I had to take the fuse out of fuse box to stop it from working.

When you say the air conditioner will not shut off, are you talking about the blower inside the vehicle?

The blower runs all the time. Check the fuses boat 17 and 23 nothing seemed to happen. When I put the fuses back in especially number 17 the air conditioning comes on with a blower and everything else is cold as it can be. Now I pull out number 23 used and I've replaced it, but when I did I don't have any light showing up on my mileage and all that jazz nothing shows up. I'm not having trouble with the car running or the lights on the outside or the tail lights or nothing.

None of my stuff shows up on my with my mileage or anything. Is it like that or how much how fast I'm going or nothing, but the signal lights do not show up but they actually work.

I looked at the diagrams of the things that you sent me but they were so blurred I could not read them not even with a magnifying glass.

I apologize, but I hadn't attached any pictures yet. Fuse 23 powers a portion of the Body Control Module, which would make sense as to why you lost indicators and other functionality with this fuse removed. It shouldn't have anything to do with your blower motor running all the time. Fuse 17 does power the HVAC (Heating Ventilation Air Conditioning) module and control panel, so this definitely would cause the blower to turn off(see attached diagram). Your vehicle also uses a blower motor control module(which is powered by Fuse 11) to control the speed of the fan. This is most likely the cause of your issue. However, let's see if we can narrow a few things down first. Can you verify that pulling Fuse 17 by itself causes the blower motor to turn off?

Yes, take 17 out and it stops, put 17 in it starts again. Can't switch to change.

I have a 6/12 volt circuit tester that I can check the fuses tomorrow. It's too cold to get out now.

When you have the fuse installed (and blower running) are you unable to turn the temperature control to heat? Does the mode switch (defrost/vent/floor) respond to changes?

None of the switches work. It like they are dead when you depress them. What about the Blend door actuator could it be bad?

At this point, it sounds like your HVAC control head has failed. Attached below are the replacement instructions.

Have ordered the HVAC control Head. Will receive November 13, 2019. Do I need anything else to order with that?
