hello there... my retired neighbors reverse lights arent working, trying to help him out. Dont think it's the bulbs & i'm pretty sure a fuse wouldnt control just the reverse lights. Advance auto(ugh)said it was a reverse module in the console(automatic on the floor)but i was thinking more a back up light switch....any ideas...?

THIS HAPPENS WHEN EITHER ONE OF THESE CONDITIONS ARE PRESENT: BLOWN FUSE, BAD GROUND, BROKEN BULB, INCORRECT BULBS, SHORT CIRCUIT/BROKEN WIRE OR BROKEN OR MELTED SOCKET.
CHECK FUSE BOX FOR A BLOWN FUSE AND REPLACE IF NECESSARY....
BLACK WIRE COMING FROM SOCKET OF LIGHT AND CHECK FOR CUTS, RUSTED CONNECTION WHERE LUG IS SECURED TO A METAL PART OF VEHICLE....
BULB IS BROKEN OR IT MAY NOT BE THE CORRECT BULB, SO COMPARE BULB #'S TO MFG'S SPECS, REPLACE IF NECESSARY....
BROKEN POSITIVE OR HOT WIRE THAT IS ANY COLOR BUT BLACK OR GREEN (MAY BE BLACK WITH A DIFFERENT COLORED STRIPE....
IF NONE OF THE ABOVE STEPS WORK TO SOLVE PROBLEM THAT HAVE SOMEONE GET IN VEHICLE, START IT UP, ENGAGE E-BRAKE, THEN SHIFT INTO REVERSE WHILE HOLDING REGULAR BREAK DOWN TO FLOOR AS A SECONDARY PRECAUTIONARY MEASURE; YOU WILL NEED TO CHECK THE VOLTAGE AT THE SOCKET AND COMPARE THE READING TO THE VOLTAGE RATING PRINTED ON THE BULB.
IF NONE OF THIS FIXES THE REVERSE LIGHTS THEN YOU NEED AN ELECTRICAL SCHEMATIC OF VEHICLE SO YOU CAN FINDOUT IF WIRE ORIGINATES IN THE PROPER FUSE BLOCK (SOMETIMES DURING OTHER TROUBLESHOOTING OR REPAIRS A WIRE IN RELOCATED ACCIDENTIALLY).

With the key on (doesnt have to be running - just in the 'run' not acc. position)have someone watch the lights while wiggling the shifter back and forth to see if the lights flicker at all. It may just be an adjustment , or at least if you do see flickering , you can rule out certain wiring and bulb issues.
