Hi All- I recently bought an 85 Jimmy and I added an FM modulated CD changer in my console. The radio kept blowing fuses everytime I shifted into overdrive (even before I added the CD changer). I couldn't figure out why, so I wired the radio/CD changer into accessory slots on the fuse box and added in line fuses. The stereo works fine, and it doesn't blow fuses anymore. Everytime I turn on the AC while the CD changer is on, there is a high pitched whine. Any suggestions? Thanks!
