I've enjoyed watching a lot of your videos on how to diagnose problems and they have helped me so much. I'm currently stuck and not sure how to proceed. I did my checks of the fuses and relays in the engine bay fuse box and have power to all the fuse that should have power to them without additional switches needed like the AC or heater and they check out fine. The relay have power where they should but the main relay has .13 volts on I believe pin 85 and the F/BLW relay has 3.3 volts on 85. Having trouble finding info on the specific systems they control and such so I can find where the short is. Any help or information would be greatly appreciated.
