Check the Relay located in the Fuse Box - Should be K24 Relay - or see the bottom of the fuse box cover.

hopefully this helps

 

You can check the K24 relay mentioned in the prior post by checking Fuse #4 for battery voltage. Also check fuses E and F. If all of these are fine, then you need to check inputs to the controllers and outputs from them. Email me for a schematic.
