ok so do you remember when you wired your radio? there were 2 power wires. the red 12v which turns the radio on, and then there was that yellow memory wire that lets the cd pop out and keeps the time. that red wire is fused by a 10 amp red bus fuse located in the kick panel on the drivers side where your left foot would sit. also, your blower motor is probably blown it will need to be replaced. it is sitting right under the glove box and is held on by 3 10mm nuts.

 

yeah i replaced the fuse that the fuse diagram said was the one for the radio yesterday and it still did nothing. the fuse in the radio itself is good too. also i didnt wire up the radio...best buy did for the guy who had the car before me. though i did connect the remote wire to the amp but everything was fused and wired propperly so i dont know what went wrong where.
