There are a few of you that do not have any backup lights when putting your car in reverse. I hope this Helps! This is for the MU3 transmission and not the Getrag.

1. Go to your local dealership and buy GM part no. 24459626
2. You will need the following tools: 1/2 ratchet, long 1/2 extension, 22mm deep socket.
3. Shift your car into 4th gear. (please make sure the car is not running!!!)
4. Look down between your fuse box and your motor, you will see a plug with two wires on it. It will be right on top of the transmission. You might have to move some cables out of the way. However you will not have to remove or dissasemble anything!!!
5. Pull the plug off the old switch, then use the socket to remove it.
6. To install the new switch, do this backwards.

This only took me 10 minutes!

 

how much did the switch cost you from the dealership?

 

I think it was around $20.00

 

How does this happen? Like.. not havin reverse lights???
Aside from Bulbs messin up.. or folk blackenin the **** out of em..

 

from what i heard this is a common failing part

 

I replaced mine on monday it took like 15 min. very easy unless you got big hands

 

your reverse lights will not turn on when the switch goes out lol. dealer had to replace mine

 

Yeah my dealer wanted $275 to replace the damn thing. 100 of it was the diagnostics, then the 23 dollar part, then the rest labor, i was like you have got to be ******* kidding me

 

Awesome write up! Definitely a job for me in spring

 

WOW $100. Considering how long it actually takes to replace it.

 

It would be much appreciated if you could at least get a pic of the location.

 

^^true, this, I'd like to know... When does it usually go out???

 

I just ordered the part today, gonna attempt to put it on sometime soon, so megaman if you could snap a quick pic it would be most appreciated!!!

mine went out a few weeks ago, i have an 07 with around 55k

 

I'll try. It's kinda hard to take a pic of where it is located. Give me a day or two.

 

Well, let me tell you that wasnt the most fun thing to do in 30 degree weather. But, atleast I have reverse lights now. It's really not that hard to find if you know where to look. Like megaman said, look directly down between your engine and fuse box, it straight down. You will definitely need a long extension, i just used the big ass one i use to change the oil filter.

 

i like not having reverse lights! not
thanks alot man for posting this big help

 

Not just for cobalts,
but EVERY Vehical I've EVER owned, has had this switch fail.

 

can someone post a pic of where its exactly at cuz mine needs replaced

 

Its pretty hard to get a picture of it, i can try tomorrow if i have time

 

It is really hard to take a photo of the switch. I already tried to take a photo, but failed at it. You just don't have room for light. But like i said before, it is not hard to find. as long as you follow my instructions in the first post.

 

^ this

 

Just picked up an '06 ss/sc and the first night I had it I realized the reverse lights were out.. will order this part soon. Can someone post a picture of the actual switch and where its located.. I don't do well with descriptions.

 

Instructions is pretty much all you are going get. It is very hard to take of a photo of this replacement.

 

Curious, why 4th gear?

 

i had to replace mine two months ago, easy 10 min job
