basically retired but work every day,
I have 35D, open station just rolled over 700hrs on the clock. its 5 or so years old.

Last week we had a big rain followed by cool overcast weather. I got on and started it up and the monitor was a little fogged up with moisture. Never had this happen before.

Everything worked fine at first, after a few minutes the travel started actin up a bit. was walking slower than normal and when you would work any function it would speed up. (opposite than normal)

Then the 3rd function stopped working and the travel started working normal.

A few days passed and before the monitor was cleared up all together the 3rd valve started working again.

Now today the 3rd function only works in one direction, I have an auger on it right now and it will dig but wort back up.

Then it started backing up but slowly,

Then it quit alltogether,

Now it works again in both directions but makes a little noise in reverse.

Any and all thoughts and input greatly welcomed!

Thanks in advance to anyone whom can help.

The auxiliary lever on that machine (right joystick) is also the computer for the auxiliary control. Other than the fuse, two solenoids and the control valve spool that is the whole system. Sounds like a moisture issue??

Where are the solenoids located and is there anything in the monitor that controls the third function?

On the bottom of the ROPS/Cab floor I believe. That requires cab tilting (see attachment). No the monitor does not have anything to do with auxiliary function (again, see attachment).
