Hello, I have a 2013 town and country, the front AC blower stopped working rear blower works fine, checked voltage at front blower module (with built-in resistor) no voltage coming in at dark blue wire, checked the wire at TIPM no voltage, does anyone have the internal schematic of the TIPM, or has anyone made a bypass to get power to the blower motor, I hate to spend $500+ on a new TIPM when there must be an easy fix, thanks for any help
