Need a Spot
Hi,the heater blower fan on my 99 Sporty only works on the highest setting #4. I know that if the fuse was blown it wouln't work at all, but checked just in case and they are all ok. Is there some kind of resistor or relay that controls the speed for the fan or did the switch go bad? Thanks.

its the switch. mine did the same thing, took the switch apart to find it had melted inside and would only contact on the high setting. Bought a "new" switch from a salvage yard and it worked fine. It is NOT fun to replace though!

there has to be a resistor for the motor to spin slower speeds, so they usually put them in the air box to help keep them cool, so it may be a switch or the resistor. I don't know much about the electronics in the sportage.

Body Damage is Cool
The resistor is above the feet of passenger. I think the extra one that I sold was blue alum heat sink. Get a flash light and look below the glove box. The switch is a pain to change but not impossible. about a 2 cocktail job.

Good luck.

Need a Spot
Took the switch out and apart and it's good, it not melted(fairly simple to remove) tried to make the other speeds work bridging it with a piece of wire and still only the highest setting is the only one that works. I'm guessing that there's no way to test the resistor so will probably have to get one. Thanks for the help!

you could also check the harness to the blower motor unplug it and test to see if you get different volts at the setting if you do I would bet the blower motor windings or internal diods are bad

if you only get volts at high and no volts the the resistor of switch, if you do get a volts change the blow motor is bad

the blower motor should make a sound like a bearing going out if it was to that stage, and the reason it works on high is that its a straight connection , as in FULL voltage. the resistor is needed to reduce the voltage, therefore making the motor spin slower, and they get pretty hot in the process, so it needs to be in the path of air flow.

I know the same thing happened to me in my old ranger, and it was the resistor.

you SHOULD get voltage at the harness on all settings, its the output to the blower motor that is fed through the resistor itself. (except on max) <img src="/forums/images/graemlins/butwiggle.gif" alt="" />

test the resistor for continuity find where speed 4 is and test that then work from there.
