Intermittently when air conditioner is operating, we get a noxious chemical smell from air vents. Odor lasts for several minutes. This is not coming from outside because we are circulating inside air. We see no pattern to this. It happens at times when the temperature is very hot and also when temperature is moderate. We have had the Montana to the dealer three times. They cannot come up with any fix. We are concerned that this may be detrimental to our health. The car stays cool, it's just the awful smell. The cabin filters are perfectly clean.
