I have a 02 KIA Sedona, the fan switch for the front does not work. Upon taking the dash apart and trying to replace the switch I discovered the switch was burnt and melted. The wiring harness looked a little bunt and melted.
Before I spend the 900+ for the labor and whole new front dash wiring hanress. I wanted to try this, I wanted to cut the harness and try and get the clip off the old swtich. If I can get the clip off the old switch I wanted to Crimp cap and or solder the harness back back to gether.
If the wire on the clip is bad, I want to add new wire to the clip and reattach it to the main wire.
How do I test to see if the main harness is still good? Meaning after I cut the harness and expose bare wire, How can I test to make sure it has the right amount of juice? No fuses are blown or melted and everything else works. The wiring for the front fan motor and resistor both have the about right power.
Should the harness for the fan blower switch have 12V going to it? What should each wire test out at? I think it has 8-10 wires in all in differnt colors.
If all of the above fails my last plan of action is to cut the harness and solder the wires directly to the brass prongs on the new blower switch. If I can not cut the clip for the harness off the old blower switch.
Any and all help will help me. At this point I have nothing to lose, KIA doesn't sell this section of the harness. They told me I have to buy a whole new front harness. So If this fails or I mess something Up, I'll already have to replace the whole harness.
Thanks for all your help.
