How difficult are these to rebuild?o No: Mine has a broken extend/retract cable. When I hit the switch, the motor just spins but I still have to pull/push the mast up/down manually. I think this is the replacement part that I need. http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=1872188602
Usually its not the aerial part that goes, its usually the worm gear inside that tends to go bad. Believe it or not, its very easy to update with a newer style one...just splice the wire in and use the old hardware and thats it. GM ones goes for like 50 to 60 bucks new....hope this helps :TU: Larry :TU:
