with great appreciation to all who put some thoughts here,i went to buy the relays for the auxiliary fan,and since the parts dealer is a friend of mine,he allowed me to test if the relays are the culprit,put new ones in no go...i returned them and for curiosity reasons i double checked on fuses 25 & 29, i found 25 had a small crack,there was a spare fuse,replaced the cracked one and there you go fan z working,problem solved...
Moral of the story: next time if you want to check the fuses,do it in broad day light
