Shouldn't happen.My AC works well when I'm just cruising along, however, if I'm driving like an idiot and flooring it from every light (hey, sometimes I get in that mood) it will blow out hot air for about 5 seconds. Then it will go back to cold air. It's a very noticeable difference in the temperature of the air. Does anyone else experience this?
When you floor it even if the pump switched off for a while the evaporator should be freezing cold.
2 things I've noticed.
The Aircon is mediocre for this car. (Sucks)
When the car has been switched off for a while heat from the engine is somehow getting inside the ventilation system and when you first switch on the car there is a blast of hot air for a few seconds.
