That makes sense. The inter-web was full of info (mostly good) regarding this issue, main points were making sure the blower motor fan was clean (lots of crud slows it down) and making sure the air flow was unrestricted in hoses etc.
As it turns out, when we tested the switch with an ohm meter, it was definitely faulty, the action inside the switch was pretty "crunchy" and the circuit was intermittent at best. (Much better than finding something only slightly iffy and not knowing if you've found the problem
All cleaned and reassembled now and working like a champ. If we ever hookup in our neck of the woods,we can at least keep you guys warm and dry!
