WIPER/WASHER SYSTEM - EARLY PRODUCTION Article Text 1995 Isuzu Rodeo For 1 Copyright © 1998 Mitchell Repair Information Company, LLC Thursday, April 07, 2011 09:37PM ARTICLE BEGINNING 1995 ACCESSORIES & EQUIPMENT Isuzu - Wiper/Washer Systems Rodeo - Early Production EARLY/LATE PRODUCTION IDENTIFICATION Early 1995 models are not equipped with Supplemental Restraint System (SRS) and have "G" or "Y" in fifth position of VIN number. Late 1995 models are equipped with SRS and have "K" or "M" in fifth position of VIN number. Approximate date of production change is May of 1995. DESCRIPTION Vehicles are equipped with either a standard 2-speed, or intermittent wiper/washer system. Rodeo may have a rear window wiper/washer system. OPERATION With ignition on, voltage is supplied from fuse labeled WIPER to front wiper and washer switches, front wiper motor and front washer motor. The WIPER fuse is located in fuse block on left side of dash. When front wiper switch is turned on (LO or HI position), battery voltage is supplied to windshield wiper motor to operate wipers. When MIST or INT switch is turned on, operation of wipers is controlled by intermittent relay. The windshield washer motor operates when washer switch is depressed. The rear wiper has intermittent and rise-up function and is controlled by rear wiper controller. When rear hatch is open, rear wiper will not operate. Hatch gate opener actuator will not operate while rear wiper is in operation. ADJUSTMENTS FRONT WIPER ARM ADJUSTMENT Ensure wiper switch is in OFF position and wiper arm is in auto stop position. Wiper arm must be positioned so distance between vent cowl cover rubber seal and edge of wiper blade is as specified. See FRONT WIPER ARM ADJUSTMENT table. See Fig. 1. Tighten wiper arm nuts to 11 ft. lbs. (15 N.m). FRONT WIPER ARM ADJUSTMENT TABLE Adjustment Point In. (mm)

REAR WIPER ARM ADJUSTMENT Ensure wiper motor is in auto stop position before adjusting wiper arm assembly. Tighten wiper arm nut to 12-17 ft. lbs. (16.3-23.0 N.m). No further adjustment is available from manufacturer. TESTING FRONT WIPER MOTOR TEST 1) To check low speed operation, connect positive battery terminal to terminal No. 2 and negative battery terminal to terminal No. 3 of wiper motor connector. See Fig. 2. Wiper motor should operate at low speed. 2) To check high speed operation, connect positive battery terminal to terminal No. 1 and negative battery terminal to terminal No. 3 of wiper motor connector. Wiper motor should operate at high speed. 3) To check auto stop operation, operate wiper motor at low speed. See step 1). Disconnect positive battery terminal from terminal No. 2. Connect battery positive terminal to wiper motor terminal No. 6. Connect a jumper wire between terminals No. 2 and 5. Wiper motor should operate at low speed, then stop at auto stop position.

WIPER/WASHER SYSTEM - EARLY PRODUCTION Article Text (p. 3 Disconnect wiper switch connector. Using ohmmeter, check continuity between specified terminals. See Fig. 3. Replace switch if continuity does not exist between specified terminals. Fig. 3: Checking Front Wiper Switch Courtesy of Isuzu Motor Co. INTERMITTENT RELAY TEST Intermittent relay is located in fuse/relay box in engine compartment, on passenger side. Disconnect intermittent relay connector. Apply battery voltage (positive) to relay terminals No. 3 and 6. See Fig. 2. Connect ground to relay terminal No. 1. Using a voltmeter, ensure battery voltage is present (intermittent) at relay terminal No. 2. If battery voltage is not present, replace relay.

REMOVAL & INSTALLATION FRONT WIPER MOTOR Removal 1) Disconnect electrical connector from wiper motor. Remove wiper motor retaining screws. Disconnect wiper motor from wiper linkage at ball joint, and remove wiper motor. 2) If linkage assembly is to be removed, remove cap from wiper arm. Remove wiper arm nut and wiper arm. Remove vent cowl cover. Remove wiper linkage through access hole. Installation 1) To install, reverse removal procedure. If crank arm was removed from wiper motor, ensure wiper motor is in park position before installing crank arm on wiper motor. 2) Tighten wiper motor crank arm nut to 11 ft. lbs. (15 N.m). When installing wiper arms, ensure wiper arms are properly positioned. See FRONT WIPER ARM ADJUSTMENT under ADJUSTMENTS. Tighten wiper arm nuts to 11 ft. lbs. (15 N.m). REAR WIPER MOTOR Removal & Installation Disconnect negative battery terminal. Drop tailgate down. Remove inner access panel from tailgate. Loosen wiper motor mounting bolts. Disconnect wiper linkages and electrical connectors. Remove wiper motor. To install, reverse removal procedure. REAR WIPER SWITCH Removal & Installation Disconnect negative battery terminal.
