So you are saying if the interior is hot, it won't start (no crank, not even a click), but if you roll down a window and cool the interior down it does start? First, check you don't have the anti-theft system activated when this occurs. If you have any aftermarket items that interact with the anti-theft, like remote start, heat may be affecting wiring where those systems were spliced in. Second, heat may be soaking the starter or causing a intermittent component failure in the starting circuit. To isolate that it would need troubleshooting. (A bench test of the starter would confirm its operation.)
