Radiator fans stopped working.

T/S 'ing lead to relays (not in main panel nor dash panel). I'm not able to locate "J Block" fuse panel w/o tearing into the guts more. Ie.. I believe it's under the main fuse block housing., Visual inspection has me thinking at minimum a fender brace has to be removed. I am within walking distance of an open parts store. T.I.A. Moderators, this is a great site!

fans should have a small relay box under the hood behind your main underhood fuse box towards the firewall

The electric coolant fan relays , underneath , buss bars are totally corroded and need to be replaced ! Saw a relay upgrade for my year &model truck , an upgrade for the relays on E'bay. Will they work ?Is there a wiring diagram for it ?

Mice get on top of the fan fuse block and pee on everything. Which corroded the bus bars and contacts were 10 A fuse sets. How can you bypass or splice in a 10 A fuse.
