Just an update, spoke with Brian from GL re: the HVAC/AC motor resistor. There is a "Service Bulletin" published by Lotus already, so these will all eventually get replaced on the Emiras. However, there is not available stock on the revised parts yet, so GL is currently replacing any faulty resistor with the same part as before, and we'll have to go back to get the 'updated part' once they become available. He's had 2 replaced already, I'm the 3rd, the other 2 hadn't seen the issue come back since replacement.
We'll see what happens with mine. I wasn't planning on driving the car through the rain, but I may do this now, just to see make sure this part doesn't die again. Would like to to get these things address while we're still in warranty period, so I'll probably be trying to put more mileage on the car until then, to make sure no other issues come up before the 3 yr warranty expires.
