Help...door won't open all the way

Does it make any noise? Sounds like you have a hinge problem. It's rare that the hinge breaks in this manner, but I have seen it, and this is what it causes; unlike the usual hinge problems that just make the door loose. Are you positive it's hitting the fender, not something that got inside somehow? I've seen this too, but you have to take off the fender to find it...PIA... good luck!

Check and see if the fender is loose and got pushed back somehow, grab it with the hood up and try to move it back and forth. I have seen alot of people leave hardware out and daily driving vibrates the bolts loose. If not, the definitely check out the hinge thing 351 mentioned. Don't really think it could be anything else.
