:is it worth borrowing an air control unit/piece? i've tested all the relays, they're 100%. when driving, the blower will turn on by itself, then turn off, and it's random...the a/c blower is not getting 12 volts as of this mornin and my DMM reading, so really not thinking it's a bad blower at all...checked wiring at the control unit and the blower, everything tight. :short of that, i'll just put the blower on a dedicated 12 volt switch. thanks in advance.
