Hej. Jeg har en alfa 164 3,0 V6 fra ´91. Airconen køler ikke ordentligt, og jeg tror det er fordi beholderen skal påfyldes.
Er der nogen, som kan fortælle mig hvor beholderen sidder, og hvordan den skal påfyldes og med hvad? Hvordan gør man?
Hilsen Jonas
Påfyldning af aircon
Oppe i topedorummet, der hvor blæser og alt det andet klima regulering sidder. der er der et lille skueglas hvor der skal være vædske i når klimaen køre, man kan på min høre et klik når koblingen til kompressoren trækkes, og derefter mærke på slangen derfra at den bliver kold. der sidder en termostat under et lille plast dæksel, som styre temperaturen (målt efter køle elementet) som bestemmer ved hvilken temperatur kompressoren slås fra. Denne kan justeres med en skruetrækker, men kan justeres til for koldt, så der kommer is ud af instrument brættet. Men selvfølgelig skal der være vædske i systemet før det virker. der findes foresten en måde på at teste Klima styringen ved med tændingen slået til derefter samtidig at trykke auto kanppen sammne med den fjerde knap til højre derfor, derefter slip auto knappen først og derefter den fjerde knap. Et internt test program køre nu i styringen i løbet af ca 20 sec. nu skulle der så vises nogle koder i displayet, og hvis flere fejl trykkes den fjerde knap for at vise den næste. På http://www.digest.net/alfa/FAQ/164/notes_80.htm kan du på side 16 finde fremgangsmåden og listen med fejlkoder.

Altså side 16 er hvis du printer den ud, men her er beskrivelsen og koderne
SELF-TEST CIRCUIT - GENERAL INFORMATION
The self-test program is activated, with ignition key to position "run", by
simultaneous pressing of button AUTO and 4th button to its right, then
releasing AUTO first and the 4th button successively.
The self-test program starts showing all of the lights flashing for 20
seconds and then if malfunctions are detected, the display will show their
quantity.
At this point, press the 4th button for the times corresponding to
malfunctions number. Each time the button is pressed, the display shows a
code that identifies the type of malfunction and the affected component.
The code is composed of two digits; the first number identifies the component
while the second letter identifies the malfunction type. After the
self-test, press the 4th button again to proceed with the system operation.

CODE MALFUNCTION
1U Open circuit on cabin air temperature sensor.
1C Cabin air temperature sensor shorted to ground.
2U Open circuit on external air temperature sensor.
2C External air sensor shorted to ground.
3U Open circuit on mixed air temperature sensor.
3C Mixed air sensor shorted to ground.
5U Open circuit on air mixing door motor.
5C Air mixing door shorted to ground.
6U Open circuit on air distribution door motor.
6C Air distribution door shorted to ground.
7U Condition of open circuit on recirculation door motor.
7C Recirculation door motor shorted to ground.
8U Open or short circuit between speed regulator and electric fan.
8C Faulty speed regulator.
Short between speed regulator and control unit.
EU Faulty control unit. Replace control unit Q21A
Please note; we've found a multi wire connector under the plastic cover just
forward of the windshield to become dirty and loose which effectively shuts
off the control panel. A very good candidate for Stabilant 22. Separate the
connector and treat with the magic fluid, or just clean as best you can and
tighten. I hope this Info will help you fix any problem with the A/C
control unit.
