Making the Polaris Heater Blow Both Defrost and Floor
I just bought a 2015 RZR Sunset Red EPS 50" Trail. Very excited to get it back from the dealer with the accessories installed.
The Polaris heater unit (2880534) doesn’t look like the picture in the Polaris accessory catalog. The new heater unit only blows one direction – onto the windshield for defrost. I’ve been told that some people have reversed the connections to the heater fan permanently to make the heater blow air down onto the floor which is a much more effective way of heating the occupants.
One modification I am working on is to install a dash switch (a basic on-off rocker switch) to controllably reverse the polarity to the fan on this unit. This will work by using a SPDT relay to each of the two fan wires. Assuming this works properly, my dash switch will control the direction of airflow – up is windshield defrost, and down is floor heat.
