When it snows or rains. Have replaced windshield and ruled out leak coming from firewall and hood release

change the tcm. code u0073.After no code present. but same problem is there.

I have electric seats on my Mazda 6 and sometimes when I am backing up, I have had the seat-belt hangup on the seat controls!! This would cause the seat to move back and the seat to tilt back-words, this lifted my feet off the gas or brake peddle! When this happen to me I was backing up.
I had my foot lifted up of the brake peddle and I almost drove into the car behind me! I was lucky, I was able to slid down somewhat so I could reach the brake in time to stop!!

If this has happen to you let me know Please!!!!
