Adjusting temperature on climate control system from cold to hot, or hot to cold makes a groaning noise. The noise occurs when changing temperatures on either driver and passenger side. It is intermittent, but seems to occur more frequently on cold start or cold weather. Sometimes it makes the noise when the climate control system is off.
Taken to two Lexus dealers, and have been unable to pinpoint the problem.
