does anyone have a picture of the port?
I know what its supposed to look like, but I dont think I can find it..

there are 2 by the passenger side engine compartment in the back..
butthey dontlook like they come from the a/c compressor...

 

You don't, you check refrigerant PRESSURE. You need a high and low pressure gage to do that. In the good'ol olden days, there was a sight glass that you would look for air bubbles...but they did away with that to save 5 bucks

 

As Racer said, it would be best to have professional hi and low pressure
gauges but you can get by with a recharge kit form an Automotive store.
They have a built in pressure guage for the low pressure side and a
trigger. You connect it up with the AC on high and you will get a reading
on the low pressure side. The gauge is usually color coded to tell you
if the level is low. Not a pro set up by any means but works to
recharge your system. The hose and guage are reusable too.

Are you having a problem with your AC?

 

no.. no real problems
its just not as cold as id like it sometimes and I think the refrigerant level is low..

but let me rephrase

I bought a recharge kit with a guage..
where is the low pressure port so I can check and maybe refill....

i dont know which one is high and which is low..
if I am even looking at the right ports..

 

Yeah, it's dumb to keep adding refrigerant into a leaky system.

here is the high side gage port, I don't have apicture of the Low side.....Unless you know what you're doing, leave it to the experts..this system can be easily and costly damaged if over charged.

 

I dont think its leaking.
It gets cold just not super cold like it used to...
I've been using the a/c a lot lately.

I know what im doing tho..
I've done recharges on bmws before...
just not jaguars or any V shaped engines..

 

doesnt it get used up as I use the a/c?

 

Need more cold air? I leave in an aried side of the country where it really gets hot in summer as in very hot( the city that never sleeps, Las vegas) and I used my AC most of the time. I experienced the fluctuatuation in temperatureto warmer air. Try closing all the air vents on the passenger side if your alone driving and decrease the demand to lower temperature, set your ac on automatic, after a few minutes you feel the coolnes again.

If you have a leak, your will never get a cool air from your ac after awhile of driving. for it dissipitate very quickly. I have my xtype ac system checked from a proffessional ac mechanic in town but I was given the impression that most of the non-europeanAC specialist are hessitand to mess with it. Given that impression, I wouldnt mess around with it my self. Specially the AC system is so delicate that when its broken , It can cost an arm and a leg to get it fixed. recommend get a jaguar dealer diagnose it for you..

My 2 cents.............

 

O ok..
its not that big of an issue to take it to the dealer..
just a can of r134 worth.

so I guess I'll just leave it alone

 

no..this is a common misconception..It don't get weak, worn out, or used up..If the system is leak free..the Refrigerant is good forever.

 

i knew i spelled that wrong.
lol.

you know I think I just figured out what the problem might be.
the outside temperature is wrong sometimes...
It will sometimes say like 115 degrees when its really about 80.. so the sensor might be throwing things off...
anyone have any info on the exterior temperature sensor?

I mean it still gets cold...
but my friends cadillac cts gets freezing..
which bothers me..
lol

 

Check interior temp sensor inside cab, under drivers side knee panel. Over the years it can collect dust and what not, masking the true temp of the interior.

The interior temp sensor also has a mini fan blowing on it to circulate cabin air (that's how it knows what the cab temp is) check it and ensure fan is still working.

If the sensor checks out, check the A/C system pressure.
