Need some info, schematic if possible. Have issue with electric coupler.
Serial number? We need more details. What specifically is wrong with the coupler?
All I know is it’s not working. I was hoping to know the wiring of it and get some info. It’s electric coupler. If I had schematic I’d be good. Is there a relay or fuse,or breaker? Does switch go straight to motor or hit relay first?
Fuses F7 and F14, and 3 relays - K4 (acc relay), K13 (lock relay) and K14 (unlock relay). If your lights and heater blower motor work then we can rule out the accessory relay K4 and Fuse F7. From the switch it goes to the relays K13 and 14.
