My heater fan inside stays on even after i turn the car off and remove keys

I would check for a stuck relay first. It depends on where the motor is getting power from.

98 buick century turns over wont start

Rose, Can you hear the fuel pump 'buzz' for a few seconds when you turn the key to the 'on' position? Is so. and I know this sounds crazy, but try turning your heater fan switch all the way to the high position and then try cranking it. Another Buick Century owner told about this in another forum and it works for him and others. Apparently there is a fault in the computer and the electrical current draw from the heater fan has a positive effect on it. It's worth a try. If this works for you please post on this site so that others may benefit. Thanks

My 2000 Buick Century Custom heater/ac fan stopped working. I can feel a little heat coming through the vents so I think the heater coil and water circulation are okay. But, its cold these days, and I...

it does sound like the heater motor fuse is blown -- but if you check it and it is good ( not blown ) then it could be the heater motor itself or even the heater switch/relay. check all the wires going to the heater motor. -- try and give the motor body a little love tap,, ( this sometimes works ) and tells ya that the motor has a bad conection or the brushes are bad.

Hi, this symptom indicates restricted flow through the heater core. Recommend you try back flushing the core by removing the heater hoses from the heater core (in the engine compartment) and hooking a garden hose to the lower port using a splice. If the core will not back-flush, replace the core. Please let me know if you have any questions, and thanks for using FixYa.
