The power top of my 2006 NBC was working fine until Monday evening when suddenly it wouldn't raise. No sounds coming from the motor and top not moving an inch. Took it to the local dealer the next morning where it stayed nearly all day. They inform me a welding tool tip (the piece that screws on to the propane tank and directs the flame) was stuck in the top's motor causing it to stop. WTF? I don't weld! Anyway, I pay the $110 diagnostic fee and go about my merry way. Lower the top in the dealership parking lot just fine and head to work. Get back to work and the top will not raise. The motor is making sounds the sounds, but the roof is again not moving one bit. Take it back up there and they can't figure out what the problem is. It isn't throwing any codes or anything. Any ideas? I have been anxiously awaiting spring and warmer weather so I could drive with the top down and would love to have this issue fixed.
