My 2007 Dodge Caravan's locks open on the left side and the tail light flashes on one side when I press the key fob. If I stand immediately next to the right side passenger door and press the fob twice then the right side unlocks and both tail lights flash. Today the Malfunction Indicator Light went off. I was low on gas. Any ideas on what could be wrong?

First you would need to get the code for the ck engine lighth going on and ck for codes in the door module you are having problems with the tail light not flashing.
