97 bonneville SE radiator fan keeps blowing fuses.

Does anyone have a diagnostics and/or wiring schematic for this. Keeps blowing the 40amp fuses on short rides thru town.

How long does the fan run before the fuse pops?

BillBoost37 is a glorious beacon of light

First up is to unplug one fan and test, then swap which is plugged and unplugged. I think you might find the resistors on the back of the high speed fan is bad. Best I can do from work w/o the manual.

The fuse blows after approx 5-10 minutes running. And that'* without the AC on. If it'* the resistors on the high speed fan. Can they alone be replaced on how much are we talking? Thanks

If it'* the resistors..I'd get a different set from a junkyard. Shouldn't cost much.

Why are the fans on in the first place if the A/C is not on? That does not sound right? I am thinking you may have a little more on your hands than some resistors :?
