1996 Audi A4 Air Conditioning Causes Fuse/FuseBox To Melt
I've taken my Audi to the dealership and spent a whole lot of money trying to get them to fix this issue. Right now, the air is not blowing cold, the fuse is melted on one side (30amps which I've since replaced but still doesn't blow cold). In the past the fuse has actually caused a large portion of the fuse box to melt, but the Audi dealership replaced that (though...it doesn't seemed they fixed the problem of what caused the melting in the first place). The fuse has now been replaced a total of 3 times in the last year.
Looking at the receipt, the dealership also replaced the freon, fixed the computer (though exact details unknown), replace some o-rings, some hose. (excuse the lack of details here, I'm having to translate the receipt which is in a different language...these repairs were done to my Audi in Bangkok at the dealership).
I've noticed that the air con display has always flickered on and off, enough so that on occasion you can hear the air con system actually shutting off and on again.
My first question is....Does anyone have any idea what is causing the fuse to melt?
Second question is...Any suggestions on how to get the air con blowing cold again and the fuse to keep from continually melting?
Desperately need the air con working as if you're familiar at all with the weather here in Thailand, the summers in Louisiana are no match for the heat and humidity here....can't drive 5 minutes without being covered in sweat. Anyways, thanks in advance.
Oh..I also get a clicking noise, once every 2-3 seconds and it sounds like it's coming from behind the fuse box....perhaps a relay?Oh..I also get a clicking noise, once every 2-3 seconds and it sounds like it's coming from behind the fuse box....perhaps a relay?

Facia one fuse 25
facia two relay 16
facia three fuse 5, relay 2, relay 3
all three of the above panels are located on the drivers side (which in the diagram i have is righthand drive).
Those are pretty much all the fuses and relays that control your a/c. the clicking noise you hear is probably one of the three relays i've listed. now i don't know alot about audi's except i'll never own one. but i have a lot of information if you have other questions.
that flickering you noticed could be one of the relays failing or you have a short somewhere in the wiring.
anything else you need feel free to ask

Please take a moment to rate this solution .. thanks
Incidentally the only reason that i can think of that those parts would melt is that the current is high on those wires. are there any recalls that you are aware of ?

I think it's coincidental; I think the air conditioning fuse or circuit breaker has blown. Check the fusebox - this fuse should be labeled "AC" or "A/C".
You need special adapter , available from dealer only.
Low pressure switch has to be taken out and adapter installed insted.
I also heard rumor that you can charge system through high side at 3000 rpm , but never tried it , sience I have an adapter.
DID YOU PHONE THE DEALERSHIP BECAUSE THE PEOPLE ON THE PHONELINES ARE USELESS PARTIME WORKERS I THINK, ORDERING WRONG PARTS, SAYING PARTS ARE IN STOCK AND THERE NOT ETC ETC ETC.CUSTOMER SERVICE STINKS. I WOULD CONTACT LAST OWNER, ADDRESS WILL BE ON YOUR LOG BOOK V5,OR TAKE THE CAR INTO A OTHER DEALERSHIP AND SPEAK TO SOMEONE WHO HAS SOME MECHANICAL BACK GROUND....CHECK FOR A BLOWN FUSE,FUSEBOX IS ON THE DRIVERSIDE SIDE PANEL PRISE OFF WITH SMALL FLAT SCREWDRIVER.HOPE THIS WILL BE OF SOME HELP TO YOU......LOOK AT OTHER CARS LIKE YOURS IN THE DEALERSHIP FORECOURT AND SEE IF THEY HAVE STEERING WHEEL STEREO CONTROLS.(MAYBE AN UPGRADE OPTION FOR YOUR CAR) GOOD LUCK...NICE CAR...
Open the driver's door and look at the side of the dashboard. You'll see a funky-shaped panel on there. It has a finger-pull cutout in it. That's the fusebox cover. Pull it off and you'll see your fuses.
NO FUSES ON MY AUDI A4 2002 FOR HEADLIGHTS ETC. LOOKED UP MY HAYNES WORKSHOP MANUAL (WIRING DIAGRAMS) WORKS WITH THE POWER SUPPLY CONTROL UNIT, THERE IS ONLY ONE FUSE ON THE DIAGRAM FOR HEADLIGHTS ,SIDE, TAIL AND THATS FOR THE WHOLE ELECTRICAL SYSTEM 150AMPS RIGHT NEXT TO BATTERY.............. HOPE I HAVE BEEN OF SOME HELP TO YOU..
take down the lower drivers dash and look up to the left of the brake pedal. there you will find the main fuses that power the entire fuse panel as well as the rest of the car.. the large fuses there may have been blown.
Oh..I also get a clicking noise, once every 2-3 seconds and it sounds like it's coming from behind the fuse box....perhaps a relay?
