I am having trouble with the left turn signal on my 2000 dodge intrepid, and just can't figure out how to fix it.

When i turn on the left turn signal, both the front and back turn signals flash, along with the tail lights, and the front right turn signal. Also, the clock flashes along with the turn signal when it is on.

When the lights are on, the left turn signal stays illuminated on the dash and the turn signals stay illuminated the whole time as well.

None of the bulbs are out, as i have replaced both the front and rear turn signal bulbs on the left side, just to be sure.

Any thoughts on what this could be? Any help would be greatly appreciated.

Thanks
