The telescoping rod needs to be replaced. I hooked the drive assembly up to make sure it worked and it didn't. I checked for power and I do get constant 12v. I'm trying to figure out how the unit gets switched on. To me it looks like I should get a switched 12v from the antenna switch to different pins depending if I want up or down. So if u can supply anz answer or wiring diagram. Thanks
