I bought a spare a while ago, have u tried ebay.

If i needed to drive the car, i wouldjumper the fan to 12 volts wiwth a dropping resistor, big one like a couple of paralleled headlights or a big **** resistor, say 1 ohm at 100 watts. Could make resistor out of wire as long as it did not melt items nearby.ww your on the moon and cant come home till u fix it. Watta you gonna do?
