anyone know where the asd relay is located on this van? also when using the turn signals the light on the radio flashes, when applying the brake the light on the radio goes out???? thanks for your help

 

have you been doing any rewireing in the dash? it sounds like power was tapped from the wrong place.

If you disconnect the grey 6 position connector on the drivers side by either the A-Pillar or by the bottom of the B-Pillar, you can check for continuity witht the radio lighting circuit. That connector carries the wires for the rear lights. Another place to check from would be the colums switch control.

The other thing to know is if all of the lights on the dash flash slightly...which just means there isnt enough current to go around because of a bad connection.
