Fan blowing full speed for a split second

mrpcar · 01-20-2012, 08:37 AM

I can almost reproduce this weird symptom every time now.

Only happens when I quickly accelerate up to 100+ mph, HVAC vents blows full blast by itself for one second and then back to normal speeding setting.

Anyone else experienced this?

I did. Went to a stealer a few times with it, says it's normal. Mine does it on the lowest fan settings, AC off. It's trying to get to that temp set point asap, that's why it blows for a split second and back to normal, thats what they told me.

Doesn't sound right, even my stupid Italian car don't do that...

its blowing wind in your face so you feel like you are going really fast already so you slow down ;-)

In my car it does it only when AC is off with the fan is set low and the outside temp is exceeds the inside set point by a degree or so.

Honestly the AC just seems to be all over the place on ours. Rear climate changes have a huge impact on the front climate. Dual zone doesn't work. Passenger can't get heat at all if the driver is using AC. Had it to the dealer and they pretty much snowballed us out the door.

The X5 climate is just full of gimmicks. Briefly blowing fan, AC, noisy fan motor, noisy electronic coolant pump. This X5 is our 3rd. fully loaded BMW and first with climate problems!
