Need help with movie title

Maybe in the wrong forum but...

Okay I rented this movie a few years ago, actually found the name of it, but now I can't remember.
It was an 80's movie which I watched religiously as a kid. Here goes

I think either Richard Pryor, or Gregory Hines was in this, or I can be completly off, but there was a black guy.
The man guy was black, and there was also another character, I think they were driving somewhere and their car broke down, so they entered this house to ask for directions/help.
Once inside the house they were trapped by some guy and his female vampires/ghosts, everytime they try to get escape they would be shocked/or lightning, or be dragged back into the house.
The black guy was a boxer, and had a boxing match at the end,
This was more of a comedy than a horror movie, I've checked imdb.com to no success, if you have any idea to what movie this is I'd be forever greatfull.

Thanks :)
