This is my first winter with my 2018 GT. It is the worst vehicle as far as demisting goes. With the blower on a medium setting it only clears a very small section in the middle dash area, and on high it takes the engine forever to warm up. I live in Canada and with -18C this morning I finally scrapped the inside of the windshield after about 10 minutes of idling. I even tried the Meguiar's Anti-fog. spray and that did absolutely nothing.
I get the bit about the Diesel engine taking a while to heat up, so we*d be blowing cold air for a while. But why is the air-con not doing a better job? In previous cars, I*m sure that did most of the job of clearing the screen while the engine warms up.
BTW: My old Ford Mondeo Diesel had supplemental electric heaters that kicked in until the engine was warm!
Well. The latest on the (lack of) demisting capability is that Mazda say *this is a normal operation of the vehicle and not something we are able to change.*
I*ll next try when it*s cold and let the car warm up to 80 then try blipping the engine to +1200rpm & see what happens...
quick side question---have a 2018 grand touring here in the US. Do I have wiper heaters? How can I tell and how do you turn them on?? (I must have missed that feature reading the manual)
Thanks...I looked and nothing, so guess our GT did not come with it.
Figured it out...Grand Touring only have it if they got the GT premium package:
Active Driving Display (windshield HUD) with traffic sign recognition; Heated rear seats; Heated steering wheel; Windshield de-icer
So if you have windshield HUD, you got the de-icer...otherwise you don't.
