You can put a current sensor on the wire going to the fan. That will tell you if the fan is running, or at least shorted till the fuse blows. But you also need a sensor for the A/C being on, and the fan goes on always with it. The REAL problem I see is fixing the steering wheel being on the wrong side.

Thanks for all the comments and thoughts.

I suspect most (if not all) commercial after-market fan controllers can fail if the sensor becomes disconnected.

If they had some intelligence, then you would get a warning before it is too late.

Modern instrument panels illuminate the lights at power on, but in reality how many people notice if one or more are out. [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-4f6a0e3c-9c00-4035-943e-772b5a9debb0/contentimage_5F00_4751.png:16:16]

Video added.

I've duplicated the functions to demonstrate it working.

Not sure where I grabbed that copy of code, but I'd forgotten to declare the Start Button, so I've edited it and placed a note.

Cheers

Nice project. I particularly like the introduction of the fail safe mode to turn the fans on.

Thanks for posting.

Kind regards

Hi Mark,

A totally cool project that solves a real world problem. I really like the way you think about and plan for all the real world problems that can occur. This type of anticipation of failure can only be earned with years of experience. Thanks for sharing yours with us.
