Where is the mode door actuator located?

Hi Joe,

Yes, I see that’s the only one up there. I removed that, and the part number was 277523JC1B which when I looked it up said that was called a bracket air conditioner amplifier. The part number that Nissan gave me for the mode door was 27731-3SBOA, which looks totally different. But it has the same white square on it where it hooks onto the door lever, but it’s a lot smaller than the part I took out. Nissan will not take the part back. I spent hours looking for it and I removed some plastic ducts and there is nothing there, just that part called bracket amplifier. Which is about $500.00. I have manual climate control.

Below is a picture of the mode door actuator they gave me. Joe, the picture you gave me looks like the amplifier which is bigger and flatter the new part I got from the dealer, has the same white square part that will hook up the same way, but I don’t know about the mounting where it hooks up to the case that I never tried because it’s totally different.

Yes, that’s correct. I wanted to ask you if; I changed the air mix actuator and the air intake actuator the climate control is acting a little strange do the actuators need to be reprogrammed?

No, I didn’t disconnect battery, but now when I say I put the heat the fan speed is very low and if I shut the car off and just put the ignition on and don’t start car, then it works normal. Then start the car, it will work normally as soon as I change it to a different mode and back to the mode that the air is blowing on my face, it will go back to a low speed again. Then sometimes it will not switch to different modes. I then go up under dash on drivers' side and then touch the mode door linkage and then works normal.I didn’t have all these issues until I changed the actuators.

Hello Joe, thanks for getting back to me. You remember I was looking for the mode actuator. I went to a shop, and he looked it up and told me it’s on the top had to remove top of instrument panel remove the radio and bingo there was where the problem was. The linkage popped off because the mode actuator was bad. I opened it up and the plastic gear was missing a couple of teeth and had a lot of play. Installed a new actuator and good to go. Thank you for all your help.

Thank you, Joe, for all your help. You will be hearing more from me. I don’t have any Alldata or Mitchell because it really is not worth it for me to get it I’m really not that busy enough to get it.

Hi Joe, this is Tom. I have another question for you. My daughter has got a 2005 Jeep Grand Cherokee 4.7 it has a trouble code po452. My scanner says NVLD pressure switch stuck closed gas cap looks good. Could it be the vacuum leak detection pump on the charcoal canister be bad?
