    My AC is blowing warm. The last owner took it to the dealership and they said it’s not getting power to the AC compressor and that I would have to replace the AC Integration Control Panel.They said just the part is $600.

    I’m trying to find other sources, but I’m not sure of the part number. Tbh, not even sure what it looks like. I tried looking on eBay but different parts come up. Can someone please link me to the part, new or used? Or provide part number so I can search? Thanks

    Thanks, I thought it was that but I wasn’t sure if that was just a trim panel or if there is supposed to be a computer module or something that was supposed to be attached to it.

    I checked the fuse and it’s good.

    That's just the faceplate for the center of the dash. It lacks the controls bolted to the back of it. I just bought the same piece in woodgrain and will need to swap everything over. I think you may actually be looking for the control module that bolts to the back of this face plate.

    However, the 'compressor not getting power' is suspicious to me. If anything, I wouldn't trust the previous owner unless they showed me proof. IF it's really a case of compressor not getting power, that sounds more like the job of a relay than it does a control module, though it could be either, and it could also be neither!

    I'd rather investigate whether (a) there's a relay being used to kick on the compressor and replace, relays are way cheaper, and (b) I'd also test low and high side pressure to make sure things are at expected pressure, since the compressor won't kick on if pressures are too high or too low, then (c) many vehicles have a way to engage the clutch/compressor using bypass, I would try that here to see if the compressor kicks up and blows cold air.

    $400 is a lot of coin to spend on a previous owner's story.

    PSS: If you really want to test if it's the panel, find a junkyard near you with another 2000-2002 and grab the center panel, since I doubt you'll find just the control module. You can probably resell the trim surround on eBay for double what you pay for the assembly at the JY. I doubt you'll pay more than $50 for the assembly at a JY.

    This is from the dealer. I contacted them through email to ask for the part they were referring to. Still waiting. Fuse is good, I’ll check the relay in the morning. The AC button does light up solid and is not blinking

    there’s no junkyards around me with any parts for tundras. They say that it’s rare they have them

    I checked the AC fuse and that’s fine. Do you mean the heater relay?

    I found this,
    AIR CONDITIONING OPERATION
    When the blower SW is on, current flows from the GAUGE fuse to the HEATER relay (Coil side) to TERMINAL 3 of the blower SW to TERMINAL 1 to GROUND, activating the HEATER relay. This causes current to flow from the HTR fuse to the HEATER relay (Point side) to A/C fuse to TERMINAL (B) 12 of the A/C SW (Integration control and panel). When the A/C (Integration Control and panel) is turned on. Current flows from the GAUGE fuse to TERMINAL (B) 4 of the integration control and panel to TERMINAL (A) B to A/C magnetic clutch. Causing The compressor to operate.


    So it’s,
    AC Fuse > Heater Relay > Integration Control Panel > Compressor

    right?

    So I got a hold of the original dealer and they said the part number is

    84010-0C031 and it cost $1400. Wow!
    It seems like it’s a discontinued part everywhere I look.

    Great idea. I just pulled the panel. Going to pull it apart and check it out. I noticed the a couple of the bulbs, there’s green paint and some of it is peeling. Is that a risk for future problems?

    Update: dang! Ordered a part off eBay and they sent the wrong part number. It plugged in fine, but the vents were too long and my radio and ac didn’t work when plugged in. The hunt continues...

    I thought for a minute it looked like the dealer charged you $189 to diagnose your AC problem.

    Is that Canadian? It costs $189 for someone to look at your AC system now? Wowza. Stearlership indeed.

    So I pulled it apart to find shorts or burned areas in the circuit board. I didn’t recognize anything suspicious.

    Apparently, for this part, there are many that look exactly like it, but there are like 7 different part numbers. Is there another one that can be used in place of 84010-0C031?

    When I did connect the one from eBay (84010-0c280), everything plugged in fine, but clutch still didn’t operate and my radio didn’t power on. Is it just a matter of changing out pin connections on the terminals? I even called the original dealership and said I was willing to shell out the $1600 ($1400 part + $200 labor) they wanted for the repair, but they even said the part was discontinued and they have no way of getting it.

    You should contact @Roman to find out the correct part number. He can probably help you track down the right part number, you'll pay less at his dealership for the part than at your local dealership, and using a special code you can shave 20% off shipping, hit me up if you're unable to locate the code.

    Personally, I'd just hit the junkyard, but that's just me.

    I already tried and he said he couldn’t help. No luck with junkyards locally and I e even called random ones out of state.
