Evora a/c still not working

My a/c has never really worked for more than a few days since I bought the car.

It originally showed up as an error code which we've cleared several times. The fix only lasts a few days. Today we replaced the a/c unit under warranty. I noticed its very loud when running and the cool air lasted only for a few minutes.

So, asides from the compressor, what else could it be?

Haven't had that happen in the Evora, but similar problems in another car turned out to be due to a faulty temperature sensor in the system that prevented the compressor from cycling properly.

I had this too (long time ago). The reason was: loosing cooling gas out of the AC system due to puncture from stones coming in throu the front and damaging the cooling part. So the gas went out of the system and no more cool air came into the car. They replaced the front grid (to avoid stones to hit the inside of the car) and repalced also the radiator. Then it was ok.
Noise: Mine was never loud. A.

Thanks. I'll mention these possibilities. Also, I noticed a lot of suction from the lower air dam and venting from the radiators. I figure this is normal but it's really sucking....literally.

not sure if it is up the same alley, but my car is getting warranty work right this second-one of the things they fixed was a pinhole leak in the AC system (I need to find out where exactly when I go in) that caused a very sudden loss of AC ability (used to be great) though was prefaced by an electrical fault symbol on the dash for about a week 3 weeks before the AC gave out

Evora a/c still not working

I had the same issue. Ended up being the a/c clutch.

That's interesting, mine just gave out. Everything lights up, but I can't hear the AC compressor kick in. CHecked all fuses, so nothing basic like that. It's going in on Tuesday. I'll post back with any results.

They installed a new, tighter mesh up front? I'd like to do the same. The size of the stock mesh has always seemed too large to me.

Easy. Just take the grid of the Lotus Seven and attach it from the backside to the original grid. Works perfect. They asked me to check the temperature (possibly going too high due to lesser airincoming) but it is ok; I never had any temperature problems. So this is a cheap method to solve the problem.

Correct me if I am wrong but isn't getting at the backside of the original grid a pain in the rectum?
