Top fuses are10 amp, numbers 32 for the Audio system, ECC, convertible top, trunk lid cutoff, instrument lighting and 35 for the Accessories, convertible top, drivers vanity mirror light, courtesy lighting, auto-dim mirror function(option) in the auxiliary fuse box. If one of the items operated through these fuses, you will know which fuse it is. Remove the fuse and see if the arched link inside is broken or the inside of the fuse is blackened. Replace it only with an other 10 amp fuse. If it blows when you attempt to retract the top, study the linkage while extending the top, look for uneven movement left to right, indicating a bad pivot joint or interference. There is the remote possibility it may be worn or sticky brushes in the motor.
