RAM 1500 Truck 4WD V8-5.2L VIN Y (1997)
Ammeter Between Terminal L And Battery
1. Unplug the wire harness connector at the wiper motor. Remove the wiper arms and blades. Connect an ammeter between the battery and terminal
L on the motor. If the motor runs and the average ammeter reading is more than 6 amperes, go to Step 2. If the motor runs and the average
ammeter reading is less than 6 amperes, go to Step 3.
2. Check the wiper linkage and pivots for any obstructions. If there are no obstructions and the motor continues to draw more than 3 amperes, replace
the faulty wiper module assembly
3. Check the motor wire harness for a short between the high and low speed circuits. Connect a voltmeter or test lamp to the motor ground strap. Set
the wiper/washer switch in the Low position. Connect the other lead of the voltmeter or test lamp to terminal H of the motor wire harness
connector. If voltage is present, there is a short in the wire harness or the multi-function switch. If no voltage is present, go to Step 4.
4. Set the wiper/washer switch in the High position. Move the voltmeter or test lamp lead from terminal H to terminal L of the motor wire harness
connector. If voltage is present, there is a short in the wire harness or the multi-function switch.
Condition
-
The wiper motor will run at high speed, but not at low speed.
-
The wiper motor will run at low speed, but not at high speed.
Procedure
Test Lamp Between Terminal H And Ground
1. If the motor will not run on high speed, set the wiper/washer switch in the High position. Connect a test lamp between the motor wire harness
connector terminal H and a good ground. If the motor will not run on low speed, set the wiper/washer switch in the Low position. Connect a test
lamp between the motor wire harness connector terminal L and a good ground.
2. If the test lamp does not light at the motor terminal, there is an open in the wire harness or the multi-function switch. If the test lamp lights at the
motor terminal, replace the faulty wiper module assembly
Condition
-
The wiper motor will keep running with the wiper/washer switch in the Off position.
Procedure
One Jumper Wire Between Terminal P2 And L - And Jumper Wire Between Terminal P1 And B+
1. Unplug the wire harness connector at the motor. Connect a jumper wire from terminal P2 to terminal L of the wiper motor.
2. Connect a second jumper from terminal Pi to the battery If the motor runs to the park position and stops, the multi-function switch is faulty If the
motor keeps running and does not park, replace the faulty wiper module assembly
