I noticed my reverse lights don't work when my car is in reverse...however they do flash when i lock the car with the key fob.. Is there a fuse for the reverse sensor? Is the sensor on the shifter or in the transmission? Not sure where to start. Thanks

You can do better than that. Is it auto or manual? You don't have your profile filled out and you don't give the info in the question. They are not the same. I have a picture and instructions to change the backup light switch in the transmission if it's a manual. Let me know.

Sorry, im a new Vette owner and new to the forum. Its a 2003 Z06, so it is a manual.

It's on the transmission, passenger side. Unplug the wire and short the two pins in the plug you pull off together with a jumper or needle nose pliers. Turn on the key, if the b/u lights come on, the switch is bad (common). The switch unscrews out of the transmission, screw in a new one, reconnect the plug and you're done. You don't have to drain anything. It's harder to jack up the car than to change the switch. If you have a connection to someone with a lift, you're in business.

When my reverse lights didn't work, I replaced the reverse light switch on my tranny - If I remember correctly, it was only about $20.00

When my reverse light didnt work but they worked with fob lock it was the fuse, not the switch.

Still not checked it?

I went out today and there is no fuse i was able to find only a relay. I dont have access to a lift and and theres snow on my driveway so i went ahead and ordered the switch for 9.99 at autozone.. Hopefully that does the trick. Thanks for that diagram as well!

Same here! I'll be replacing the Tranny switch next week.

Just got my switch at Kragens <$10 ... will install next week.

Before you do any of that, check your fuse. The fob flashing fuse is on a seperate circuit from the actual reverse light fuse.

DomZ06

I couldnt find any fuses for it, only the relays and the one for the rev lights was diff then the rest so i couldnt switch 2 to check it...

I had the same problem. Checked the fuse and it was blown. Replaced fuse and put car in reverse and fuse blew again. Replaced switch and lights have worked fine since.

Many thanks to the CF guys for their tutorials.

the fuse box w/reverse lights in it is under the dash,passenger side,floor board, pull the carpet down look way up under dash, its there!

ronssito

Did that weeks ago ... fuse is OK.

Thanks.

Hey guys, I just noticed that once I switched to LED reverse lights, they turn on very dim when key is in 2nd position (right before ignition), never did this before as far as I remember with normal lights...when car goes into reverse, works fine at full brightness, but they seem to be on dimly all the time...

Have any of you encountered this?

65GGvert

I've never heard that, but from a strictly electrical standpoint, if they are only on dimly with the key on there must be a high resistance short in the b/u light switch. It supplies voltage to the lamps and they are grounded on the other side, so if they are glowing the voltage could be "leaking" through the switch. It may not be opening the contact fully when not in reverse. You can buy a b/u switch for around 10 bucks and disconnect the plug on the transmission and plug it into the new switch to see if the lamps still glow. Check for any conductive material in the plug that would cause the voltage to bypass the switch while your down there. Post what you find.

Check fuse #20, it will be marked as a park, neutral fuse, but you do not have that fuse since it is a MN6. I if the fuse blows after you replace it, the the reverse switch in the trans is bad.

DarkSpeed

hmmm...if there was a problem with the fuse, the lights wouldnt turn on at all...mine turns on dimly when car is started or in 2nd key position

I'm thinking maybe the relay could be the problem? somehow transferring a low current to dimly light up the LED's?

A couple years ago I had the same problem as you DomZ06, and 65GGVert was a great help!!

I just did a search for my old thread and after much messing around you want to check this: For the fuse box under pass kick panel, my book says fuse #21 is "Brake-Transmission Shift Interlock". This is the fuse for the reverse lights. Check it.
