Rear ac on 1999 ford e350 1 ton van rear ac need diagram for repair or help with question.?
The rear ac quit blowing air to upper vent and only blows heat to floor vent. the ac works normally in the front of the van. we have accessed the blower but need instruction on what may have malfunctioned to cause the ac blower to stop working.
Answer
Eautorepair.net for online access to factory service manual for a fee----if the blower works, it sounds like bad a/c blend actuator door in the rear unit. if the blower does not work, check the wire circuit--bad switch, motor, ground, resistor or wiring.
