hi there, i had the same problem with my alhambra wipers.... first spray some lube(wd40 or similar)onto the spline shafts, where the wipers are bolted on, then as you put the wipers on slow, gently manually assist them to do the wiper motion that they would normally do if they were working. mine came unstuck this way. hope this helps.
