My reverse lights don't work, has anyone else had this problem and how did you fix it. I've checked the bulbs and there good, and the fuse is not blown. Any help would be greatly appreciated.

 

well for starters...what kind of car do u drive? on my blazer i hafta jiggle the shifter to get the reverse lights to come on...but its also 16 years old...

and....dont u have a warranty...if so why not just take it to gm and make them figure it out...

 

I got an 05 chevy cobalt coupe, manual tranny

My cars got 54000 miles on it, so no warranty anymore bumper to bumper at least.

 

have u tried jiggling the shifter knob? and mabye have someone else put the car in reverse while its running then look for yourself...cuz mabye ur tryin to find out for urself if there working by putting it in reverse while its not running....

wow shitty warranty..i got 5 year or 150 000 kms on my car

 

I've tried that with no results, i'm noy sure were the reverse sensor is located, i'm thinking maybe that it may be broken or a plug came loose, the only two sensor that i've found so far are on the bell housing and the plus were tight.

 

The back up lamp switch on your tarnny is not on the "bell housing" it's lower near (just above) the LH axle/output shaft. It has 2 wires, pink and light green. If you find the switch you can do a bsic diagnostic. Unplug it and with the IGN SW in the RUN position, "jumper" across the 2 wires and the back up lamps should turn ON. If they DO the switch has issues, if they dont - you have other "circuit" issues.

In THAT event the next check is to confirm B+ on the pink wire with a test lamp and we can go from there...

Mine did the same thing a few months after I got it. I took it to the dealer and they said that I had a bad ground...I never asked where. I know that's not too helpful, but maybe a start....

 

I did what you said with the jumper and sure enuff the lights came on. it's a bad switch, i'll order one from new gm parts. thanks for your help WOT +1 for you.

 

How do you check it?
