Hello
First off just to let you know I have done my research on here and elsewhere.
My direction control only goes to the windscreen (default) setting. I have had the controls out and have tried an new control switch which didn't make a difference. I have cleaned out the T junction, no difference.
I have manually moved the lever on top of the vacuum unit and it does change the direction, but when I remove the pressure it goes back to default.
Is there a good way to test the tubing for leaks? or could the Vacuum unit be faulty? I can pick up another unit cheaply, so may do this just in case. Any help would be great.
P.S the fan speed control was also only working on high, but after some fiddling with all the vacuum hoses it seems to have started working again, is this related to the direction problem?
