Hi, strangely enough I was thinking along these lines but was thinking of a fan which would just plug into the socket and work as I drove. However the real problem is heat build up in the car when it is standing in the sun. I looked on line at solar powered fans which extract the hot air when the car is parked but reviews suggest that they don't work very well. I am thinking of buying an interior windscreen cover to see if this prevents heat build up. Leaving the windows open must work as today I forgot to open them, jumped into the car and within half a mile the hazards were flashing. Simple cure, pull into side of road, open all windows, put blowers on full. Within 10 minutes hazards OK and stayed off the rest of the 20 miles I drove. Bit of a pain but liveable with.
As there is no problem when the weather isn't hot, I don't think a BSI re-set will help you.
Strange one, this. I am tending to think that there may be a 'dry joint' on the BSI board that
is affected by temperature. If you're up to pulling out the BSI when this fault occurs you may be able to
isolate it by gently tapping the components with a plastic tool or your finger tip where you can reach.
(Or you can do the same when the fault is not apparent and see if you can make it appear.)
Oh...a 'dry joint' is a poorly made solder joint that does not bond to the PCB track correctly.
