Need help with minor electrical problem, Radio and wipers Options

[MoveQik]

I was screwing around with the wiring on my radio yesterday and heard a snap crackle pop. Now my radio and my wipers don't work. Not sure why. I didn't think they were hooked up on the same fuse. Besides that, I have checked all fuses and everything appears to be good. I checked the fuse panel, none are blown. I replaced one fuse on the stereo as is blew but the other one was fine.

Everything worked before I attempted to "clean up the wiring." Now the wipers and rado are MIA. Any suggestions? Below shows where I hooked the radio into the fuse panel. Any advice is appreciated!

Do you have a voltmeter or just a testlight? With a VoM you can look for continuity from across the ground wire that connects to the radio/wiper motor and the chassis. If you get an open, then your ground is bad. You can also look for something obvious with your eyes, but you have probably done that already. If you haven't, look for a burnt or loose ground point. Since you heard the snap crackle pop, you probably shorted a power to ground and burnt something. It might be evident, you may even smell it.
Your circuits might be good, and you might have killed the stereo and the switch for the wiper motor.

Basically, I would approach the stereo first because it is easy to access. Pull it out and test the power/ground that go directly to it. If they are good (12v) try to wire it directly to the fuse panel or even the battery (known good 12v and ground) to determine if you smoked the head unit.

You can repeat this procedure with the wiper motor. Thats probably more tricky due to the location of it.

If you're still not having any luck I might be able to help you out with it tonight if you are interested.
