Do you mean 3.75A or 3.75 V across the fan?

Since this is an aftermarket mod there is a long list of what may be 
happening.  Without knowing how your circuit is configured I can't say for sure what 
is going on.  Is you fan controlled by a thermostat alone or is there a relay 
involved?  From where are you pulling power?  Is there anything else that is 
staying on?  Lights?  Radio?

What happens if you unplug a wire from the thermostat?  From the fan?  From 
the power source?

I need more information.
