I was in my 79 the other day, rear window down. I went through a gravel parking lot hitting a bump. The motor is still working, so i took the glass out. But when i turn the key or push the button to roll it up or down the regulator goes only up! When its in the up position it clicks and jerks up, when its being rolled down it rolls up smooth.... Any ideas?

sounds like the gearing inside the motor. Jeff's bronco Graveyard sells a repair kit http://www.broncograveyard.com

Good luck,
