First question.

Do you have a Automatic or Manual transmission?

Check for voltage at the back up light switch on the shifter. Without looking at the schematics, one wire will be battery+ with the key on, engine off. The other wire is the feed wire for the lights. Next check that the switch is ok. Check for continuity between the two wires coming off the switch. Should have continuity with the shifter in "R" only. If both check good, its time to check the lights themselves. A bad ground is quite often an issue with these older cars.
