I have a 2019 Defender CAB Model with factory installed heater. Has anyone used their side by side at temps zero (F) or below?? Does the defroster vents work ok?? It doesn't seam to blow very hard out of the defroster vents I've noticed.
You sometimes have to close the lower vents to blow more air out the defrost side make sure you get the ones that blow on your feet also for maximum effect. Also order can ams winter kit that covers the radiator.
