2008 chevy cobalt
 

After the battery died we jumped the car now the window lock button and the remote entry does not work also the service tire monitor message came up I have checked all fuses cannot find any that are blown is it a relay?

Welcome to the forum.:) Check the Audio System fuse 23 in the floor console fuse block? If so, you'll need to get the RCDLR module serviced. See TSB_08-03-16-001B.pdf - Windows Live.
