Welcome!

The black plastic panel in front of the windscreen is designed to fold up from the passenger side. You need to put the wipers in the "service position" to make it easy. Turn on ignition Turn it off and operate the wipers. You get one change to move them to the vertical position while you hold the switch. You don't get the half dozen of sweeps and self park. If it dosen't work. turn the ignition off and on again.
When I said that the plastic is designed to fold up, it will be very old and may crack a bit.
Once under, you can clear the drain, and you can unclip and remove the pollen filter which will let you see the bloer and check if it rotates without snagging.
