Mitsubishi Montero Gdi 1.8

Hello everyone,

I have a problem that I see in the forum, it is vast common.
Well, my case is the next one, when I go in 2h the green lights of the rear wheels do not light and the light of the blink. If I put 4h it works well on the 4x4 and the lights of the front traction are lit the rear the rear the rear and the one of yellow lock flashes. And if I put the one that blocks the difest the HCl I think ...... The rear do not work. A greeting
