The mode control is under the dash.Its a little motor with a rod probably a green connector.You can get to it moderately easy.Some times thy stick or go bad.Flick it.Now their are several little motors under the dash and thy all look the same so flick them all(the mode,recerk,and temp control)

Sorry i can not get any canadian info on that.So i can not help you diag if flicking them will not work.
