Whenever your fan works on high, but not on a lower speed, the problem is almost always that resistor. Tim


What does the resistor look like and is it still available from
toyota? I swapped that silver relay from van to van and it didnt make a difference. Then i let the van sit for days and started it up and put the fan on high and it turned on only on high. So im pretty sure its the resistor. Anyone got a part number?
