Just did the same thing. I think its because my heater control unit is sourced from the US and mine is a UK car. The part numbers were out by the last number. Mine ended in 9. I think I need the one ending 3?? Cant remember.
Mine was just a half malfunctioning screen so put the old one back. Just the cluster not working so glad to hear yours was just a fuse and mine is likely to go back on when I switch the fuse.
Which part number did you put in? I now have a spare US part, to go back on ebay shortly.
