Same as my Express van when it was newer at highway speeds anyway. Always ice cold with a properly performing system especially after GM put the 11 bladed fan and matching clutch on it back in ~1998 after numerous complaints from my dad that the ac sucked around town and the engine ran hot.Fantastic ac too, best I've ever had. I was getting 38f air at the vent in 110f heat when I first got it

I will say though my mom's 2019 Titan has the quickest cooling, coldest factory AC system I have ever been around. On a 110F day it will hold upper 30s at IDLE with the blower on highest speed. Within a few miles you are knocking off recirculate because it gets so cold on your finger tips. The condenser in that truck is HUGE and it uses an EV fan clutch with a massive clutch fan. When the ac is working hard to cool the heat soaked interior the clutch fan roars in it even with a cold engine.
It’s been a few years since I looked at it disconnected, but I think it connects the inlet to the outlet flow on the engine side of the valve…the same as looping the two hoses together.I will be adding two pusher fans in front of the condenser, once I get some more idle amps from the ad244. I am aware that GM used a valve on later trucks, not sure how that system works though. Does it shut off flow or bypass? Where does it bypass too?
If it bypasses from the inlet hose to the return, it would need two shut off valves, which would seal off the heater core.
Vacuum, by the truck's HVAC controls (when equipped with this feature.)Does that valve operate electrically?
That's good to hear. When I was a Nissan tech back in the late '90s, we had customers who would buy a brand new black Nissan Maxima and then complain the A/C wasn't working. Dude, you bought a black Maxima in Oklahoma. The windows aren't tinted, you're leaving the sunroof shade open, and you're parking in the middle of the Wally World parking lot with no shade around. Then you jump in with the windows all the way up and you're expecting 30* air immediately? But they weren't wrong. I think the A/C systems were sized for Hakkaido, and not the American southwest.I will say though my mom's 2019 Titan has the quickest cooling, coldest factory AC system I have ever been around.
