hi everyone i have that po449 vent solenoid also dealer wants 267.00 for the part what a crock they dont even know what i really want i told them it's a small connecter circuit nad they say nope i agree with everyone on here that chevroley should pick up the bill for all these issues due to its mounting location they know all about it and even offer a NEW version and new mounting location..why should us consumers of chevrolet products bail them out of trouble if they dont want to do anythnig to help us gmc chevrolet owners out i think im gonna post gm see what thy say then i will post it here for everyone to see what they have to say..
