I lost 'ALL' electrical power to the van. I drove into the driveway and the van just completely shut down. There are no lights, radio, power windows, horn, or no noise when trying to turn the key. I tried to jump start, but it would not work. I had the battery tested and it is good. What could it be?
Check the battery terminals. Make sure they are clean and tight. Also check the fuses. There may be a broken or shorted wire some where in the harness. Your best bet is to take it to a qualified mechanic so the issue can be properly diagnosed.
