Cooling/demist fan 2.

Better shot of anti skid tape. It is stiff enough so it doesn't slump.
I fooled with 2 fans spaced the same as on instrument module and same distance from windshield in my car on a night when things were fogging up. True nowhere near as effective as high speed hot and dry, (AC on), it did make 2 holes you could see through. Any heat would be a benefit. Also put a piece of plastic on the back side of instrument module to replicate firewall and used two 1500 watt electric/oil radiator style heaters to heat up module, pretty easy to get 140F. With 4 fans even on low it dropped temps fairly quickly.
