Dion Report post Posted July 22, 2015 What is wrong with your existing AC? Not nearly effective enough. I don't think there is anything wrong with it, it's just a crap system that needs modernising Quote Share this post Link to post Share on other sites More sharing options...
IlToro Report post Posted July 22, 2015 I shudder to think. I have been reviving the AC on my 40 year old Pantera and have discovered an AC system is it's own entity. Pretty complex with lot's of things that can be a problem. "Experts" aren't necessarily the answer either. Quote Share this post Link to post Share on other sites More sharing options...
SYNYSTR Report post Posted July 22, 2015 There were 2 things that were baffling to me in my 91 D. First, it sounded like the blower motor should have been pushing more air out the vents. I could hear a small tornado in there when the fan speed was on high, but not much air volume coming out. I never did figure out why. Second, the condenser behind the driver's side radiator (or in front of depending how you look at it) was way too small. Most cars have a condenser twice as large. The only way I figured I could compensate for it would be to improve the volume of the radiator fan. Maybe a more powerful fan or a second one to help out. That would run in to additional problems though. The wiring that fed the original fan seemed too thin and the alternator is a little too weak to begin with to add another 20 amp load. At the end of the day, I just lived with it. Quote Share this post Link to post Share on other sites More sharing options...
Chipster Report post Posted July 22, 2015 Mine isnt even connected lol. When I first got the car, I remembered people saying it robbed power so I disconnected it. And I was ued to the AC never working on my old Viper anyways. Plus I like driving with the windows down. Quote Share this post Link to post Share on other sites More sharing options...
falconsprint Report post Posted July 22, 2015 Plus I like driving with the windows down. The OP has a SE30, so rolling down the windows isn't an option! Quote Share this post Link to post Share on other sites More sharing options...
Dion Report post Posted July 23, 2015 I've emailed a pal who has restores classic cars and he has retro-fitted AC systems to them, so will let you know his thoughts. Quote Share this post Link to post Share on other sites More sharing options...
Chipster Report post Posted July 23, 2015 I've emailed a pal who has restores classic cars and he has retro-fitted AC systems to them, so will let you know his thoughts. Please do. And good note about the Se30 windows. That would be brutal Quote Share this post Link to post Share on other sites More sharing options...
Dion Report post Posted July 23, 2015 His response below "Efficiency is possibly a result of leakages in system . From my experience even if system is pressure tested it will only last a few weeks as leaks in unseen areas are hard to detect. Depending on refrigerant currently in system (R12 banned), requires conversion of almost entire system to high barrier hoses & receiver dryer to use current R134a. There is however a new gas which does not require conversion. We always sub-contract these services and will locate some mobile contacts" Quote Share this post Link to post Share on other sites More sharing options...

Benny Report post Posted July 29, 2015 Something to consider, mine is nice and cold on a hot (100 degree) night obviously when there is no sun. But when the sun is shinning it struggles (no tint). Tells me, one easy possible fix would be CERAMIC tint. I have heard many good things about it keeping 70% of the heat out. Since the windshield is huge and the side windows are curved allowing a lot of heat in the cabin. It has to be ceramic film though and the windshield would need to be done to be efficient.

Davo456 Report post Posted July 30, 2015 Many thanks, I'll drop him a email for some pointers Hi Dion, Check out the coolant valve - if it fails, you get warm engine water in the heating system, which defeats the AC. For a RHD car, its in the door sill (rather than under the dash as in a LHD car), see here.. http://www.lambopower.com/forum/index.php?...=99+SV+rebuild# Quote Share this post Link to post Share on other sites More sharing options...

BigBadLambo Report post Posted August 31, 2015 I just upgraded the AC on my G. It wasn't working worth a damn and I found out it only had 49 (grams?? or whatever) and it was supposed to have 550. So it was SUPER low. Check your Freon levels. They said it showed now leaks but when it was done it was blowing out 39 degrees.

They said it showed now leaks but when it was done it was blowing out 39 degrees. any more than 10% loss of refrigerant will make the system not cool, so if you had 500g left, their would be no cooling. 49g left tells me there has been a significant leak my dear friend.
