Has anyone used OBD for colder AC?

Damn
We got the 19 Crosstrek and it’s better than my taco

 

This mod is worth trying my trucks AC is ok lowest temp I can get is always around 44-45
Id be happy with 40-42

 

I'm interested in trying this out, does the resistor really need to be 1/2 watt though?

 

I'm sorry, but whats on the end of that white plug? If those are wires going somewhere, I don't think the explanation of what the resistor is doing is accurate. I thought for a resistor to work as intended, it had to be installed in line of whatever you're trying to raise the resistance. Am I missing something?

 

Installing a resistor between the two pins will reduce the total resistance of the circuit by putting two resistors in parallel. Adding a resistor in series with another resistor will increase the total resistance of the circuit.

 

The AC system on our trucks is meh simply due to a small evaporator core size. Faking the temp sensor to read higher temps (so it keeps the compressor on longer) is only going to lead to you freezing moisture and blocking airflow through the evap core.

Leave it stock, turn on recirc and make sure you get the heat out of the truck (open your windows) before.

 

Really? Only ever felt like my blower is lacking if I try to turn on the dash + floor vents, and only when it's hot as fawk, or just starting out when I left my windows up all day... just the dash vents and max A/C (with recirc on or off) os plenty for me, although I have an access cab and not the extra greenhouse of a double cab.

Sitting in traffic kinda sucked before, until I went to an electric fan. Mucho improved at low speed with that, even with high humidity & 95+ temps it blows almost as cold sitting at a light as cruising down the highway... I was glad to have done that when the belated hot as hell summer finally got here last month.

 

I can vouch for this. I was overcharged on my 4Runner and experienced exactly this - freezing of the evap core, and almost no airflow until put on "fresh" intake to remove the frost.

 

This is starting to sound like less of a good idea.

 

What electric fan did you go with? I see LC engineering has a kit for the 1GR FE.

I used coil cleaner on my condenser this summer and it improved ac performance slightly

 

I did a spal pusher

 

I did the Flex-A-Lite replacement fan, although mostly for the MPGs, but I'll definitely take consistent A/C. It's not exactly cheap (especially after upgrading the controller, which I strongly recommend, I had 2 of the ones with spade terminals in my 1st gen, and both failed) and it's not exactly simple, but I think it's worth it. We'll see come winter, my mileage was awful last winter and I suspect a good bit of that was the mechanical fan.

Putting a pusher fan in front of the condenser works too, at least for the A/C, and it's cheaper and a bit simpler... although aside from having to mess with the overflow bottle, running the wire from the A/C head to the fan controller was the most labor intensive part, and you'd still need to do that. Only way around it is triggering the fan off the compressor clutch, which brings its own issues... that or wiring a manual switch in the cab, but by the time you go to that trouble you might as well just wire it up the right way.
