heater blower fan blowing fuses

[airkooledchris]

My heater blower just started blowing fuses.

I managed to catch it happening when I was just recording how the fan seemed to be working just fine.
It suddenly screeches, stops and then the fuse blows.

If I pop in another 16A fuse it'll run for a little while but eventually do the same.

Is this an actual issue with the fan usually, or something on the electrical side?

Thanks

Sounds mechanical. Bearing seizing up, stopping motor, which spikes the current draw, blowing the fuse.

In fact, it sounds exactly like my speedometer when it decides to start acting up. Colin the genius explained that the cause of the speedo noise was the speedo cable "stretching", with the end result being that the end of the cable driving the speedo was actually exerting thrust force into the speedo input bearing.

If the blower motor/assembly is user-serviceable, start servicing.
