hey huys, just kinda curious about something... the last few days in lethbridge have been on the cold side in the morning... i leave for work at 5am so its still quite cold out... i always start my car 10 mins before i leave... but it usually doesnt warm up fully until i drive it a block or two... but ive noticed on a couple occasions that when i hit around 70km/hr and stay at this speed i hear a whinning that sounds like its comin through my defrost vents.... this has never been a big problem and aways disipates quickly.... i dont think my speed has alot to do with it, but 70 is when i notice it.... any ideas on whats going on?... is it cuz shes still not fully warmed up?
