first off i Have a base 1986 mazda Rx7. problem is i get no sound from my radio and my clock is turned off i checked all the fuses and they all seem like they are non tripped/popped so im stuck of why i dont get sound or my clock is non working. also to add my warning lights stilll work any suggestions would b nice thanks for your time hope we can figure this out thanks

 

there have been many a time when the fuse "looks OK" but is not.
the blades can lose contact at the fuse box,due to weather,moisture,just plain age..etc.
Try replacing them.
If your car has had a previous owner you may want to see(somehow) if the radio was re-installed before you bought it.

 

Make sure the Radio, Cigar and Room fuses are good. A continuity test will confirm if the fuse is good or not.

 

The radio used to work when I got it and it hasn't been replaced I was going to replace it soon but it just stopped playing sound I'll take a look at them when I get off work and get back to you

 

Thanks to both of you I replaced the room fuse that turned out to b popped and the audio fuse was worn on the feet thanks a bunch guys I really apriciate

 

Good to hear!
