blew radio fuse

try using a scan tool to reset the cpu program in the ECM
removing a battery corrupts that program
it controls everything you mentioned including the immobilizer
as for the radio ,you will need a code to enter as it is the radio anti theft system that has operated when the battery was remove d

Like most newer cars, your Malibu has two fuse boxes. One is under the hood, just outboard from the battery. [really lousy place to put electrical stuff, right next to a container full of acid. Be sure to keep the outside of your battery clean, or you will be buying a new fuse box/wiring harness in the future] The second fuse box is located in the trunk, just above the driver's side wheel well [left rear wheel well]

The radio fuse is in the fuse compartment located on the passenger side of the console. Remove the cover on the console and then remove the fuse box cover, search out the radio fuse and inspect to see if it has blown.

Stock radios have 2 fuses that run them.

Fuse 1 is usually labeled as Radio in the fuse box.

The 2nd fuse shares circuits with other devices that are powered straight off of the battery, so look and see if your dome light works, and your cigarette lighter. If either of those aren't working, check the fuse for that item. Cigarette lighters are usually listed as Cigar in the fuse box, and dome light is usually CTSY or Courtesy.

all cars needing a boost will spark. the best advice is to hook up the dead battery first,,, the then the positive cable to your booster battery,, then the negative cable to some part of the car AWAY from the good battery.. you will know when this connection is good.

There are 2 fuse panels in car, 1 under hood and the second under drivers side of dash, above hood release area. Radio fuse should be under dash, most likely a blue(15amp) fuse. The fuse panel glossery should be on inside cover of fuse panel or in owners manual under fuses in glossery.

There is a panel on the passengers side of the car, I pulled the fuse used for OnStar because I dont use it. I didn see any labling on mine but it was the fuse located second from the top on the left side, but you have to be looking at it side ways because of the way the fuse box is orientated.
And then put it in the socket all the way to the right second from the bottom, again looking at it sideways. NOTE: My car is a 2006 Malibu LT
