2002 Pontiac Montana Owner Comments

problem #3

Montana 6-cyl

The windshield wipers freeze up in the winter, making it impossible to see. They are recessed down too far and receive no heat from the defroster to keep them from freezing up.

During cool or cold moist days windshield defroster system will only clear the passenger side and about 50% of the driver's side. The dealer states there is no fix. I have had three near misses because I couldn't see a vehicle coming from my left front.

Problems with vehicle windows fogging up. The consumer's wife was driving where she felt a draft on her legs and set the recirculation mode to inside air and set the blower on #two. All of a sudden, all of the windows fogged up. The blower was turned on high, the defroster were turned on which cleared the windshield. The dealer suggested that something was wrong with the heating/cooling system. The consumer was advised that the recirculation mode should not be used unless the temperature was extremely warm and should always be on fresh air mode. (this was not stated clearly in the owners manual)
