Trying to help a friend out with this. Stock, low mile (<100K) K1500 with dual A/C. When he shuts it off and walks away (locked up, keys with him) it will sometimes start the HVAC fan on it's own. Doesn't seem to matter what position the fan switch was left in. Also, blows on HIGH regardless of what position the fan switch was left in. If he gets in and turns the ignition to "ON" the fan will return to the setting he left it in. What he's done so far: Replaced the blower motor resistor. Going to replace the blower motor relay behind the glove box next. Any other suggestions or are we on the right track?
Thanks.
Thanks.
