Mazda 3 - Kølevirkningen aftager under kørslen | HELLA
MazdaMazda 3Fra årgang 2006Kølevirkningen aftager under kørslenI ovennævnte modeller kan kølevirkningen fra klimaanlægget aftage på langture (klimaanlæg på højeste trin). Årsagen kan være, at klimafordamperen rimer til.Et yderligere tegn på dette problem kan være, at lavtryksrørledningen er dækket af et lag is.Mulige fejlkilder kan være fordamperens temperatursensor samt en ujævn luftfordeling over fordamperen.Problemet kan afhjælpes ved at udskifte sensoren med en tilpasset sensort (med tilhørende modstand) samt udskiftning af kabinefiltret med forbedret luftfordeling.- BP8P-61-J6X Filtersæt med diffusionsplade- BPY-61545A Ledningsbundt med modstandBilfabrikanten anbefaler er foretage nedenstående tilpasning.Noter radiokodenAfmonter batteriets minuskabel, og vent mindst 5 minutterAfmonter sidepanelet i passagersidenAfmonter fordelerdåsen, og løsn metalbøjlenLøsn stikket til fordamperens temperatursensor, og fjern Power Mosfet (biler med automatisk klimaanlæg)Afmonter dækpladen over fordamperboksenTag nu klimaanlæggets øvre og nedre filter udSæt de nye filtre med diffusionsplade (fig. 1) på plads, og sørg for, at pilene på filtret peger bagud (fig. 2). Monter dækpladen over fordamperboksen igenForbind det korte ledningsbundt inklusive modstand med stikket. Forbind derpå begge dele med fordamperens temperatursensorMonter afslutningsvis de resterende afmonterede dele igen, og kontroller klimaanlæggets funktionFig. 1Fig. 2

Cooling capacity diminishes while driving
In the course of a longer journey made in one of the above-mentioned vehicles (with the air-conditioning running at full speed), it is possible that the cooling capacity of the air-conditioning system begins to diminish. A reason for this can be the freezing of the evaporator.
Another sign indicating this problem is the presence of a layer of ice forming on the low pressure line.
Possible causes of this trouble are faulty temperature sensors on the evaporator and also an uneven distribution of air flowing through the evaporator.
This problem can be solved by renewing a sensor that has to be correctly adjusted (including its resistance) and by replacing the interior filter to achieve improved air distribution.
- BP8P-61-J6X Filter set with diffusion plate
- BPY-61545A Wiring harness with resistance
In these cases the following adjustments are recommended by the vehicle manufacturer.
- Make a note of the radio code
- Disconnect the negative poles of the battery and wait at least 5 minutes
- Remove the side panel on the passenger side
- Remove the junction box and loosen the metal bracket
- Undo the plug of the temperature sensor on the evaporator and remove the power MOSFET transistor (when automatic air-conditioning is present)
- Remove the cover of the evaporator box
- Now take out the upper and lower filters of the air-conditioning system
- Insert the new filters with the diffusion plate (Fig. 1) and make sure that the arrows on the filter are pointing in the direction of the rear (Fig. 2). Replace the cover on the evaporator box
- Connect the short wiring harness including resistance with the plug. Then connect both with the temperature sensor on the evaporator
- Finally reassemble all the remaining parts that have been removed and run a check to test how the air-conditioning system now works
