Land Rover Repair: air conditioner blown fuse issue, blown fuse, blower motor

Question
The AC 30A fuse blows.  Sometime right away after replacing the blade fuse, some times it does not blow for days.  1998 LR Disc 1.
Is there a schematic for this system?  My mechanic here in TX wants to see where the relays are and test.  If a schematic is available, how can I obtain it?  Thank you, Arthur

Answer
That fuse is almost certainly failing because the blower motor is tired and drawing too much current.  When that happens you can damage the control panel, melt wires, and get a host of other troubles.  As to schematics - Pay $18 for a day's access to Land Rover's official service support site - www.landrovertechinfo.com and you can get every piece of service info for the vehicle.
