Ground 2000 dodge durango
Ive replaced the battery and alternater it is getting the
right voltage... But the security light comes on and no bus
light comes on and all the gages stop working and the car
starts acting crazy what clould that be? And where does
the ground from the trans conect to under the car
You need to go through every inch of your wire harness checking connections and bad/frayed wiring, making sure all grounds are present and good, but even then "no bus" problems can be due to a bad computer module. You won't have the equipment to deal with that, it takes a dealership or very well equipped shop to diagnose that, my suggestion is leave this one to a pro and take it somewhere.
It has over 300,000 almost 400,000 could the vehicle just be done? I don't have the money for a pro or a equipped shop. The grounds are broke but we just got that to replace thos if that doesnt fix it. Could it just be quitting time?
400,000 miles? Yeah I'd say it's about done, if it was a simple fix sure, but troubleshooting electronics can get costly. Might be time to part it out or scrap it.
