Hi All,

Took car out for a nice long drive to Oxford in the beautiful weather. Was so hot even with the roof down that I had the fans on coldest setting (non-AC) and full blast.

On the return leg the fan/blowers completely shut off and would not work on any settings.

Could this be a blown fuse in the first instance or would it more likely be the heater blower/matrix?

Thanks

Blower might have shat itself.
Fuse likely - but also check the blower resistor (although when the blower resistor soils itself it commonly works on high speed only)

Likely a blown fuse if the fan was sticking somewhat and drawing more amps than the fuse can handle.

Thanks. Assume the potential culprit is no. 20 (30A)?
