I think my silver control box is not working. When I jump across pins 1 and 4 on harness B that goes in the silver control box the diesel burner motor goes on and fuel mist comes out of the nozzle.<br/><br/>The Webasto part number is 287.962. Does anyone rebuild them for a reasonable price? It appears that Webasto number 9028629A may be an upgraded replacement. Does anyone know...
