I have a 2003 Dakota Quad Cab 4x4.
My issues started when my battery went dead for no reason a month ago. I removed the battery to charge it and have it tested. It tested fine and has worked since.
However, since then my dome lights flash when the door is opened. I hear a clicking in the engine compartment. And my door locks work intermittently. Sometimes they work from the key fob, sometimes not. Sometimes they work on the door switches, sometimes not. Sometimes they work with the engine on, sometimes not.
I have checked all the fuses that I know of. I have not changed, worked on, or added anything to the truck.

Thanks.
