Where is the orifice tube located on our jeeps? Is it in the accumulator? The bottle thing near firewall.
Also, does yours get cold in fan 1 recirculation on highway at night with like say 85F outside temp? The reason I'm obsessed with all this I have 3 other vehicles and they all would freeze you out at night on lower fan speeds even. The air is cold. The jeep is just cool, comfortable but not COLD. Why? Is it an inherent weak designed system or is there something more? I just want her to be the best that she can be and I'm happy. I still suspect something not right. Perhaps orifice tube not letting enough freon through fast enough. My bmw will freeze you out at night after driving a while, even on minimum fan. She may have a variable displacement system with an expansion valve. The Tacoma 2000 has a simple cycling system, and it gets VERY cold on the highway. Noted smaller cab but the air temp just gets icy. Finally, I have a mini cooper that will also freeze you out lol, but not as strong as the other two just mentioned. It has a cycling system too the fan will go on and off so I think compressor does also. Jeep is most weak. The BMW is cool it continuously varies the fan based on output pressure. That being said like today at 99 it was barely keeping up to keep car nice and cool, required full blast nearly. That's not normal either for a new bmw, this one is old. But it does good and freezes you at all other times so that's good, that tells me it's just at its max capacity of cooling with it's old inefficiency's.
Thx for putting up with my OCD
