All fixed now.-- thanks for the inputs from " nzenigma" and others.-- As expected the reg panel had to be removed to get to the latch but freeing the window pane required the forward of the two securing bolts to be removed completely. ( had me stumped for a while---- my bus is a 2013 model ) The latch was removed, where sure enough where on this nylon assy the cable-end holder had given way. The part damaged was small, and to quickly get a replacement doubtful. Also would likely have to buy the whole expensive nylon assy. I jury rigged a repair by using a slice of 13mm copper tube, annhealed it and opened the hole out a little for a neat fit over the damaged cylindrical nylon portion where the cable end sits, hacksawed a notch on the copper sheath, and imprisoned the cable-end ( ball ) in it. A little filing of surrounding assy to give this now enlarged part clearance for it"s part-of-arc swing and a little glue for insurance and is good to go. Happy New Year Ally Adams
