A/C hot on startup, then cold. Normal?

I’ve developed a couple things that I tend to do to help combat the whole hot truck and takes awhile for the AC to catch up.

The window vent things so I can leave the windows cracked open and not worry about rain. This is a massive help on hot days and leaving the truck parked in the sun.

If I’m not in a hurry to go, open the windows and leave a door open for a couple minutes to help vent. Even better is to start the truck and turn the fan on high for a minute before engaging the AC and give it a minute to get all the hot air out of the vents before getting in.

Tint helps cut down on solar heating in the cab.

Yep, I always leave my windows cracked in the summer on my 93 Ranger. I have the window rain guards, I'm not too worried. Also that windshield solar thing works great too. Parking in a shaded area is also a big plus.

FWIW, my son and daughter have those AC issues when it's hot out and they are in idle or stopped at a light etc, one has a Mazda, the other a Sonata.

I'm gonna look into if the radiator fans change speeds when the AC is turned on. In what I had read some cars that only have one radiator fan. However when u turn on the AC that one radiator fan now goes into a higher speed.

Some cars also have an electric pusher fan that kicks on to help cool the AC condenser

Now I’m trying to remember which manufacturer has (had?) an automatic solar powered system to open a small vent and run a fan to keep interior heat down when the car was parked. Seems like something Mercedes would do.

Yes I know. Thanks

That's what I do. AC in my 98 hasn't worked for over 20 years. Don't miss it. I'm a windows down type of guy, no matter the weather. Even though the AC in my 04 Lightning works, I rarely use it. Couple times a year to keep things fresh. Otherwise, windows down.

My F-150 will blow snowflakes out of the vents in AC mode. I rarely use it, mostly long drives or traffic or hot and humid with rain. Even a lot of long drives if it isn’t miserable out, the windows are down and the wing vents open. I’m a little irritated that my only rigs with wing vents are my F-series trucks and my 88. I’m intending on swapping to wing vent windows on the Choptop and if I fix it the 92. A little bummed that’s not an option for my 00 Rangers.
