Here's some vent temp feedback after sitting at work all day with all 4x windows cracked about 3/4" and 105F ambient temp. I opened the driver's door and left it open for about 1 minute, open and shut the rear door to toss my backpack in, otherwise did not vent the truck as usual (roll down all windows and lift the hatch to let the heat escape). All the figures below are based on the lowest temp observed. The compressor cycling caused a deviation of 3-5F in all conditions.
I have a new 12" SPAL 12v fan on order to replace the 12" SPAL 24v one running now. It should be here by Saturday. I'll throw it on and do some more testing. I'd like to see the idle temps a bit lower for when I'm out wheeling. I'll also tie in the Trinary switch/automatic fan function this weekend and report back.
In all, I'm very happy with the results considering I am fairly new to full AC work and I suspect a shop may get it down a smidgen more but I'll take this over the 20F higher temps I've had all summer! I'm half tempted to take it to a pro shop and have them evac and charge to see what they get but I'm poor now.
