Wiper/washer System Hyundai Elantra I

DESCRIPTION & OPERATION

The wiper/washer system uses a 2-speed wiper motor. Intermittent wiper cycle is standard equipment. Front washer systems are used on all models. Rear wiper/washer systems are available on Excel mod-els. An electric washer pump is mounted under fluid reservoirs.

WIPER ARM ADJUSTMENT

Mount wiper arm and blade assembly onto pivot shaft so the horizon-tal wiper blade is 1.2" (30 mm) above lower window trim molding in park position. On Elantra and Scoupe, the driver's side wiper blade should be 2.0" (50 mm) above lower window trim molding in park position.

Elantra

1. Unplug wiper motor harness connector. Using 2 jumper wires, connect battery positive to wiper motor connector terminalNo. 5 and connect battery negative to terminal No. 3. (Scheme 1) Wiper motor should run at low speed.
2. Connect battery positive to wiper motor connector terminal No. 6 and connect battery negative to terminal No. 3. Wiper motor should run at high speed.
3. To check wiper automatic parking, operate wiper motor at low speed as described in step 1). Stop motor operation by disconnecting battery positive wire at terminal No. 5. Using jumper wire, connect terminals No. 5 and 2. Connect positive wire to terminal No. 1. Wiper motor should run, then stop at park position.
4. If wiper motor fails any of these tests, replace wiper motor assembly. If wiper motor operates as described, but does not operate from switch, check multifunction switch continuity and check wiring for open circuits. If switch and wiring are okay, replace Time and Alarm Control Unit (TACU).

1. Unplug wiper motor harness connector. Using 2 jumper wires, connect battery positive to wiper motor connector terminalNo. 1 and connect battery negative to terminal No. 5. (Scheme 2) Wiper motor should run at low speed.
2. Connect battery positive to wiper motor connector terminal No. 1 and connect battery negative to terminal No. 2. Wiper motor should run at high speed.
3. To check wiper automatic parking, operate wiper motor at low speed as described in step 1). Stop motor operation by disconnecting battery negative wire at terminal No. 5, and then connect wire to terminal No. 3. Using another jumper wire, connect terminals No. 5 and 6. Wiper motor should run, then stop at park position.
4. If wiper motor fails any of these tests, replace wiper motor assembly. If wiper motor operates as described, but does not operate from switch, check multifunction switch continuity and check wiring for open circuits. If switch and wiring are okay, replace Time and Alarm Control Unit (TACU).

2. Connect battery positive to wiper motor connector terminal No. 1 and connect battery negative to terminal No. 6. Wiper motor should run at high speed.
3. To check wiper automatic parking, operate wiper motor at low speed as described in step 1). Stop motor operation by disconnecting battery negative wire at terminal No. 5, and then connect wire to terminal No. 3. Using another jumper wire, connect terminals No. 5 and 2. Wiper motor should run, then stop at park position.
4. If wiper motor fails any of these tests, replace wiper motor assembly. If wiper motor operates as described, but does not operate from switch, check multifunction switch continuity and check wiring for open circuits. If switch and wiring are okay, replace Time and Alarm Control Unit (TACU) on Scoupe, or Electronic Time and Alarm Control System unit (ETACS) on Sonata.

FRONT WIPER/WASHER SWITCH TEST

1. Wiper/washer switch is incorporated within multifunction switch, mounted on steering column. Test continuity of wiper switch circuits with switch in position indicated in table. See «WIPER/WASHER SWITCH CONTINUITY TEST»(/hyundai/elantra/i-1990-1995/remont/wiperwasher-systems/#wiperwasher-system).
2. Ensure continuity exists between terminals listed. Check connector and terminal cavity identification. (Scheme 3), (Scheme 4), (Scheme 5) or (Scheme 6). For terminal descriptions, See STEERING COLUMN SWITCHES article in the ACCESSORIES/SAFETY EQUIPMENT Section.

WIPER/WASHER SWITCH CONTINUITY TEST (1)

WASHER PUMP MOTOR TEST

Disconnect harness connector and washer hose at pump. Ensure reservoir has some clean water in it before running pump. Attach jumper lead from battery positive to terminal No. 2 (Blue/Yellow wire) of washer motor connector. Attach jumper from battery negative to terminal No. 1 (Light Green or Blue wire) of washer motor connector. Washer motor should operate. Replace as required. If washer pump does not operate, check for restriction in hose and/or nozzle, and/or check for open in wiring circuit.

REAR WIPER MOTOR TEST

Remove connector from wiper motor. Attach jumper lead from battery positive to terminal No. 1 of wiper motor connector. (Scheme 7) Attach jumper from battery negative to terminal No. 4 of wiper motor connector. Wiper motor should operate. Replace as required.

REAR WIPER SWITCH TEST

Note. Testing information for rear wiper switch is not available from manufacturer.

Removal & Installation (Elantra, Excel & Scoupe)

1. Remove wiper arm/blade assembly and retaining nut. Remove cowl top sealing cap by removing its plastic retainers. Remove cowl top cover. Remove wiper motor harness connector.
2. Remove wiper motor mounting bolts. Make reassembly reference mark on wiper linkage and wiper motor crank arm. Disconnect wiper linkage from motor crank arm, and remove motor. To install, reverse removal procedure. Adjust wiper arm-to-windshield trim distance. See ADJUSTMENTS.

Removal & Installation (Sonata)

1. Remove wiper arm/blade assemblies and retaining nuts. Remove cowl top cover panel screws. Remove cowl top cover by prying upward. Remove air inlet covers by pressing side tabs. Remove wiper motor harness connector.
2. Remove wiper motor mounting bolts. Make reassembly reference mark on wiper linkage and wiper motor crank arm. Disconnect wiper linkage from motor crank arm, and remove motor. To install, reverse removal procedure. Adjust wiper arm-to-windshield trim distance. See «ADJUSTMENTS»(/hyundai/elantra/i-1990-1995/remont/wiperwasher-systems/#wiperwasher-system) .
