I have a 2000 Ram 1500. It sat for a couple months while I was out of town and now that I am back there are a couple of problems that were not there before I left. When I first started it up I let it run for a bit to warm up and then when I put it into gear it was a little hesitant but didnt take too long to act as normal. When I got on the road I noticed that the speedometer was not working at all and both the ABS and Brake warning lights were still lit. I took it out on the highway for about 20 min to see if it would work it self out but no change. I also disconnected the battery to reset the computer but still no changeā€¦help!
