The light switch in question is located on the back of the transmission towards the battery. You can change it yourself, just make sure you understand the wiring and if you need help ask.
To change the backup light switch on a 2002 Saturn SL2, first, disconnect the negative battery cable to ensure safety. Then, locate the switch on the transmission; it’s typically near the top where the shift linkage connects. Remove the wiring harness from the switch, unscrew the switch using the appropriate tools, and replace it with the new switch. Finally, reconnect the wiring harness, reattach the negative battery cable, and test the backup lights to ensure they function properly.
On my 1999 there is a switch in the overhead console which can override the door and courtesy light switches. I often use it if one of the kids has fallen asleep in the back with the light on.
Turn the wheels all the way to the right. Look between the back of the driver side wheel and the fender. You will see the reverse light switch just above the transaxle.
Back up light switch is bad or out of adjustment. Located somewhere on the shift mechanism. The back-up light switch seems to be located on the transaxle, just below the master cylinder. I haven't figured out how to adjust it.
I was told by my parts guy that the back up light switch is the same as the reverse light switch.
the back up light switch is located in the gear shifter console
On top of the shift housing on the very top of the trans. Has 2 wires into it 7/8 wrench to remove
To wire a light switch to a light, you will need to connect the switch to the power source and the light fixture. Turn off the power, remove the cover plate, and disconnect the existing switch. Connect the wires from the switch to the corresponding wires in the wall and the light fixture. Secure the connections with wire nuts and screw the switch back into place. Turn the power back on and test the switch to ensure it is working properly.
switch is on the transmission
