In my early 1985 model, the blower doesn't work (hasn't done since I bought it a few months ago). So I do the first obvious thing and check the fuse. Seems it had gone. Also it was an 8amp fuse and not the recommended 16amp from the haynes manual.
Then I got to thinking. My washers don't work very well. I can hear the motor when I pull the stick but it only ever gets as far as a slight dribble which makes my van just look like it's crying

So how come I can hear the washer motor as it seems something is pushing the dribble of water out yet the fuse had gone?
I replaced the fuse with a 16amp and the blower still doesn't work but I'm confused about how the washer/wipers seemed somewhat functional despite the fuse that's responsible for them and the blower not being in tact? Replacing the fuse made no improvement to the wiper/washer function. On that note, am I right in thinking I have to remove the dash to get to the washer hoses in order to clear them out?
