Air Con PCB - 97 Grand

[paulgreen]

Hi to all,
The little PCB that controls the fan has burnt out on my system It has what appears to be 20Amp cable coming in to it and one of the connection pins at this end has burn out off the motherboard. The multi meter still confirms connection through all circuits apart from the lack of negative input pin. Do you think if I soldered a length of 20 Amp wire on to the PCB and connected it to the car with screw in connector blocks it would be ok? Better than the over-priced £100 I've been quoted for a second user one over here!
