#65 of 73 Poor AC operation fix by targettuning Sep 25, 2007 (9:08 am)
I cannot totally confirm the authenticity of the following information but Honda of America has supposedly issued a service bulletin addressing the poor AC operation on all 2006 and some 2007 Civics. Issued: 19 Sept 2007 Service bulletin #: 07-062 Affected vehicles: all automatic 2006 sedans (and maybe..probably...coupes as well) And a serial numbered list of 2007 models THE FIX: a reflash of the PGM  I will post further info as found.

Replying to: targettuning (Sep 25, 2007 9:08 am) You are correct. I JUST got a call back from the Honda dealer. I had this patch uploaded about a month ago before the bulletin came out officially. When this one came out officially , I was at the dealer with a Honda rep trying to figure out what to do next. We thought it was a newer update but it wasn't (according to the call today). Still did not take care of my problem so I am not sure what my next options are.   12K miles on the car. Thank You
#67 of 73 Mobile, Alabama A/c results in 2007 Civic EX Coupe by ts45 Sep 30, 2007 (3:35 pm)
1st full summer season in Mobile Alabama, our temps average about 95 + from mid July to mid Sept. The Civic EX 1.8 Liter AC system worked fine, once cooled down maintained Cabin temps to whatever was needed.   Any Honda I've owned has taken a little while to cool down.
#68 of 73 Location of air conditioning relay for a 2000 a Honda Civic Lx by xlstealth Dec 18, 2007 (4:38 pm)
I lost the book for my 2000 Honda Civic Lx and cannot find the location for the air conditioning relay. My honda air conditioning and heater fans have stopped working the lights that usually come on are no longer working. We tested the fuses which appear to be okay. Auto Zone suggested that it must be the relay switch. Does anyone out there know where the switch is located on the Honda Civic Lx 2000.

#70 of 73 Deactivating A/C by will26 Mar 04, 2008 (9:10 am)
I was just reading on another website how people are putting in a code to deactivate the A/C when you use defrost. Using the code will give the person the option of turning the a/c button off. Would it be a good idea to use the code? I like the idea of it not running it all winter and think it might have something to do with my gas milage drop all winter but I'm just afraid putting in some code might mess with other things. Any ideas.. Replies to this message: shipo (Mar 04, 2008 10:13 am) tysalpha (Mar 26, 2008 5:17 pm) kenlw (Sep 26, 2008 10:17 am)

Replying to: will26 (Mar 04, 2008 9:10 am) One if the pitfalls of not running your A/C all winter is that the hoses and seals can dry out and/or corrosion can form on critical internal components. The refrigerant in your A/C system includes a lubricant and conditioner, and the circulation of the system (which sends the refrigerant through a dryer if I'm not mistaken) on a regular basis is key to keeping the system trouble free for many years. FWIW, most A/C systems deactivate when defrost mode is selected once the temperatures get down beyond a certain threshold (sorry, I don't know the specifics of the Civic system).   Best Regards, Shipo Replies to this message: tysalpha (Mar 26, 2008 5:17 pm) kenlw (Sep 26, 2008 10:17 am)

Replying to: shipo (Mar 04, 2008 10:13 am) Agree about running the A/C in winter. In fact, I would recommend using the A/C at least once a week, provided it's above about 40F outside. I've had no worries with my 07 Civic so far, but in my previous car I forgot this routine one winter (when the car was about 4 years old), and the A/C was completely ruined afterwards.

Replying to: tysalpha (Mar 26, 2008 5:17 pm) If your AC was "ruined" after one winter of not using the AC, i think your problems were elsewhere. Once enough freon leaks out, the low pressure switch will prevent the compressor from even coming on, preventing any subsequent damage to the system.   Worst case may be that the pressure in the system was so low as to allow moisture to enter and "soak" the dryer. In that case replacing the dryer would be the extent of the damage once the actual leak was located and repaired.   4 years of use (imho) indicates shaft seal wear on the compressor, the most common leak point on modern auto AC units after a few years. r134a is more prone to leaks anyway due to the smaller molecules .
