B2C2 -
I had the very same problem on my 69 D model a year ago: intermittent operation for a period of time and then stuck closed and wouldn't open at all. Before you dump a bundle on a motor overhaul/replacement, have your mech thoroughly check out the wiring continuity to the motor, especially in the rear engine compartment. There's a lot of heat and shaking back there that eventually causes problems.
We found an intermittent contact that finally gave up the ghost and now the cowl flaps work fine...(until next time anyway...). Also look for any hoses, cables, etc. that may be interfering with the actuator mechanism and putting extra loads on the motor. I have a Wolf oil filter adaptor back there and the feed lines occasionally work there way against the left side cowl actuator rod.
Good luck -
