Can you help????

I have a 95 Honda Civic HX 2-door, 5-speed. The problem is in the heater mode, the two slowest fan speeds do not work, two upper speeds work fine. Did not check air-condition mode because the weather is not warm enough outside. Fuses appear OK. Any suggestions would be great. Thanks in advance.

here is a on line manual with a schmatic of the honda civic. speed selection done by a resistor devider and a the speed select switch. dont know where the resistor is located but it may be the easy to verify. the fan motor is below the glove box. above where the passenger right foot, maybe the resistor is there too.

the selector switch has a odd logic pattern to it, guess you could start there, may have to remove the radio to access the heater controls.

high probability its the switch, the fuse is good because the hi speed selections are working, just a thought... if 2 speeds are gone maybe only a wire is loose on the switch or resistor.

 

I have no info on your specific car, but if it does use resistors as jah stated, they will be mounted inside the fan housing.

The resistors will get hot as Hades during operation so they put them in the air stream to keep them from frying. Oddly enough it's the slow speed resistors that get the hottest, so it doesn't surprise me that they would go first.
