I don’t mean to bring up an old topic but I saw the thread from a different forum. I am having the same issue as you all mentioned. The temperature was mid 90s and car ac ran great while driving. Got to a stop light and the fan speed began to fluctuate by itself to a lower speed. A short drive down the block I pull into a parking lot and I notice a white smoke/vapor coming from the engine bay. It also created a sound when it did this ( I’m assuming it’s a blow off valve or something for the pressure). I thought it may just be the hot day but I tried it again a week later when the temperature was 85 degrees out. Car started and idled fine. Took it for a 10 mile drive. The ac was cold and stated on 12 fan speed. Pulled it back into the garage and again acted up like i mentioned. Passenger rad fan is spinning when AC is on. I have a video clip of the noise it makes when it release the smoke/vapor. If you guys have a fix or knowledge of what it is please let me know. I just bought this car in April and this is my first “issue”. Car is an 04’ with 28k miles
