Hi, I have a Volvo ec140 B LC with Miller quick hitch. The hitch has stopped working all of a sudden. When I press both switches to activate the hitch and solenoid nothing happens. No buzzer, no light flashing no activation of the solenoid. I've checked fuse and switches. No sign of damaged wires. Any help appreciated. Thanks, Eddie
Have you verified both switches are fully plugged in? With the oscillating seat frame, sometimes the left switch becomes disconnected. Then , above the battery box is a large plastic cover with 18 or 19mm screws. Remove that cover to gain access to the relay housing. Carefully remove the cover. Many times the connectors have become unsecured from the housing. Resecure everything with all the little torx screws. Now switch your horn relay with the quick attachment relay. See if that straightens thing out. Good luck
