air conditioning
« on: 28 March 2008, 10:10:05 »
how does the airconditioning actually work on my cdx. i presumed you just turn down climate control to low.  is this correct if so its not very cold, or does the condenser need re-gassing at all.

As long as "ECO" is not showing in the display, air con runs all the time climate is on.

First check is to see if the 3 lugs on the air con compressor pully are spinning when climate is on (also the 2 front cooling fans should be running at 1/2 speed).

If this isn't happening the refrigerant charge is probably low and the system needs vac'ing out, leak testing and refilling with refrigerant.

I know this is a bit old but came across it. My aircon is never very cold. I went to Quickfit who claim to top up aircon for £50. They tried but said that they couldnt because there must be a leak. Is there any way for me to determine where this leak is? Or if it is maybe another problem?

you could use a colouring dye in the a/c system (not that i know how you'd go about doing it)

the best way to find a leak is to find someone that can presure test the system with nitrogen as it will fill the system to anywere between 6-10 bar(not a diy job sorry)

and incase you think of giving the diy kits a go save your time and money these are a waste of time and get outlawed in april  ;)

Yep. Best to give the DIY kits and Kwik Fit a miss and go to someone who can diagnose and repair any problems. Normally a specialist will not charge much, if any, more.

Always use an ac specialist, they cost little more than the £50, and do the job properly. Its a specialist service requiring the correct equipment. So avoid the top up services, although quick fit up sound like they have been unusually honest in this case, as they are normally quite happy to blindly fill up without a leak check, only for the customer to find the ac stops working a up to a month or so later, depending on the leak.

 Unfortunately, in my experience, the gas in my old 99 cdx went for almost 6 years before the dreaded  --  symbol appeared in the climate display, which means an ac fault, the problem in my case was found to be a leak. £150 for new condenser AND drier (the drier being a must if the system has been opened to the atmosphere) from autovaux. So, the odds are, more likely to be a leak than a top up, lets hope for the later.

Off topic a little but without air con (ie in ECO mode), I find the car windows smetimes mist up really quickly and I need to give a quick blast of the air con to clear them, and then they'll mist up again in ECO.  Is the Omega prone to poor air circulation?

Depends if the boot storage compartment vents are clear or not and when the air con is on the dehumidifier is working  :y

To be honest I leave mine on auto all year round as switching it off only saves a thimble full of fuel ::)

Set the display to "instant fuel consumption", find a nice level stretch of road and with the car at a constant speed, turn on the A/C.  Mine drops by about 4mpg.

I read some where that the tech2 can reset the climate control. What exactly does it reset?
