Check a wiring diagram, they probably are different circuits but may share a common ground (ground is term used when connected to negative battery terminal).
Only the blower motor not working.
You have to take out the heater vents to be able to move the console forward.
Remove the wiring harness from the back of your 2005 Chevy Cavalier heater blower motor. Remove the heater blower motor retaining bolts. Remove the heater blower fan.
Jump start car and do not run heater with engine not running.
Test the resistor bank before getting into anything else. These are the speeed controls for the blower motor.
Change the fuse in the box next to the glove compartment.
Heater blower resistor is what controls the low medium high speeds...
The blower may simply have burned out. If the blower is out then the heater probably still works.
Remove the wiring harness to the heater blower fan. Remove the retaining bolts. Remove the fan from the blower. Reverse the process to install the new heater blower fan.
where is the heater blower resistor in a 2003 Honda element
not 100% sure that this is the same as 96 model but found out on mine there isn't such a convectional definition. basically pluged a ceramic heater 200w into my cigarette lighter which worked for few seconds and then stopped. checked all the fusses and all of them were ok. managed to pull out the cigarette lighter with the plug and checked the connector. with the ignition on tested the connector and noticede there was power at the connector but on the body of the plug there was a transistor that would have acted as the fuse and looked that it hade taken the strain!I am going to take it to a electronical shop to have it replaced. i belive the cigarette lighter not to be used for accesories that require "fuses" more than 15A. heater i used needed 17A or higher!.Answernot 100% sure that this is the same as 96 model but found out on mine there isn't such a convectional definition. basically pluged a ceramic heater 200w into my cigarette lighter which worked for few seconds and then stopped. checked all the fusses and all of them were ok. managed to pull out the cigarette lighter with the plug and checked the connector. with the ignition on tested the connector and noticede there was power at the connector but on the body of the plug there was a transistor that would have acted as the fuse and looked that it hade taken the strain!I am going to take it to a electronical shop to have it replaced. i belive the cigarette lighter not to be used for accesories that require "fuses" more than 15A. heater i used needed 17A or higher!.
The heater blower resister is under the dash on the passenger side. It is inserted into the side of the blower motor case.
