SEAT Workshop Service and Repair Manuals

Removing –  Empty the refrigerant circuit → Air conditioning - with refrigerant R134a SEAT. –  Remove battery → Electrical system; Rep. Gr.27.   Note! t  Before disconnecting the battery, consult the anti-theft code of the radio. t  For vehicles fitted with electrically adjustable seats, remove them before disconnecting the battery → Bodywork, interior fitting work; Rep. Gr.72. t  On removal, note down bolt lengths and assignment for re-installation. t  All cable ties and other wiring harness fasteners released or cut open on removing air conditioner unit are to be re-attached in same position on installation. –  Remove the elements necessary to gain access to the connections of the heat radiator.

–  Mark positions of refrigerant hoses -A- and -B-. –  Pinch off both coolant tubes to heating system heat exchanger (e.g. using the clamp -U-30042-) and detach tubes. –  Disconnect the air release tube (from the upper junction -A- to the coolant expansion tank).   Note! t  Connect coolant hoses by the correct sides: t  Coolant hose -A-, supplied from cylinder head. t  Coolant hose -B-, return to water pump. t  Bleed the coolant circuit of air → Engine, mechanics; Rep. Gr.19.

–  Connect a piece of hose -A- to the upper junction. –  Keep a suitable recipient -B- under the lower connection -C-. –  Use a compressed air pistol to carefully blow the liquid coolant from the heat exchanger (into the recipient -B-). –  Remove the refrigerant tubes from the expansion valve → Chapter and secure them, for example with cable ties, so that they do not interfere in the fitting work.   Note! t  Seal open pipe connections. t  To close the open connections on the expansion valve or the evaporator it may be appropriate, for example the seal hood of an spare expansion valve or spare evaporator. –  Remove the passenger and driver seats → Bodywork, interior fitting work; Rep. Gr.72. –  Remove the glove compartment, the lower trim on the driver's side, the centre console and the instrument panel → Bodywork, interior fitting work; Rep. Gr.70.   Note! So as not to damage instrument panel outside lining, the control panel is only to be placed on a clean workbench covered, for example, with clean cardboard. –  Remove the accelerator pedal module → Fuel supply system; Rep. Gr.20. –  Fold the mat on the driver side and passenger side back so that it is possible to remove the vents for the foot well → Bodywork, interior fitting work; Rep. Gr.70. –  Remove the two vents from the foot well for the rear area. –  Remove the -V2- → Chapter. –  Remove the instrument panel and the crossbeam for the instrument panel (centre tube) → Bodywork, interior fitting work; Rep. Gr.70.

–  Remove the Data bus diagnostic interface (01299) -J533- (in the area of the steering column secured to the bracket -A-) → Electric installation; Rep. Gr.90. –  Remove the bolts -B- and release the support -A- for the air conditioning (the support remains attached to the cable harness of the vehicle).

–  Remove the two bolts -A- in the cable harness support -B- –  Unplug connector -C-. –  Remove the flexible condensation drainage tube → Chapter. –  Release the attachment of vehicle wiring harness (with cable ties) from the air conditioning. –  For those vehicles with an additional electric heating (only for diesel powered vehicles), release the cable connections to the voltage supply of the Additional heating element (00402) -Z35- → Chapter. –  Unplug all electric connectors between vehicle wiring harness and electrical components at air conditioner unit.   Note! The “air conditioning” wiring harness is removed with the air conditioning.

–  Pull out the air conditioning a little bit from the right hand side (until the bolt -B- in the right hand side support -A- may be unscrewed).   Note!

t  Pull gently on the air conditioning so that the support -A- does not break. t  To unscrew the bolt -B- insert a hand between the air conditioning and the floor mat in the right hand side wheel housing (this is possible if the fresh air turbine has first been removed). –  Remove the bolts -B- and release the support -A- for the air conditioning (the support remains attached to the cable harness of the vehicle).

–  Release the two brackets for the refrigerant hoses to the heat exchanger -A- and the expansion valve (to the evaporator) -B- in the openings of the grommet -C-.   Note! t  On removing the air conditioning, pay attention to both coolant pipes to heat exchanger to ensure that they do not catch on the opening to the plenum chamber or on the sound proofing mat and are bent or damaged. t  Pay attention to wiring harness. Pulling too firmly could damage individual wires.

–  Take out air conditioner unit -A- towards passenger side.
