Scion not going foward

[1FasImp]

I installed 2x2 stackec FETs on my Scion TC, it worked great. But after having a head on collision with the lawn mower wheel, it stopped moving foward. I took the board off to get a better look at it. I didnt see anything ( even comparing with another board). So decided to put it all back together. After I did, I found out that the peice where the crystal goes is loose. When I pushed down on it the wheels would go foward, and when I let off of it they would stop ( I tried this many times). I was going to fix it today, by appling pressure to it and heat up the solder. But I tested it again today ( just to make sure thats what is causing the problem) and got nothing.

Can anyone help with the troubleshooting?

Thanks
