67 GTO backup lights

Recommended Posts

My backup lights are not working on my 67 GTO coupe. I have a three speed trans. Checked simple things like light bulbs and they were operational and also the fuse. Checked the back up light switch and I believe it was defective based on my continuity test conducted on the trans and  on my bench. Replaced switch and still no backup lights. When I replaced the switch I put in the same spot as the defective switch. Should I try adjusting it on the trans by rotating it or look in another area.

I do not get 12 volts to the backup bulbs when the trans is in reverse. Did check back up bulbs by removing them and using battery. Also tested then installed to rule out a ground issue, all was good. Thoughts on the matter will be greatly appreciated..

Thanks, Frank

It's very rare, but you could order a column shift in the GTO.  That you??? LOL   Most were floor shift.  I believe there is a switch on the shifter (under the cover)  My his/hers has it.  When hooked up to the wiring, can you manually operate the switch?  Would answer your adjusting the switch on the trans question.

Thanks for your thoughts on the issue. My car is floor shift 3 speed. I will loosen mounting points on switch and adjust it it forward and backward to see if I find the sweet spot . Should work with adjustment. Will follow up in a few days.
