we my old man has a prob with the vs blower fan,
it keeps blowing fuses
he beleive it only blows when he has the thermo fan on and the ac at the same time

i have swapped the square relay/resistor under the cowl panel and changed the fuse and it was fine. few hours later went for a drive and blew it again

beside the obvious its shorting can anyone guide me in a genral area

its had the thermo connect to under the ecu
and its also hand the level3 cluster up grade
which all was fine for 4-5 months,
