    For some reason when I went and checked if the mod was working today it worked perfectly... maybe I accidentally had it on max AC last time or something.

    Really liked my old Mazda B2600 better. One knob to direct output, 1 to switch outside air vs recirculate, temp dial only controlled heat, and an a/c on off switch.

    Full Control.

    Did this mod tonight. Hardest part on a pre 09 would be getting the pin out of the connector. You could use a "greenie" or Xcelite R3322 to push the pin out from the crimped part that was behind the white plastic clip.

    Hardest part for a 09+ owner would be to read the big red bold text about 2009+ owners... I used a red 3M Scotchlok IDC splice to tie the green wire to the pink.

    I live in an area where the AC is sometimes needed with defrost and other times it's not. Toyota should take a lesson from Honda and turn the AC button light on when defrost turns on the AC and allow the driver to turn off AC by pressing the button even when in defrost.

    I have a 2014 DC and tied the green wire to the pink wire, verified 12v on the green wire by piercing the insulation and measuring voltage. However, now AC won't come on with the AC button pressed. The indicator on the button doesn't come on but the engine RPM doesn't increase, I don't hear the compressor clutch and it took forever to defog tonight on a cold wet night. Any ideas?

    My A/C did not work when I first needed it, many weeks after doing this mod. It turned out that the A/C fuse in the engine compartment needed a little push as it was not seated all the way. I know, this seems unlikely to co-inside with what you were doing, but it's easy to check.

    I checked the fuse and it was good, figured somehow I could've blown it during the change but nope. Reseated it and still no AC. Verified 12v DC on the tab of the scotchlock and verified 12v DC again on the green wire. I'm sort of stumped now.

    I verified 12v on the pink wire, removed my scotchlock and solder spliced the green wire to the pink wire. I can see the AC clutch engaging when the AC button is enabled but sitting at idle it turns on/off/on with the AC button on. I guess it modulates based on something, outside temp? Seems to be working now I'll see how the defog is in the morning.

    The AC clutch will cycle on and off as needed automatically as it controls the system pressure. When you first press the button, the clutch should engage and then it'll cycle on and off as needed.

    Thanks for 'fixing' one of the few things I didn't like about my new truck.

    Something interesting is last night I turned on my fan, slow speed first click,
    went to defrost/foot and I can turn my A/C off? at least the light wasn't on.
    I also went to defrost only and it still didn't come on.
    Went back to dashboard vents and then back to defrost and it turned A/C on
    automatically however I could turn the A/C on and off at will.
    Now in defrost modes I COULD NOT engage recirc...:annoyed:

    Did they maybe change something for 2015?

    What a concept, huh? I'm sick of vehicles "thinking" for the driver. Like my dad always said, if you make something idiot proof they'll make a better idiot!

    I wasn't sure if my truck was doing this (since the AC light wasn't on) until I left it idling while I was shoveling snow the other day and I heard the AC turning off and on. This mod gets done tomorrow.

    I understand that. And when the windows start to fog up inside I'll turn on the AC. When it goes away I'll turn it back off and enjoy not wasting fuel and the slight HP increase.

    I know what my vehicle needs. I don't need it doing things for me.

    The ac is on to dry the air. It removes moisture from the air going into your cab to help with drying up your Windows if they're just foggy and not icy. Without the ac on you can cause your Windows to fog up in certain situations. It really shouldn't be on all the time, it's a huge waste. I generally cycle it on manually every 10 mins or so just to keep the condensation off the glass in the winter. Good mod. I will do this very soon.
