The heater blower stopped working. First thing i checked is the fuses and they are O.K. I need something else to check before i start taking the blower apart. Any ideas it has been under 32* out for a month and i'm sick of driving around and seeing my breath. Thanks.

Check the blower motor and relay. Mine went out not too long go and had to pick one up from Advanced Auto for $30.
Put the key in the ignition and turn it so that all of your accessories are on i.e. radio, dash etc, but dont start the car.
Open the hood, and stand near the blower motor assembly and have someone turn the air controls from on and off. You need to listen to a clicking noise to see if the relay is working.
If the relay passes, then it is almost certainly the motor that is not working, since the working relay indicates power is being applied to the motor. You can bypass the relay and hook the power directly to the motor to see if it works if you want, or pull the motor and apply power to it. Also, you can use a Voltmeter on the connections to see if power is being applied.

Is the relay the little box thats next to the blower motor?
O.K. i will check it in the morning, its dark and cold outside.
