Hi folks, I'm looking for a solution to ventilate the car interior during occasional camping trips sleeping in the car with the car off (not suitable to leave car on in some situations). I know window screens and rain guards are commonly used by I'm keen to find a simpler closed-window solution. I found this page Prius camping that showed a controller solution to run the existing dash blower fan controller via a custom built PWM curcuit, however, this is beyond my capacity to engineer. I was wondering if a simple eBay or other PWM controller could be wired to the blower motor directly to bypass the existing fan controller? Or perhaps might there be a way to run the battery cooling fan, if it does in fact vent air outside? Thank you for your input!
If you're driving a 2004, I'd think you could build the exact circuit hobbit engineered on that page ... he gives a schematic with the parts identified, about halfway down the page. If assembling it seemed like more than you were comfortable with, I wonder if there'd be a way to do a "WTB: assemble this gizmo for me" kind of post on PriusChat, maybe attract some young poster who likes to get soldering practice. If somebody contracted a small-scale assembly outfit to make a small number of them, I wonder if the PriusChat Shop might agree to carry them. -Chap
