back up lights and od switch no worky

[MR BOND]

Hi, My Back up lights and overdrive switch quit on me. It’s not a fuse and all the bulbs are good. The only thing i can think of is that i did something when i had the gage cluster out to replace some of the bulbs in it. Is there something back there that could case these two things to quit.

Thanks

This is quit urgent as i have my 3-year government test coming up and it will not pass without the reverse sights.

Check your transmission....the power plug that connects those might have pulled out...the reverse light switch is inside the transmission....
