2003 saturn ion sometimes the key will not come out of the ignition

SOURCE: saturn ion blower motor

lower settings as far as speeds for your blower motor go through a resister block to reduce the voltage your blower motor receives to make it turn slower. If it turns slow on high you would have to check the voltage at the blower motor, should be the same voltage that would be at the battery. There could also be material in the blower motor fan like things a mouse could have put there. Causes the fan to spin slower and also blocks the fins from pushing air. Any strange noises would be heard unless you have had the prob since you owned it and could not detect any changes. It could be even full of stuff and still
be in balance. but it could be a few other things.

SOURCE: saturn ion,sometimes wont start

The problem is in the ignition - the grease gets thick in the cold and doent turn quite right the first time. everything turns on, but the anti theft system thinks you have the wrong key so shuts off pwer to the starter. it takes 8-10 mintues to reset. That is why it normally starts when you come back later. I have had the same problem and done tons of reseach. Right now my temp solution has been a small heater and an extention cord. I keep it plugged in over night on a medium setting - just enough to keep the inside temp above freezing. I am also researching remote starts because saturn dealership charges $250 to replace the ignition, and a remote start will run about $300. Saturn wont do a recall because they feel it is not a safety hazard. I say that is bull. Good luck!

You need to replace your ignition switch. If it has already been replaced then you will prob. need a BCM.
