This is for the intermittent radio since the starting issue can be a few things. . . .
take your kick panel down and your glove box out so you can see what you are doing and to make it a little easier on yourself.
remove the BCM that is tucked in the upper right hand corner with i think three conectors on it.
pop it open should just be a plastic box, should looks like this. That relay i have highlighted breaks the contacts on the board and causes the intermittent radio and power windows if you had it.
take the board out flip it over and find the broken solder on the leg of that relay. Should look like what i took a picture of if you can zoom in. It will be a little ashy around the solder and you will be able to see a small slit, hard to believe it would even do it but it does.
Check this out before you spend the money on anything . . . it was a free fix for me and has been working since
