Introduction: Seat Ibiza Front Seat Heater Element Exchange

Picture of Seat Ibiza Front Seat Heater Element Exchange

The car front seats can be heated electrically during winter time. This is really great.
What's not so great is that once in a while will these elements break.
The question is when,not if. The probability increases with the cars mileage.

Anyway I own  a Seat Ibiza car, it is very close to the Volkswagen Polo and the Skoda Fabia. The seats are probably very similar over the whole VAG line.

My car is from 1998.


Step 1: Tools Required

Picture of Tools Required

You will need the following tools
Socket set (Not really, but there are some nuts and bolts)
Torx Screw driver (bits)
Allen Key
Thread Lock

AMP Connector disassembly tool
I did not know that this tool was needed when I started this project.
After some thought I decided to sacrifice my 0.9mm feeler blade. The feeler blade was grinded down to fit into the inserts for the disassembly tool. Note that two pieces are needed.


Step 2: Remove Front Seat From Car

This is described in the Haynes manual

1. Remove the head rest
2. Thrust the seat fully forward
3. Remove the plastic rail guard, it is quite easy to unclip it.
4. Thrust the seat backward
5. Just below the front seat is a stop screw/nut
6. Remove the stop screw
7. Thrust the chair further back and it will come loose
8. Unclip the heater cable that comes up through the floor.
9. Lift the seat out of the car

Step 3: Disconnect Back Heater Element

1. Lock at the connecter, the contact elements are numbered
2. Write down the cable colors and connector pin numbers for the back heater element
3. Insert your two pieces or the connector removal tool into the connector house.
4. With some persuasion will the contact element leave the connector house


Step 4: Remove Side Panels and Screws

My car does not have any back doors. You fold the front seats to get into the back seat.
The back locking bolt has a plastic piece that is locked with a Torx screw. Remove the screw and the plastic cylinder




Step 5: Remove Seat Belt Lock

The seat belt lock is fixed with one huge bolt and thread locking compound.
Take a fixed spanner and use some force

Step 6: Remove Back Plastic Gables

The Plastic gables protect the seat folding mechanism.

The gables are locked by some plastic pins.
The pins lock like small circles in the plastic. There are three lock pins in each gable.

Push the pins into the seat with a screwdriver.

The gable comes off quite easy when the lock pins are removed.

The back angle adjuster rod makes it more difficult to remove the gable. I left it on the back, but I rotated it around the rod

Step 7: Remove Back

Remove the two spring loaded washers on the shaft from the back.
It is now possible to separate the seat and the back

Step 8: Remove the Seat Tray

The seat tray is only fixed with one philips screw
Remove the screw and the tray comes off.

Step 9: Loosen Steel Wire Holding Chair Upholstery

The chair upholstery is primary fixated by a steel wire.
The steel wire is fixed by the plastic cylinders removed in step 3. The steel wire is easily pulled of

Step 10: Remove the Upholstery

The upholstery is fixed to the seat frame with something close to a clothes button. The steel wire can be lifted over the buttons at the structure on the front of the seat.

I used a screwdriver to remove the upholstery from the back of the seat structure. There are some sharp metal parts that cut into the plastic "hem", or plastic edge sewn to the upholstery.

The seat padding is now free from the structure, but the upholstery is still fixed to the padding.
There are three steel wires holding the upholstery to the padding, these wires come loose by compressing the padding.

Step 11: Reassembly

Start with the padding
Place the new heating element on the padding, but do keep the glue protection paper.
Replace the upholstery steel wires

Step 12: Fixate the Heater Element to the Padding

With the steel wires fixated in the padding, can the heater element be fixated to the padding.

Remove the protection papers.

Step 13: Final Reassembly

The rest of the assembly is the disassembly backwards.

Remember to use thread fixation compound when replacing the seat belt lock.

Hi, I have added a picture of the old heater element that I removed. The seat is back in the car, otherwhise it would have been great as an introductory picture. I will remember that next time

I remember Seats when they were essentially Fiat's under licence, but without looking I'm not sure what the Marbella was - Panda?
