Forgive me if I'm in the wrong spot but 7 kids, cold weather and no heat is an emergency to me! I'm replacing my blower motor and resistor in my 87 E-350 Club Wagon, 6.9l IDI, factory A/C with rear heat/AC. I get where the 4 wire plug goes (on the resistor) but the old connector from the Ylw/Rd wire melted and I'm not sure how it connects. It appears to connect (in the only diagram I could find) to both the blower motor AND resistor but looking for a connector on rockauto, I don't see what might be correct. Anybody have pics or an 87 van wiring diagram? My Haynes manual has plenty of diagrams but not one includes the heater/ac circuit. Thanks for any help you can offer, I do appreciate it very much!
