Power top motor drowned by the roof drains All years

Check: Run the power top up and down several times. A slow or stalling roof points to a tired motor. Ask whether the motor has been moved into the trunk, and clear the roof drains.

Eight owners in four threads on a British owners' forum say the power top's motor sits where water from blocked roof drains collects and fails; several had theirs moved into the trunk, which they call the fix. An Edmunds owner review says the same, and Euro Premium Parts lists motor failures on high-mileage roadsters. One forum owner says a US car may have had a manual top as standard.
