Hi There,

On your first question you may just need a recharge. It is a good idea to periodically have the system evacuated (vacuum) and recharged including an oil charge. This is just

good preventive maintenance and will lengthen the life of your system. Most any auto shop can do that. As part of the process, they will likely use the pressure gauges to ensure there

are no leaks. That should resolve your problem and concern...Or at least determine if you do in fact have a leak.

Second, you should be able to find the A/C vents by searching eBay "996 vents" or "996 A/C" etc. They are on the site all the time with varying prices. You can also contact LA Dismantlers

as they have a huge Porsche salvage yard and a website at: LA Dismantlers

Good luck

The air conditioner is a closed system, unless you have a failure of a component, there is no need to flush the system. If you don’t have the gauges to check it yourself have a mechanic take a look at it. You don't need to take it to a dealer for A/C service. Once the tech puts gauges on the system he will be able to tell if it needs topped off or if there is a problem with the system. If the system has leaked down due to a leak he must by law repair the leak before he recharges the system. A number of things can cause this including o-ring failures or the front seal on the compressor. The o-rings get hard with age and repeated exposure to high temps and can slowly leak over time. Simply replacing them usually fixes the problem. Good luck.

There have been some cases of corrosion at the lower corners of the condensers. Trash, paper, leaves, cigarette butts, etc., get impacted between the condensers and the radiators and when wet set up a corrosive reaction that will eventually cause holes to develop in the condensers and/or radiators.

If you do have a loss of refrigerant, and a leak is indicated, check for pin holes in the condensers.

The folowing cleaning instructions were posted for early 986 Boxsters....but, they are pretty close for 996 Carreras.

I believe there may be similar instructions here on RennTech but am not well enough versed in the search function to be able to find them.

You can determine if the system is operating reasonably correctly by turning it to max cooling, recirculate, lowest blower speed, and verifying that the dash outflow air reaches <45F within 3-5 minutes.
