I have an intermittent problem with the blower fan in my 1978 Piper Warrior. The fan works fine on the low speed setting but high speed is intermittent when some of the wires to fan connector are jiggled. My IA cleaned the connectors before and it worked for a while but is broken again. I want to have my IA replace the connector but the connector part is not listed in my parts manual. Is this a Molex connector? Anyone know the manufacturer's part number? Pin size?
