If it were a CJ or a YJ, I'd say don't worry. But I've heard too many stories of TJ's having water problems to tell you that. Mainly it's the dash. I've heard of funny things happening, like wipers coming on on their own. Things like that. I just say dry it as best you can, check everything out and make sure it's not going to blow, then start her up and drive her. She'll let ya know what's wrong real quick. Well...hopefully
