connector from the wiper motor.
Installation Procedure:Tools Required:J 39529 Wiper Linkage Installer Connect the electrical connector to the wiper motor.Connect the RH
linkage assembly to the wiper motor with the J 39529 . Important: When installing the wiper motor, be sure that the crank
arm is in the innerwipe position. The crank arm drive pin must be engaged in
the cam pocket. Install the wiper
motor with two locator pads pressed into the slots of the bracket. Notice: Use the
correct fastener in the correct location. Replacement fasteners must be the
correct part number for that application. Fasteners requiring replacement or
fasteners requiring the use of thread locking compound or sealant are
identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems. for getting more

Water can enter and displace the grease in the wiper arm linkage ball joint where the wiper linkage attaches to the wiper motor linkage.
This can result in gradual wear over a period of time inside the joint that could lead to the separation of the wiper linkage assembly from the wiper motor linkage at the ball joint. A loss of windshield wiper function can result when this separation occurs.
To prevent grease from being washed out of the joint, the dealers will modify by adding a water diversion seal that will prevent water from entering the windshield wiper linkage ball joint area.
This is a common problem with Chevy Venture, Olds Silhouette, and Pontiac Montana. The mechanical wiper drive and parking cam assembly, if it's not broken, needs adjustment. The spring loaded stop arm should engage the vertical tab on the assembly mounting plate when the wiper motor reverses. See pic.
I will upload the instructions to fix this problem, if there is interest.
This has happened a couple of times on my 1999 Pontiac Montana. Here's what I did to fix. Open the hood. Remove the shield over the the wiper cam mechanism on the passengers side. This is easy to access. Road salts and other dust and dirt gets in there and causes the sticking problem. Spray WD-40 in between the parts. Get in there with that little red spray straw and saturate it good, flush junk out. Get in the car and try the wipers. If I remember, you might have to manually place that little knob or lever on top of the cam in the opposite position to get it to resync, but try it first. Be sure the wipers are off when you're spraying the WD-40 so you don't injur your hands. I've had to do this twice and it worked both times.
The problem is the cam assembly that sits on the motor shaft. It gets torqued out of position by snow or ice. When the motor reverses to park, the cam assembly should open as it is reversing, ( pin registering in top plate) and revolve with that pin being 180 degrees opposite of the slot it slides in when the wipers are wiping. On the bottom of the 3 plates, there is a spring loaded arm that will contact a stop, thus parking the wipers. One torx head screw holds the cam on; remove it; run the motor through a few cycles; hand park the wipers, reassemble with that top pin opposite of it's slot for normal operation. A small screwdriver can move the pin out of it's slot, and then you can rotate the plates to move it to position. I've had the best luck with the arm on the bottom just past its stop.
