So driving on the highway yesterday I hit a bump (Pennsylvania roads suck ass) and my music just went out. It won't turn back on. When I turn the car on, the stereo just will not power on, none of the buttons related to playing music function: power, tune, any of the radio buttons, nothing. All the A/C related buttons work fine. I tore apart the dash and checked connections, everything seems intact. Checked the related fuses, all good. I've seen many posts on this happening after jump-starting the car, but this happened after hitting a bump (not even a really bad bump, I've hit way worse). Anyone have any ideas?

 

undo the battery and have the radio codes handy! wait 20 minutes and reconnect the battery and see if it works! Also check the connections on the amplifier, it's in the passenger footwell to the right of the glovebox!

 

Same thing happened to me. I currently have my whole dash apart. Took the stereo out, checked the fuses, the wires behind it. I can't figure it out. Frustrating. I'm from Lititz, and can confirm these PA roads suck.

 

At least I'm not the only one! Let me know if you ever get it fixed! This is killing me, thinking maybe a loose ground wire? I can't seem to find a ground though...

 

Check if you have power at radio connector.


Connector A pin:
- #10 - always battery power
- #20 - always ground
- #2 - battery power when key ON or in ACC

Check with test light.

Does the security light blinks? Does radio (CD changer) makes noise when connecting plugs to it?

 

(Sorry to post on your thread OP, but perhaps we have related issues.) But right now I have power going to #10, #20, #2 is good also. I'm gonna plug in the radio for the 3rd time and see if the CD changer shows any signs of life. I do see some stupid looking aftermarket alarm in here, ne nice to know how to do away with that. I also read somewhere on here about cruise control having something to do with the audio. My cruise control never worked. But that could be totally unrelated. My whole interior is out though it's driving me nuts.

 

Hey what's funny is my cruise control hasn't worked for approximately a year! But I doubt it is related because my stereo just went out last week.

 

Thanks for the help! I bought a test light. I got the #10 pin to light up, but that's it, even with the car running. Also, the security light blinks. I didn't notice anything with the CD player. Any ideas?

 

So #2 doesn't get any power? Try connecting the test light to positive battery terminal and probing #20.

 

Nope, can't get #2 to light up, even with car on. I did get #20 to light when connected to + battery terminal.

 

A2 should get power from under dash fuse #32. Test that fuse with test light.

If A2 still doesn't have power, either track the wire, or give radio a signal from cigarette lighter (or some other ignition key source) to check if it will power up. It it will, then taking power from that source might be a good workaround.

 

Appreciate it man, I found that that wire had broken and I spliced it back together. My bluetooth module connects now, just won't play any music. My clock is also out. I bought a new one and plugged it in, still doesn't work. I tested all the wires going into the connector and none light up, so it isn't getting power. But I see no broken wire this time, any suggestions? And I'm thinking once I get the clock display working it will help with figuring out my radio.

 

So radio works now? If so then great. What a chance that wire will break somewhere.

What Bluetooth module? HFL or some aftermarket?

For clock:


Start by checking fuses... here under-dash #7 and under-dash #21 - check if they are receiving power on both ends (when key ON) with test light.
If no then backtrack to under-hood #15 and #23. If yes then check again the connector.
Check for ground. Basically standard stuff.

Oh and I suggest getting service manual from this forum. It has all the diagrams that I'm using right now. Might help you in the future.

Oh and one tip: blindly poking connectors with test light might be risky, as if you poke wire that is a communication between modules or 5V reference or something like that things might break.

 

Thanks so much for the help, I'll definitely look into that service manual. Unfortunately the radio isn't working yet, my blutoooth (BT45-HON3 by USA-SPEC) connects now, just no audio will play, and the CD/Tape deck won't work either. It seems like all the wires from the stereo and the clock converge eventually, so maybe I need to check out something back there. Appreciate all the help!
