Tip & How-To about Chevrolet Cavalier

No heat blowing

On most vehicles when the heat stops blowing it's usualy not a fuse or a relay but the blower motor or the blower motor resistor.
Here is a good way to check if it's the blower motor. Disconect the plug going in to the blower motor, Now run two long wires from the battery one on the negitive and one to the possitive. put power to the blower motor with theese wires, negitive to one post and possitive to the other .Does'nt matter what post you hook to the blower motor will just spin the opisite way. if the blower motor spins then you can rule out the blower motor and suspect the blower motor resistor is bad. to find the blower motor resistor all you have to do is follow the wirring from the blower motor. The resistor will be at the end of the wirring for the blower. The resistor will be mounted on the heater box near the blower motor and is usually held in by two screws.

Hi , I have a 2009 Ford E250 van and all of a sudden the switch that controls the blower motor doesnt activate the blower. I have heat if the vehicle is moving , but its not blowing heat from the vent


check for a good ground for the blower motor as if you have 12 volts at the motor it indicates a problem motor or no ground wire to complete the circuit

My heater was blowing heat on 4 and 5 and now stopped blowing heat completely, does this sound like I need to replace the resistor card?


sounds like the blower resistor,check to see if you have power to the blower if so then it's the blower motor,if not could be the resistor,fuse,relay,or control switch.
