so i wanna try to fix it myself, i see that radiator fan is not turning on, first i wanna check the fuse boxes, anyone know which fuse should be it on 4.7 engine

 

It should be in the PDC under the hood. On my 99 there's a diagram of the fuses on the underside of the lid.

 

soo after checking fuses i did find blow 40 fuse, called rad fan, i replace it with int light 40 fuse and the fan started working, now the engine light did not go out maybe have to cancel it first. question i have is do you think going thru that flooded water caused the fuse to blow? or something alse happened that caused the fuse to blow and this fuse will blow too..

 

It's very possible that the water caused a short that blew the fuse. You'll probably have to clear the code too.

 

soo replaced the fuse, fan started working fine, everything looks good. code after couple of miles went out, but when i check code with the ignition trick, code still shows, i guess i just need to clear the code with the reader
