Electrical: How To Replace Your Reverse Light Switch MU3
#54
Photo of back-up switch location
This is the best diagram I have found. It all depends which engine model you have the 2.0L is a pain in the butt all around, the switch for it is under the fuse box. took me a half hour just to find it. The way I figure chevy had their hand in designing it so that you had to go to the dealership to get this stuff repaired but screw that!

Thanks to everyone above. This was a quick and cheap job. I have a 2.4L Manual and it was behind the drivers side wheel, and happened to be a 3/4 socket. Part cost $46 at the stealership and took me about 10 minutes. Again, thank you guys!

Also, I forgot to add. When You go to Auto Zone, they don't have that part listed for Cobalt. I told them to check and see interchange parts. It ring up showing listed Saab and I told them that it's the same as Cobalt. They didn't believe me then I put it in then I showed them. They believe me alright, they were like I am surprised that our system didn't updated. I was laughing and left. LOL!

Did this the other week and was very simple, even for an automotive newbie like myself. The hardest part is making sure you have the right extensions as it's pretty far down.
Also, it ended up fixing my cruise which also stopped working around the same time.

]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![/QUOTE]
