2000 Bravada no or very little power to anything electrical. cant find anything loose or unplugged . i was told it could be a ground issue but i can not find a ground for the wiring harness in the vehicle. ive checked the ground wires under the hood they seem to be fine.i just replaced the heater core so it must be something in the dash.
A ground that is bad will show little power, but so will a bad live connection. Check the starter connection from the positive battery post down to the starter, and look at the connection, both going to and from the terminal. If all is ok, there should be a ground wire from the engine block to the car body also. If not make one and install it. good luck
