99 3.2 TL - A/C heater fan not doing anything - HondaClub.com

Without warning or noise, the fan has stopped working. All fuses are good, circuit breaker swapped and Ok, heater relay jumped and no change. The fan bench tests OK, there is a very weak 12V to the fan motor but will not light a small test lamp.
I suspect the "transistor" is bad as the power side is an open circuit (no ohm draw).
Is this common or am I missing some subtle problem elsewhere? Anyone elsa have a fan go out and how was it fixed?

All suggestions welcome.

check to see if the connector is melted at the fan connector and if it is melted their is a repari harness for that and if not i would power the blower motor the transitor is not to common like the blower motor or harness.
