Leon / Toledo 99-04 Hazard warning lights / Indicators - DIY repair guide

Have your indicators started working irratically or intermitently? If so check the hazard warning light switch.

Does it cut out after a short period of time/ work irratically or just once?

Both problems will almost certainly be caused by the hazard warning light relay which is (un)conveniently located inside the hazard warning light switch. The part number is 1MO941509B costs around £32 to replace and looks like this -

THE GUIDE:

The following guide is the method which I used to swap and install a new one. Follow at your own risk - I accept no responsibility for any damage caused. If you follow this guide correctly and take care it will be a breeze.

THE TOOLS NEEDED:



- metal spatula/kitchen knife - must have a bit of flex in it
- T20 torx bit - essential that either use wrench and socket extension or torx screwdriver
- Seat sound system 'aura' removal tool or my improvised collar stiffeners - used the AA battery as scale they should be that long but not as wide as battery - if you have an old store card or credit card cut that up and use that
- long allen key this is a must or very similar tool will be used for 'hooking' the switch out only

1.The start (ideally!)


2. First of all pry out dummy button with knife/spatula taking care not damage surrounding areas.
3. Next put the stereo removal tool totally straight in both areas arrowed. once in correctly you should sense a click that you have released something. now gently jiggle unit from side to side and it should start to come out but do not remove it fully.


4. with the stereo half hanging out you should see two screws that need a T20 torx bit to be removed. to save losing them you can put all screws in the area next to gear stick




5. next with same torx bit remove the screw inside the flip down ashtray.


6. Once you have disconnected the ciggy lighter, remove the last two screws...


7. Now gently pull away the bottom half of panel first making sure the stereo unit is still half way out.

8. Now with great care, as there are little clips behind it, remove the top part of panel as shown


9. It should now look like this


10. This is the tricky bit take your time!! - insert the allen key so that it can hook out the rear windscreen heater switch- make sure you pay attention to the way the allen key facing. Make sure the stereo and panel are not pulled out completely! again take your time and use a gentle pull!


11. Once that has popped out the hazard relay switch will be exactly the same, carefully manouevre the allen key in the gap and pop it out in same fashion.


12. Now carefully separate the clip arrowed (that is on both sides) with the knife and swap part over!


job done! now test it and use opportunity to check that all blinkers are working! refit in exact of reversal making sure you reconnect the ciggy lighter!

Hey good guide! hope these will be of help to people

The part is only available from SEAT (part number 1MO941509B) or you can buy a VW one intended for mark IV Golfs/Boras however SEAT dealers probably won't tell you that!

I seriously doubt any auto parts supplier will sell one due to it being a specialist part.
If you are still stuck try getting it delivered from one of the dealers on here.

Be careful when removing it too. It's very easy to damage the surrounding areas when levering it out- as mentioned in the second guide.
