This year the (I believe original equipment) power jack on my venerable Airstream seems to have quit. For some reason, it will go down, but will not raise. The type is the same as in this image (http://motorheadltd.com/Thingy.jpg
) I found online - seems like it is basically a starter motor with a three way switch and some sort of a worm gear on the top that raises or lowers the central support pipe thingie.
I am a bit at a loss as to how to fix this. Does anyone have experience with these? Could it be just the switch?
Thanks much in advance,
