Have a 1993.5 Toyota supra. the radio works, changes stations, problem is no sound at all other than a little bleep comes out of the speakers. the main fuse in the engine compartment is good. really hard to get at the other fuse in the driver foot well. any idea’s? blown amplifier? thanks.
TSFerguson, double check ALL your fuses using a Automotive Fuse Tester because certain vehicles may have a wire tied into another circuit not labeled as car radio. You may have additional fuse boxes by the driver side of the dash, passenger side of the dash, driver kick panel, passenger kick panel, under the steering column or under the hood. If all of your fuses are good, your 1993.5 Toyota Supra factory amplifier (if equipped) may be faulty. We suggest you take your car to an experienced audio installer and have them troubleshoot your problem. Hope this helps. Good luck with your 1993.5 Toyota Supra radio troubleshooting.
