hello all, this prius man. jeez. first off, should the ac compressor be running when my defroster are on? it makes the air cold, which is not ideal in the cold weather. secondly im missing a nut and bolt for one of my engine mounts. and finding part #s for this car can be a pain in the nice person at times. maybe someone could help, its the passenger side one on top. finally im suspecting a blown head gasket? or maybe a cracked egr cooler, im burning coolant, no over heating or boiling over out the overflow. i have a p219a i believe it is. what a pain. hope everyone is well
