Yea, the hydraulic system is self-correcting/calibrating/etc. No issue there.

I put mine up and down manually from time to time and even leave it halfway up to clean the rear window or, one time, to work on the fuel level sensor in the gas tank!

I've seen the "top open" switch over the passenger's head fail a time or two. They often fall apart - you can look at them and tell they are bad!
