Q: How do you remove and replace Dimmer Switch, Hazard Warning Switch, Power Window Switch,Seat Heater Switch and Turn Signal Flasher on Saturn LS1?
A: The center trim panel contains up to five switches, including the driver's seat heater, fog lamp, hazard flasher, traction control, and passenger's seat heater switches, with all except the hazard flasher controlling optional accessories. To remove the left heated front seat and fog lamp switches, tabs on both sides of the switch housing must be released using a small screwdriver or pick, allowing the switches to be pushed out from the backside; this method also applies to the traction control and right heated front seat switches. The hazard/turn signal flasher and switch unit, located centrally in the trim panel, controls the turn signal lights and exterior lights, with an audible click indicating proper function. If the turn signal indicator flashes rapidly, it may indicate a blown bulb, while failure of both turn signals on one side could suggest a blown fuse, faulty flasher unit, or a broken switch. The fuse for the turn signal and side marker lights is found in the engine compartment fuse/relay box, and if blown, wiring should be checked for shorts before replacing it. To replace the hazard flasher and switch assembly, tabs on both sides must be released, and the assembly pushed out from the backside, ensuring the new unit matches the original. For vehicles with both traction control and heated seats, the switches are part of the same assembly and must be replaced together if defective. The instrument panel dimmer switch requires the removal of the knee bolster and the left vent/dimmer switch assembly retaining screw, followed by pulling out the assembly and disconnecting the electrical connector, with the dimmer switch removed by depressing locking tabs. Power window switches in the center console can be pried out carefully with a panel removal tool or screwdriver, followed by disconnecting the electrical connector, with installation being the reverse of removal.
