I have a 29 series plow # 9029100314 with remote operation. When it works it works great, but sometimes won't do anything, which is right now. I've replaced batteries in remote, checked ground connections, fuses and power to motor. All look OK. It's like it has a mind of it's own! I have a gut feeling it's the reciever, because when it works all 4 operations work off the remote. Anyone have suggestions would be greatly appreciated. Thanks!!
