I thought my side door on 89 caravan got a little off track cause it wouldn't close properly. The back of door wasn't matching up with van. SO, I tried to lift and slam it, a couple times until I realized the catch on lock is stuck in closed position. I sprayed with lube and still can't get it to open. I hope I didn't make it worse by slamming, but I think I might have. Is their anyway I can get latch free again? Thanks for any and all helpful ideas.
