Hi Tavnav, I had this problem with my D40 as soon as i got it. The problem comes from water getting into the transfer box through the propshaft seal and damaging the switches. If you drain the transfer box and the fluid that comes out is a cloudy pink colour instead of red this is the problem. Alot of people just replace the switches and this cures it but this is only short term and the fault will reoccur unless the seal is replaced, it's not a big job to do all in it will take you about an hour. Hope this helps :thumbleft:
