Leon Mk2
| Removable electric components of air conditioning: removing and fitting |
| 1 - | Air conditioning wiring harness |
| q | Different versions (for example, with or without connection to the Additional heating control unit -J604-) → Parts catalogue |
| q | See → Current flow diagrams, Electrical fault finding and Fitting locations |
| q | Mark connections before removing them (the connections for the different servo motors and thermo sensors are identical, danger of confusion). |
| q | Fit the cable harness into the fastening points on the housing (using cable ties, or in the allotments so that it does not come into contact with any moving parts) |
Note| t | During model year 2006 the thermosensor - fresh air intake channel -G89- was gradually phased out; vehicles without this can only have control and indication panels,Climatronic control unit -J255-, with the part number from index “M”. |
| t | If vehicles without thermosensor - fresh air intake channel -G89- have a control and indicator panel, Climatronic control unit -J255-, with the part number up to index “L”, an entry is made in the fault memory. |
| t | Until the end of model year 2007, the dynamic pressure flap (fresh air flap) was operated by the dynamic pressure flap servomotor -V71-. At the end of model year 2007 the servomotor for dynamic pressure flap -V71- will be gradually phased out; in vehicles without servomotor -V71-, the dynamic pressure flap (fresh air flap) is operated through a cam disk and a lever by the servomotor for the air recirculation flap -V113-. For this reason, note the correct assignation of the control and indication unit, Climatronic control unit -J255-; if the assignation or adaptation are not correct, this situation is detected in the basic adjustment and registered as a fault → Parts catalogue |
| 2 - | Climate control |
| q | Different versions of Climate control in vehicles with manual and automatic climate control → Parts catalogue |

| 3 - | Additional heating element -Z35- with Additional air heating control unit -J604- |
| q | Only intended for vehicles with diesel engine, see → Current flow diagrams, Electrical fault finding and Fitting locations |
| q | There are different versions of additional air heating: Vehicles equipped with Diesel engines prior to November 2006 (gradual conversion) activate the heating element for additional heating -Z35- by means of the additional air heating control unit -J604-. Vehicles with Diesel engines produced after November 2006 (gradual conversion), carry a heating element for additional heating -Z35- with three phases; this element is activated by the corresponding engine control unit via relays and → Current flow diagrams, Electrical fault finding and Fitting locations |
| q | Vehicles with a Diesel engine and the extra equipment for “independent heating” also now carry a heating element for additional heating -Z35- In the future (introduction pending) these vehicles will not carry the heating element for additional heating -Z35-(the“independent heating” will run the operation of the “additional heating”) → independent heating; Rep. Gr.01 |
| q | Check the operation of the control unit for the additional air heating -J604-, carry out self-diagnosis. |

| q | Removing and fitting (see removal of the Servomotor for the air recirculation flap -V113-) → Chapter |
| q | Following fitting, test both servomotors to see if the bracket holds its position; if there is some play then eliminate it by applying some spongy material to the interior of the attachment points of the bracket → Chapter |
