Back up lights

Check fuse #15 in the underhood fuse block, its in there. Post back with what you find.

Next step is Disconnect the backup lamp switch connector, for manual transaxle or the park neutral position switch connector for automatic transaxle.
Turn ON the ignition, with the engine OFF.
Probe the backup lamp supply voltage circuit of the connector with a test lamp that is connected to a good ground. See if you have power here.(You might have a problem with the backup lamp switch assembly) also first remove on of the reverse light bulbs and put it in reverse and see if there is power at one or both sockets. Could even have 2 blown bulbs. Post back with what you find.

Check for twelve volts on both test points on fuse fifteen with the ignition switch in the "run" position. If you have that, check for twelve volts on the pink wire at the switch. Back-probe that wire in the connector with it plugged in, if possible, and when shifted to "reverse". If the connector is sealed and you have to unplug it to take the reading, do that with a test light, not a digital voltmeter.

Next, check for twelve volts by back-probing on the light green wire when shifted to "reverse". If you have it there, there's a break in that wire between that point and the splice where the wire splits into two circuits.

The number one connector in the diagram plug's into the back up light switch.

Yes it's behind the drivers side tire area turn the key to the run postion with the engine not running unplug the back up switch jump the connector that goes to back up switch across the two terminals. The back up lights should come on if they do but don't with the connector plugged in and the car in reverse then you have a bad back up light switch.I have seen a lot of back up light switches on those.

Yes it would be the same place.

Did you check the backup lamp fuse, check for voltage, goes hot when you turn the key on. Also, check backup lamp switch, on transaxle, left side of engine compartment.
