On my 2 Newells and Foretravel when the ignition was on the blinds would only come down a set amount to keep from blocking your view. If I wanted them down further I had to stop the engine then move them down further.
Not sure why yours aren't working now Simon.
But it's not fun until they drop down when you're driving through construction on I-20. Happened to me once after leaving Magown's place.
