Is there a trick to getting the knobs to lock down the soft top? One of the power motors works (passenger), but the other side (driver) will not lock down with power motor. I tried to lock this side down with the manual knob, but no luck. Am I overlooking something? Thanks

What year are we talking about? My 88 has only one pull down motor for the top. There are levers on the right that release the top and and the cover for the convertible plus a hidden switch that recycles the pull down motor. Don't know if this helps or not...
