Everything was great until this morning. Car started great, but the first thing I noticed was that my radio started to act funny, then cut out & popped back on a couple of times before finally stopping. Tried turning on headlights, nothing. Also no brake lights. The a/c works great, and the windshield wipers and turn signals work, both inside and out. Checked fuses, and none appear to be burned out. Any suggestions would be GREATLY appreciated!! Thank you!!
