Sounds like your GV is haunted.

But seriously, the dead audio is probably due to either a bad internal fuse in the amplifier or a bad speaker connection on the plug at the back of the radio. Perhaps a bad ground, but not likely, they are usually intermittent.

The other issues with the locks, and Air Bag light could be due to a weak battery. The Body Control Module (BCM) is very susceptible to voltage fluctuations and intermittent low voltage. If your battery is on its last legs it can produce all kinds of electronic gremlins that come and go and are almost impossible to diagnose. Have the battery load tested. I don't know if it has gotten colder recently in LI, but that will put an extra strain on the battery and these kind of things can appear.

 

annfan,
Thanks for sharing this. I wouldn't suspect battery, it starts engine without any hesitation, but I will test it anyway.
I already checked back connection of the radio and it was fine. Do you know how hard is to get to internal fuse of radio?
Thanks

 

our stock audio does no have the fuse at the back..

 

Sorry, I have never opened up my radio, so I don't know how to access the fuse. I'm assuming there would be a separate internal fuse for the amplifier. Removing the radio and then its external metal case and having a look is probably the only way to find it. A car stereo repair shop familiar with Clarion products could possible advise what to do.

It may not be just the fuse, a failure somewhere in the amp could also be the issue, in which case it may not be economic to repair. Also, if one of the speaker wires has grounded it could also cause the amp to shut down to protect itself, although that is what the internal fuse is there for. If the fuse has blown, remember it blew for a reason. If there is a short somewhere, its still there, so the new fuse may blow again.

I fear you may need professional help to fix this.

 

timeonli, I believe the radio is a Clarion PS-3037D-A (there should be a part number on the back). You can download the schematics of most Clarion radios here:

You should be able to find the internal fuse by searching through the PDF.

 

Just update, maybe useful for others.
Keyless entry problem was caused by stupid thing. I found my spare remote under passanger seat, that is why I couldn't lock the car. Unlock function worked. Second AirBag light went off , after I cleaned up all connectors under driver seat. Last problem with radio is still unsolved. I put it apart, but there is no fuse in it at all.

 

Sounds like good progress anyway. When we're travelling, my wife often leaves her remote in the GV (since women don't seem to believe in pockets). Then I can't lock it.

 

Radio Blown Twice

The radio/CD that came with my 2006 Grand Vitara all of a sudden would power on, but no sound came out. The dealership replaced the stereo and that blew, and they finally found some damaged wires. But after that was fixed, a couple of weeks later, I turn on the radio and encounter the same problem. The dealer has had it for three days and says he's done every diag on it and hasn't found the problem. He says he may have to start replacing harnesses and/or components. Anyone have any ideas? Also, I have an extended waranty that should cover any electrical/mechanical that's not due to wear and tear, yet after the last repair, they said the waranty only covered a certain amount of hours. Can anyone help me. Do I have an incompetant mechanic? I have to use them because of the waranty.

 

SKL76, In my case I found out the problem was in pillar connector. After I celeaned it up everything got to normal. See attached picture.
Hope it helps.

 

I once have a problem with my alarm system. It went off at weird moments.
later they discovered, that someone lost its cell phone (a mecanic?) and it was stuck underneat the drivers seat. when someone calls my alarm went off.

 

Good story!

 

yeah, the part may be under warranty, but the mechanics can only claim a certain amt of time for each repair. If they go over it is just like anyone else working for free. At a busy garage they cannot afford to do that while other jobs back up.
