I have one of those basic temp pbobs (think for your bbq grill) in the center dash. For the most part since installing the amp is has hovered RIGHT below 40F discharge. I did notice ONE time since installing it it was at around ~32F which shouldn't have ben possible......
Something in the back of my mind and which has been suggested elsewhere to me, is that the system is OVERcharged. Any thoughts on that? I do have the high/low pressure switch in the dryer.
