2005 Dodge Neon rear turn signals, break lights and rear ha

I have a 2005 dodge neon and I'm having an issue with my rear turn signals, break lights (including center brake light) and rear hazard lights. None of those lights are working. It first started out on the passanger side rear turn signal and then when I went to go check if it was the bulb the other side and center went out. Both bulbs seem fine and the filament is not burnt out or broken. One side came on for a bit but then hasn't worked since. I've checked all the fuses and they all seemed fine. Also the ground wires seemed connected. My check engine light came on for a day but by the time I was able to go get it checked it went away but the lights still didn't work. I would appreaciate any advise as to what the problem may be. Thanks in advance.
