Welcome to the forum Iowahawki.
Although we don't have the 'remote', some of the members here have previously discussed situations similar to yours.
IF I remember correctly, there are some circumstances in which the remote system over-rides the manual switches, and
I 'think' one of things was a problem with the battery in the remote - may need to be replaced. Also, if your remote has
an on/off mode, the remote may need to be 'off' in order for the manual switches to work correctly.
The forum is pretty quiet today, but in the meantime you might also try doing a forum search using the words:
"remote" OR "rear stabilizers" (without quotations).
Hope this helps!
