Heater Control not working on dash
OK, I've diagnosed to the full extend of my knowledge (which is not much) on fixing my heater/ac blower motor on my dash from working only on high. I've replaced the resistor and the relay still only works on high. I've checked wires and fuses, I've checked all grounds, I've followed wires, I've checked power to everything and nothing. I've also noticed that my controls won't change from defrost to vent to floor just stays on defrost. I'm also wondering why this unit turns on even when the key to the ignition is off and even when the unit is turned off the fan will still run if turned on high. I am majorly confused on this, I don't know what else to look for? Only thing I can think of is changing out the entire heater control panel. Any ideas from anyone else? This is really bugging me.. Thanks for any help out there..
