HI, Folks, first post. I'm a new owner of a db7 and live in the desert southwest USA. The summer temperatures get to 43* and higher. The A/C, while adequate for Scotland, I'm sure, is not OK here. I need more than a hint of cool air. More like a cold blast. Does anyone have any suggestions for aftermarket equipment that I can install to make summer driving reasonable? I will appreciate all replies (except snarky ones :-)

Have the system recharged, has probably lost pressure over the years

Thanks - has been recharged. I'm going to try a different refrigerant. I'm hoping there are some replacement fans that put out a lot more volume of air.

Wasting your time trying to fix it. It is based on the very antiquated Jaguar XJS HVAC system and is no better. You have to move to Aston's Gaydon platform to get 'modern' (i.e., adequate) A/C.

I had an XJS for almost 30 years and I live in Florida and it gets pretty hot here. If the AC system is working properly you should not have cooling problems. You need to get it checked by someone who knows what they are doing.

Even then, it's still not great.

True, but far better than the DB7/XJS antiquated system. Just not enough air volume from the top vents.

Well, I had 4 XJS's over a 20 year period, and they were all poor as compared to modern AC systems. The DB7 was a little better, but not by much...just not enough air out the top. You can fiddle all you want, but it'll never be great.

Agreed. Still gets too hot, even in the UK.

I drove my first V8V in Doha, Qatar for two and a half years where it's generally above 40C from about April/May until late October/November, getting up as high as 50C in the summer months. It was a nightmare at times, especially commuting along the corniche or going to meetings and trying to arrive in a reasonably presentable state.

The vents on the dash are too high up and don't point far enough down to hit your core if you have the seat low. As has been mentioned by a few others, there just isn't enough volume to cool even the small cabin of the Vantage enough. I was told when I bought the car that there was no difference in A/C spec between the UK cars and middle east cars and it certainly seemed like that was the case.

All that lovely metal and leather in the interior turns into a frying pan when it's been sitting in 40+ and you're wearing shorts or short sleeves. At times I had to wait for the steering wheel to cool down before I could drive away.

I'd still do it again though! :-)
