Hey guys I have a 2003 mustang automatic v6 with 122k miles and have some questions. So I was driving on a snowy road, and I went to turn around on some ice and this happened. When I applied the brake the ABS kicked in and wouldn't stop until I got to dry pavement. When I was in the snow the car wouldn't go forward or back. The only tire that would spin would be the back right one. The back left was seized up. After my friend pushed me out the car was fine until I stopped on the road where there was ice but it wasn't so slippery to get stuck. I put it in park( ABS light on dash still on) then back to drive and the back left tire still wouldn't spin. Then I put it in reserve and it spun fine then to drive and it was fine. When I got to pavement the ABS turned off and it goes from park to drive fine and rolls. Does anyone know why this is happening and if anything is broken or malfunctioning. If it helps the brake pad wasn't hot when it wasn't spinning, and traction control was off the entire time. Any input would be helpful. Cheers
