Fan will not operate with normal controls however when jumped direct from accessory outlet it using modified plug-in adapter and male connector blades it operates fine, resistor was replaced by known good one, relay was replaced along with fuse. any ideas on what to check next and how? These steps point to the only solution being climate control module on dash or is the ECM the issue, the rear blower works fine.
Yes it does look like a Climate Control Module mode actuator problem. dismantle the climate control and check mode actuator are operating when juice is given to their terminals.
