Would a blown fuse cause an electric window drivers side to stop working and cause turn signals to work sporadically?

A blown fuse will cause an electric window to stop working. It will not cause turn signals to work sporadically, they will either work or they won't. Also, I am not certain, but I doubt that power Windows and turn signals are on the same circuit using the same fuse, but it can be possible. The real problem with blown fuses isn't simply replacing it, but determining why it blew in the first place. Same thing applies to a sporadic turn signal. I would check all the connections and make sure the bulb has not jiggled loose. I have had that problem on an old Corsica that I had, the socket was just plain worn, and the bulb was loose all the time. Let me end my rambling by saying that checking connections, taking them apart and spraying with WD-40 and putting back together, and making sure that the wires are not getting pinched is about all a typical person can do without some serious troubleshooting.
