Heater problem with 2004 Honda CRV

The fan on the heater of my 2004 Honda CRV has quit working. The heater is producing plenty of heat but the fan no longer works. Can just the fan be replaced or a switch?

 

Find out, first, which is at fault. Have you checked the fan fuse? That is the most likely culprit. It will blow at the first sign of switch or motor problems.

 

More info needed. Do this with engine off in a quiet area so you can hear fan, close door so so bells and chimes are not going.
Turn key to start or acc but dont start car turn speed switch thru the speeds. Do you hear anything? does it work on low?
Check fuse first If it works on one speed it is probbably the resisitor.

 

First things first as others have said check the fuse. This should be simple enough to do and easily labeled so you can identify the proper fuse to check.

If the fuse is good then it gets a little more involved. Was the blower motor running smooth and quiet before it quit? On most CRV's the motor is not well protected and leaves and debris can enter the fan cage and cause problems. Also mice love to build nests in the fan cage.

You will need to remove some trim panels under the passenger dash area to access the blower motor but it shouldn't be too difficult to do a visual inspection and check for power to the blower with a test light.

 

I would check the blower motor relay first make sure that is perfect then if that does not work check to see if your car has a heater blower Resistor if it does then check for that.. if that does not work take the blower out put direct power to it if it does work then it might be the heater blower switch..

good luck
