Power Seats — Acura SLX I (1995-1999)

DESCRIPTION & OPERATION

WARNING

Vehicle is equipped with Supplemental Inflatable Restraint (SIR) system. When servicing vehicle, use care to avoid accidental air bag deployment. SIR system-related components are located in various locations throughout interior and exterior of vehicle, depending on application. Do not use electrical test equipment on or near these circuits. If necessary, deactivate SIR system before servicing components. See appropriate AIR BAG RESTRAINT SYSTEMS article in RESTRAINTS.

The power seat system components consist of front/rear tilt, slide and recliner seat switches, front and rear tilt motors (driver's seat only), slide motor and recliner motor. On all models, power seat motors can be actuated by operating seat switches enabling driver or passenger to adjust seat to desired position. Seat adjustment may be achieved with ignition on or off.

SEAT HEATERS

The circuit consists of the starter switch, seat heater switch and the heat unit. The seat heater is provided in driver's and front passenger seats. When the seat heater switch is on, the seat heater built in the seat back and cushion is switched on to warm the seats. To prevent the seats from being overheated, the circuit is fitted with a thermostat.

SYMPTOM INDEX (SEAT HEATERS)

TEST A: DRIVER OR PASSENGER POWER SEAT INOPERATIVE

Check for normal operation of power seat circuit breaker (30-amp) located in passenger compartment fuse box. If circuit breaker is okay, go to next step. If circuit breaker is faulty, replace circuit breaker and retest system.
Check power seat ground circuit (Black wire) for proper connection to chassis ground. If ground circuit is okay, go to next step. If ground circuit is open or poorly connected, repair as necessary. Retest system.
Turn ignition on. Using a voltmeter, measure voltage of power feed circuit (Red wire) at appropriate seat switch. If battery voltage is present, go to next step. If battery voltage is not present, repair poor connection or open in power feed between circuit breaker and appropriate power seat switch.
Repair poor connection or open in ground circuit (Black wire) between appropriate power seat switch and chassis ground. Retest system.

TEST B: DRIVER FRONT TILT INOPERATIVE

Test tilt and slide switches. See «POWER SEAT SWITCH»(/acura/slx/i-1995-1999/remont/seats/#power-seats) under COMPONENT TESTS. If switches test okay, go to next step. If switches are faulty, repair as necessary. Retest system.
Test front tilt motor. See «POWER SEAT MOTOR»(/acura/slx/i-1995-1999/remont/seats/#power-seats__power-seat-motor) under COMPONENT TESTS. If motor tests okay, go to next step. If motor is faulty, repair as necessary. Retest system.

TEST F: SEAT HEATERS ON BOTH SIDES DO NOT HEAT UP

Check for normal operation of C-2 (15-amp) fuse located in dash fuse box. If fuse is okay, go to next step. If fuse is faulty, replace fuse and retest system.
Check power seat ground circuit (Black wire) for proper connection to chassis ground. If ground circuit is okay, go to next step. If ground circuit is open or poorly connected, repair as necessary. Retest system.
Repair poor connection or open in C-2 (15-amp) fuse and between appropriate power seat switch connector terminal No. 1 (Green/Red wire). Retest system.

TEST G: SEAT HEATER ON DRIVER OR PASSENGER SIDE DOES NOT HEAT UP

Disconnect the seat heater switch connector. Turn ignition on. Using a voltmeter, measure voltage of seat heater switch harness side connector (Green/Red wire) and ground. If battery voltage is present, go to next step. If battery voltage is not present, repair poor connection or open in power feed between circuit breaker and appropriate power seat switch.
