Here we go again..LOL

It's perfectly normal..it's the HVAC system's cabin air sampling air pump..there is a little vent just to theright of the steering column on the knee bolster (Left hand drive cars)..it shuts off after about 10 or 15 minutes and turns on as soon as you open the door...


NOTE to Jim..this would be a good item for the FAQ section.
