2001 Chevrolet Cavalier LS, 2.4 TSECTION Test 1: Wipers Inoperative In Any Mode
WARNING: This page is about a different car, the 2000 Chevrolet Corvette and 1999 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
  1. Disconnect wiper/washer switch 6-pin connector C219 at base of steering column. Turn ignition switch to RUN position. Using DVOM, measure voltage between ground and wiper/washer switch connector terminal "C" (Yellow wire leading toward instrument panel electrical center). If reading is 10-14 volts, go to step  3 . If reading is not 10-14 volts, go to next step.
  2. Check for open WSW fuse (25-amp) located in instrument panel electrical center. If fuse is okay, check for open in Yellow wire between wiper motor connector terminal "B" and instrument panel electrical center. If fuse is open, go to step  6 .
  3. Disconnect wiper motor connector. Turn ignition switch to RUN position. Turn wiper/washer switch to LOW position. Measure voltage between wiper motor connector terminal "B" (Yellow wire) and ground. See Fig 1 . If reading is 10-14 volts, go to next step. If reading is not 10-14 volts, repair open in Yellow wire between wiper motor connector terminal "B" and instrument panel electrical center. See WIRING DIAGRAMS  .
  4. Turn ignition switch to OFF position. Using ohmmeter, check for continuity between ground and wiper motor connector terminal "A" (Black wire). See Fig 1 . If resistance is less than 0.5 ohms, go to next step. If resistance is more than 0.5 ohms, repair open in Black wire between ground and wiper motor connector terminal "A". See WIRING DIAGRAMS  .
  5. Reconnect wiper motor connector. Connect 30-amp fused jumper between wiper/washer switch connector C219, terminals "B" (Gray wire) and "C" (Yellow wire). Connect an additional 30-amp fused jumper between wiper/washer switch connector terminals "A" (Dark Green wire) and "C" (Yellow wire). Turn ignition switch to RUN position. If wiper motor operates at low speed, replace wiper/washer switch. See STEERING COLUMN SWITCHES - CORVETTE article. If wiper motor does not operate at low speed, check wiper motor linkage for binding or damage. Repair as necessary. If wiper motor linkage is okay, replace wiper motor. See WIPER MOTOR  under REMOVAL & INSTALLATION.
  6. Disconnect wiper motor connector. Ensure wiper/washer switch connector C219 is disconnected. Remove WSW fuse (25-amp) from instrument panel electrical center. Using ohmmeter, check for continuity between ground and wiper/washer switch connector C219, terminal "C" (Yellow wire leading toward instrument panel electrical center). If continuity does not exist, go to next step. If continuity exists, check for short to ground in Yellow wire between wiper motor connector terminal "B" and instrument panel electrical center. See WIRING DIAGRAMS  .
  7. Reconnect wiper motor connector. Reconnect wiper/washer switch connector C219. Connect ammeter (0-30-amp) across WSW fuse terminals in instrument panel electrical center. Operate wiper motor. If amperage draw is 0-25 amps, go to next step. If amperage draw is more than 25 amps, check wiper motor linkage for binding or damage. Repair as necessary. If wiper motor linkage is okay, replace wiper motor. See WIPER MOTOR  under REMOVAL & INSTALLATION.
  8. Check Yellow wire between wiper motor connector terminal "B" and instrument panel electrical center for intermittent short to ground. See WIRING DIAGRAMS  . Replace WSW fuse (25-amp) and retest system.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
