I have a 2003 9.3 Linear 2.0 Turbo -- my problem is I went to turn my radio on -- nothing -- noticed there was no onstar display on SID screen. Went thru all fuses -- everything looks good. I'm lost. The day before everything worked great. Any ideas??

 

well you should feel fortunate. yours worked for a day! mine has never worked and ive had it for 2wks so far, i just bought this tool so could take it out to see if any of my wiring is messed up. if not ive been seeing this thing as to if your battery or radio has been removed or drained, then the radio wont turn on due to loss of a specific code for your computer in the car that allows the radio to operate. i might take it to the dealer and see if they can fix it if the wiring is ok....you should too unless you already know what has happened.
