Hello,

New guy here....I made a brief post in the new members thread. I just bought a 2002 S-10 Blazer 4 door this week, and it has a weird thing with the stock cassette radio. When I turn the key to on, or start the engine, 11 rapid fire beeps come out of the speakers. The radio functions and plays music, I just have no idea what the beeping is all about. I don't ever remember hearing an S-series do that in my 22 year technician career. As I said, it's a cassette radio with TheftLock. No RDS or Bose. Tweeters in the dash pods. Right front door speaker rattles/is blown I think, and the right rear door speaker is totally inop. Is that causing the beep? Like, maybe a fault alarm? I have read online all day and cannot find any info on this issue at all. My plan was to install all new speakers and a Kenwood Excelon single DIN I've had for a bit. Between this beeping thing and the staggering amount of radio and wire harness variations I've seen, I've become kinda scared LOL! Also, the door chimes come from the dash and not through the speakers. It seems that 2002 was a strange year with changes occuring midway through. I've made a Youtube of this issue....I'll try to attach it here. Thanks in advance for anyone who can help!
