When my module failed it left the heater fan blowing even with ignition off and key in my pocket. I don't know how else it fails. If you disconnected the module and the fan stopped, it suggests the module is faulty but have you checked the factory service manual - the electrical section will tell you how the circuit works. It's extremely difficult to look after a 20+year old Corvette without owning the factory service manual!! I would just mention that one night I leaned into my vette to get something and heard a short brrt, about 10-20 seconds later another brrrt - it was the power seat trying to move back, probably to finish an adjustment made earlier that day. When I move the seat now, I always finish by moving it the other way a few mm, to make sure the switch is off. I mention that in case your power draw could be something else.

After many days of searching and unplugging things, and re-plugging and removing bulbs etc etc, i finally disconnected the blower fan module (that you have at this picture http://robhealey.com.au/Corvette/wp-content/uploads/hvaccontrol1-600x450.jpg) and finally joy, the amps that were being drawn, stopped being drawn. now i bypassed the actual blower with the meter to find that something before the blower is causing the draw of amps. so i am assuming its either the module, the ECC inside the car, or something else. any ideas? or any ideas on how to test the module? (its a 6 pin module). I live in the UK so its not quite so easy to pick up a new module to replace it and thus expelling the module as the problem. Cheers in advance Hi, I have an 86 corvette and i noticed that after a couple of days of no usage, the battery was drained sufficently enough not to allow it to start, unless i jumped it.
