Just had my oil changed, which may not have anything to do with my problem but now my blower is not working for my a/c, heater, defrost. it seems like my fan is not engaging when the engine is getting hot.

9 out of 10 times its the heater fan resistor doing this. it has wires that corresponed to diffreent speed settings for heater fan. the resistor is beside the blower motor, Your Kia Sportage Blower Motor Resistor controls the heating equipment in the
vehicle by opening and closing the fan motor. The Kia Sportage Blower Motor
Resistor allows the heating and climate control system to control the speed of
the vehicle's cooling fan. its under the passenger side glove box. undo 2 screws and disconnect the electrical connector. thats it!!
CHECK SEE IF HEATER BLOWER MOTOR WORKING, REMOVE HEATER BLOWER MOTOR HOT WIRE HEATER BLOWER MOTOR SEE IF BLOWER MOTOR WORKING BLOWER MOTOR FAULTY OR YOU HAVE FAULTY WIRING AT BLOWER MOTOR AND RESISTOR.
Hello, The power module controls the blower motor. It is located on top of the heater case under the hood towaeds the passenger side. When replacing the power module make sure the seperate ground wire is tight and that it is a good ground.
check fuse and switch for heater if good check power to blower motor at heater core if power remove blower motor and check housing for debris (leaves etc)and blower motor for proper turning unit may need to be lubed if hard to turn or seized if seized and oil/lube not working replace blower
you need to test for power at the heater motor when it doesn't work there is a heater resitor that aslo needs to be tested if you have power to blower motor and it is still not working the motor is bad. if no power go to resistor it is located in the heater box behind right side valve cover. test for power at the plug it will move from pin to pin depending on the heater speed setting if you have no power at the resistor then suspect a faulty heater module. if you need anything else let me know.
When a fuse blows, it shows a problem in that circut, generally a voltage spike, sometimes a poor ground that causes excessive resistance in the wiring, or a short. I don't know of any connection between the fuse you changed and heater, but anything is possible...Check your body ground, dash ground, heater relay and blower motor. (Motor is mounted on the engine side of the firewall on the passenger side. relay is either on the firewall or inside the power distribution center (black box near battery).
