Climate Control Issue
Hello all,
I have a 2002 Acura TL-S with navi. Earlier today I turned my car on and the ac/air blew a constant speed and would not stop, even if I pressed the off button. I turned the car off and then turned it back on and it then worked properly. But now its back to blowing a constant speed again and fu*k*d.
I have been searching google and came up with a few suggestions of people saying its the actual climate control that has to be replaced. But the climate control "unit" would be the entire navigation in this case, correct?
Any opinions on what it maybe?

No, the navigation and the climate control buttons are separate consoles. The navi has some A/C input as well, but I don't believe it would affect the OFF button. If the problem appears every now and then, I would rule out a broken fuse or motor. Hmm, it might be expensive to replace the A/C console, so I would run a HVAC DTC test before replacing anything. Hopefully someone else can offer more experienced advice.

Tried the DTC test by holding the Off and Auto button. I got an intermittent flash between "88" and two underdashes " _ _ " I did not get any letters or numbers other than those... Hmmm....

K= A problem in the air mix control linkage, door, or motor.
N= A problem in the blower motor circuit.
It seems you have already figured out/fixed the "N" problem with the blower motor. Try getting the codes again, and see if anything flashes. If you still get the "K" code, then I can help you with that. It's an easy fix.

The "K" code is for the heater air mix control. Basically, as you increase the heat, the control motor slightly opens a door from the hot engine bay.
Does your heater work at all? Is there a difference between setting the climate control from a little hot to max hot? When you start the car, do you hear a noise coming from under the passenger side feet compartment?

^Video showing the control motor. If the motor is bad, you can repair it or replace it. It costs ~100 bucks new. There's also a chance that the control arm just got misaligned, and you just need to re install it.
If it is bad, I can show you how to repair it. Most likely, you were going at a high RPM drive, and the heat of the engine caused the motor to get really hot. When it cooled, the gears got really brittle and snapped. It's easy to repair. You just spin the gear around 180 degrees.

heater works no diffrence from max heat or regular heat i either push button on ac or leave off for heat....no ticking noise but my ac blows ice chunks then sometimes it dont recharged it and i think i have issues i either over filled cuz pressure on high side at idle is 300 while low side is normal operational psi car is highly modified headers high flow cat exhaust cai a bunch of stuff but like i said sometimes it blows ice chunks other times it dont compressor kicks on then off then on then off just like that and other times no issues but the code it gave me was the k code and now it wont spit a code out when i hold the buttons....so i dont know radiator is comin out tonite soon as i get off my ass,then a flush and a replacment radiator....dont know if this helps or not but thanks anyway

Yea, I understand now. Your heater air mix control is messed up. It's probably stuck, so that the A/C can only activate when the control can break free.
Observe the motor in that video to see if it's messed up. As you adjust the temperature, it should move little by little. If it doesn't, then it's broken.

Karanx7, I have a 2000 TL. Fan blew constantly but no AC. I ran the troubleshooting and got back codes I and N. Played with some of the connections and relays and now the AC works. My only code now is "N". Fan still blows constantly. Can you offer any ideas on this? I do not have the book above that says to check pages 21 - 31. I"ll send you my email address if you'd like. Thanks in advance

Karanx7. I have a 2002 Type S with the same issue as Oldsaintsfan. I did the troubleshooting and got codes K, I, and N. I read on previous posts about changing relays and resistors. Is there anywhere I can see how to replace these components or how to get to these components. You seem to be the go-to guy in this thread. Thanks.

diy section, cabin filter replacement
will take you to the blower motor and its resistor

If you're in the vicinity of the ac cabin filter and blower motor behind the glove box, then the resistor pack is slightly to the left. You'll want to look for a wiring harness and connector. There should be orange/black wires present to this transistor. My wiring actually started to melt and I had to replace the connector and wiring pigtail for the assembly.

CCU issue
I have done the on board diagnostic test and i am getting the N code, but my compressor kicks on for a few seconds and then kicks off. The disconnectors are plugged in correctly to the blower motor and everything worked yesterday?

Welcome TrahanAcurA99 !!!
The "N" code indicates a problem within the blower motor's circuit.
Check the #56(40A) fuse in the underhood fuse box. Also the #3(7.5A) fuse in the driver's kick panel fuse box.
There's a good chance that the blower motor's wiring harness connector is shorted.

Try directly jumpering power to the blower's motor bypassing it's circuit. Be careful !!!

Download a copy of your cars service manual, then you will be able to look up the code and solution for you. I found a free copy for mine but I do not remember what the site is. You can also buy it for $20.

I am not sure if I'm having the same problem, my climate control will intermittently lose power like the control light go off, so then my Acura TL '06 will go to full defrost mode (which I assume is a safety default for when you lose climate control). Does anyone have a idea of what might be causing this? The issue has been going on for years, it will be running fine then it will go out and it can be days before it fixes itself. I assume it might be a bad grounding wire to the climate controller, but I'm just guessing haven't diagnosed.
