I have a 2003 Alero, and the radio won't turn off after the key is out of the ignition. I have to turn it off, but clock light stays on, and battery died. I was wondering if there is a constant power drain. I have had it looked at by a mechanic who thought it was a faulty sensor in the door. He could not find the problem. This wasn't a problem when I bought the vehicle, but has happened 3 times now. I have bought a new battery, but with - 30 C temps, am wondering if this could be a factory defect or recall. I don't feel like buying a new battery every couple of months!!! Going crazy in Canada!!!

Check wiring and see if power source is to wrong lead, usually the constant power wire would be wired to the clock or auto antenna. The poer source for turning the radio on should be wired to the power source that is tied to the ignition, so when you turn your key off the power will be off as well.
If you had said the radio did not work, I would say it was the key switch or a large fuse or fuseable link. But the radio is powered thru the key switch. The problem could still be the key switch or a major fuse, I would check all of the fuses then power at the key switch. Also check the ground connections.
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.
If you mean the radio doesnt retain the memory presets and clock when you shut the car off or turn the key to the 0 position
that could mean that the yellow wire was not connected to the red or hot/positive lead when the radio wiring harness was connect
if this worked before and now it does check the main fuse box also some radios have a inline fuse connected on the radio wiring harness (behind radio so you'll have to remove it to check, same thing with checking that the yellow wier is connected)
not sure what you mean by "electrical problem headlights" some cars shut off the electrical current to the head lights (only power to running/park lights) when the ignition is shut off or the key is at position 0
My GMC Dealer said that the problem is caused by a short in the ignition/electrical system. (seems to be a problem for many). He also said that the ABS will NOT actually work while the light is on! All my dash warning lights, radio/clock, and sometimes even ignition(turning key) have problems. The car is drivable but not working correctly. Short term solution: turn key ON, wait 10-15 min, turn off for a few minutes to 'reset' and then try to turn car on. Worked for me yesterday. Good Luck!
does the car crank or not?? if it cranks and doesnt start it could be a couple things. could be fuel pump is bad or could be an ignition problem and ur not gettin spark in ur sparkplugs. if nothing happens when u turn ur key its more than likely that ur starter is bad. if this doesnt help im sorry but this is the only thing i can think of.
Ignition switches on Aleros are notorious for going bad and causing the exact problem you describe. The next time it happens, try turning the ignition key back and forth slightly. If everything starts working again, then have the ignition switch replaced.
