Be sure to check the connectors on your Relay # BDW42035 as to ensure everything is properly connected. On this particular relay the #85 connector is the input for battery power which goes to the switch on the #86 connector. This will activate the #87 terminal which gets power from the #30 terminal. Be sure to verify you are getting power to the switch side of the relay and the switch for the relay is not damaged. If there is no power on the switch side the relay will need replaced.
Please let me know what you have tested and found as well as exactly what relay you are working with so I can give you more specific information on your situation.
