Avalon 2005-12 :: Rear Sun Shade Go Up But Just Won't Go Back Down

I use the rear sunshade in the summer months, but not all the time - just here and there.

There has never been a child, or anyone in the backseat who has ever messed with the rear shade, it either goes up or down, and has never been messed with.

Today I went to put the shade up, and all I heard was a click from the back area where the shade is. I tired it several times, but all I heard was a little click, and the shade did not go up.

I put the car in reverse (which causes the shade to go down when its up), I put the car in drive, then returned the car to park. I hit the button again, this time the shade came up.

Once the shade was all the way up, I waited a minute and pressed the button again. The shade arms started to fold down, then stopped. The shade will not go back down. I put the car in reverse, and it attempts to bring down the shade, but it wil not go down.

My thinking is, its not the switch (because the signal is getting to the shade mechanism, I can hear a click back there, even if it doesn't go up or down).

I'm thinking it's not the motor, because it "did" go up, it just won't go back down. Although, it could be that the motor is weak, and not enough power to lift, or lower the shade?
