My car is a 2003 monte carlo, if I try to use the directional signals they make a buzzing sound and then the brake light and the air bag light comes on along with the battery light, no signal works, the hazard lights work , I replaced the hazard switch but that didnt solve it . Batter is fine and the alternator I had them checked there is no relay for the directionals its all in one . Something is strange going on I also noticed sometimes when your driving the those three lights will start coming on as well . I had put up the windows and they all went on too , sometimes just when driving it or even stopped had this car since it was brand new never had a problem till a few weeks ago

When I get in the car at times and pout key in ignition, there is absolutely nothing. The electrical system is dead. I have to disconnect the negative on the battery for about 2 minutes to get it to work again. I also experience flashing dome light, brake light on, ignition bell ringing with nothing in it, also indicators on dash panel, security, battery, door open, low fuel, change oil soon, and they will not stop showing until I disconnect the battery again and set system. I put a compete new ignition in it, both the key part and the ignition block and I still have this problem. I was told by chevrolet dealer that there is no way to bypass the security in this car because there is a chip in the starter that prevents this. When I get out of the car and press the lock on the key fob remote, the horn blows as an indicator that the car is locked, but I can walk over and open the doors every time. The lock system for the doors is not working electrically either. I am at odds as to what to do with this problem because before I spend money to fix it, I would like to know what is causing it first. All the dealers want at least $119.00 just to diagnose the problem. And, I feel that if they want my service they could give me a break and then fix my problem. That would bring e back again and again. If you can, please help me here. The chevy dealer said gm doesn't even have a fix for this issue each and every time this has happened, the vehicle was stationary and not running initially. Ingersol chevrolet says there are no recalls on the ignition system for my 2003 monte carlo ss 3800, 3.8 vehicle.
