I changed out my battery, but now my windows, a/c and radio aren't working.

have to check manual for reset codes for radio should fix

Wrong amp fuse or maybe you have a loose wire or a short somewherecausing the fuse to burn out?

Take both battery cables off and touch them together for about fifteen seconds. Put them back on the battery and try your window switch. This worked on my 2000 Grand Cherokee. This was information given to me by my mechanic when he was to busy to get me in right away.

have u test the battery and the alternator?

ground wire

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.

the radio may have a security code in it so if it is stolen it will not work you will have to either check your users hand book or talk to the dealer to find out the code in the radio & reset it, once the power is disconnected from a radio that has a security code activated it will not work until it is recoded.....hope this helps.....cheers.

when changing your battery your radio will go into lock mode you need the code to unlock it

Try unhooking the battery, turn key on, leave door open, then connect battery, start engine immediately. The battery saver module thinks it's saving your power!!

This may sound silly but place the actual key in the drivers door and cycle locked and unlock this should reset the security system.
