Won't Turn On With Car On

I have a 2003 Oldsmobile Alero, the radio works just fine as long as the car isn't on. As soon as I turn it on the radio won't even turn on. I've double checked the wiring, any other ideas?

SOURCE: 90 Civic EX electrical problem. Yellow constant power wire only giving 3.5v?

The first thing I would do is check the yellow accesory wire for chafing or breaks. If it is touching ground somewhere it will loose voltage. Also check your cigarette lighter outlet. I have seen these cause shorts with radios since most (not all) Honda's have the stereo and lighter on the same circut. Also, a question for you, does anything else inside the car not work right or seem like it lacks power? Respond back quickly so I can help you more with this issue.

Pulling the postive battery lead for you car battery, for a couple minutes, and then re-securing it again might help.

SOURCE: 04 expedition radio won't turn off after I take

Does it turn off when you open the driver side door? If so, that's normal. My car also keeps the radio on when the key is taken out of the ignition until I open the driver side door. If the driver side door is not opened then the radio will only stay on for 8 or 10 minutes though. If it's not turning off ever, even when you open the door, then I don't know what's wrong with it.

2002 alero ran.shut off won't restart.Replaced fuel filter,now it gets gas,but still won't start.

For some reason aleros have this problem every once in awhile. It might be the security on the alero. What you would have to do is turn the key all the way to accel i believe right before you start it and let it sit for about 13 minutes. affter this the security will recognise itself and start your car

I have a 2001 Alero, rear defrost isn't working at all, frost inside my car, won't defrost and heat isn't working! :( HELP any idea's... I thought it was the heater core but there isn't any leakage un

You definatly have water inside the car. Pull the carpet back in the front and rear checking for water leaks. The only way frost can develope inside a vehicle is the presents of moisture.
The other possibility is your HVAC drain is plugged and water has built up inside the heater motor area. Have the drain checked and cleaned.

1999 alero light on the dash won't turn off but car strarts fine

The security light normally indicates that there is a failure in the antitheft system. If this is a new occurence, id imagine a failure will soon follow. If that light has been on since you've owned the car, somebody may have bypassed the system in a cheap way that leaves that light on. Here is a link about the system and how it works.

2003 alero steering won't lock and nothing happens when you turn the key in the ignition

If the security light keeps flashing,you might as well do a reset.
Be sure to turn off all the accesories including the radio before you start the process.
Insert the key to the ignition switch and turn the key to ON position without starting the car.
leave it ON until the flashing light (security) stops.It will take approximately 15 to 20 minutes.
As soon the flashing stop,turn the key to OFF
position and start the cart.
Hope this help.

Radio won't turn off.

The radio should still shut off after 20 minutes even if the door is not opened. If it stays on longer than this there is still a problem..
