What fuses are required for the 2007 Chevy Cobalt

See if the brake lights work, if not check the fuses and brake light switch.

Which fuse was it? Why is it a secret?

As far as low beam, did you check the bulb?
You have left and right low beam fuses, underhood fuse block. Not only check the fuse, check the fuse circuit for voltage.

its underneath the hood right above the battery compartment.

You can find the fuse diagram for both the interior and exterior fuse boxes at https://automobilediagram.com/chevy-cobalt-2004-2010-fuse-box-diagram/ We hope this information helps!

Fuse block under the hood. Driver's side, under the brake master cylinder. Number 18. TCB#2. Replace the fuse.

There is an under-engineered ground in the reverse circuit. If you back up with the dome lights on, it could blow that fuse. There should be some extra fuses under the cover of the fuse block.

check you brake lights. if a light goes out your cruise control wont work.

the first thing you should check are your fuses. it sounds like that might be the problem

you have a bad left front wheel speed sensor. try putting a little die-electric grease in the connection

It sounds like there is something very major wrong with your ride. I think it would have something wrong with the fuse box or computer system.
