Thanks Tone and Anita,

You were right ! The problem was exactly where you pointed out - driver side wire snake got short going into fender (?) so Peter's Isuzu (New Hapmshire) took care of it and charged $75 for one hour of labour and $2.25 for shop supplies (read : wire )
What was interesting I was blowing the 15 amp fuse by turning to the left only. Turning to the right did not cause an problems (makes sence - since left side was shortened). After the fuse will blow all gearbox lights will go and gearbox mode switch will start acting - loud bang and yank going from the second to the third gear. Ofcource all that had dissapeared since electrical problem went away. My extended warranty company (WarrantyByNet) said that they will reimburse me for the full amount of repair. Well I guess we will see when this will happen.

Again, thanks to everybody who jumped in with good advice !
