The other day I noticed they quit ..Today I looked for a reverse fuse and can not find one..I checked the bulbs and connections and all seem fine..Anyone have an idea what it could be...Truck is in Sig...

 

Anyone , could use some ideas here if you have um..

 

I would be looking at the reverse switch located in the shifter area.

 

check all the fuses to see if any are blown, tranny switch (continuity) and check cables (corrosion and oil contamination), check bulbs,
if all else fails just use a flashlight, haha

 

my backup light stopped working the other day too. I just pulled the wiring harness on the sensor tapped into the tranny. (I have a 5spd) and jumped it with a paper clip. When I started my taco up and the brake lights came on, I knew I just had a bad sensor...

Check the Guage fuse in your driver's side panel.

 

Thanks for the replies..Ill take a look at the tranny switch..
