heater blower in my 2008 Seat Altea 1.6 petrol

Hi, thanks for having me here!

I'm trying to fix the cabin heater blower in my 2008 Seat Altea 1.6 petrol and have already replaced the heater motor (which seems to have a built-in resistor) and checked the fuses, but the blower still isn't working. I'm now thinking it might be the relay.

I’ve found the relays near the fuse box under the steering wheel, but I’m unsure which one controls the cabin heater fan, as there are multiple relays and no diagrams available.

  1. Could you let me know which relay controls the cabin heater fan, or provide a diagram?
  2. Also, any advice on turning off the airbag light? I disconnected the passenger airbag while removing the glovebox—oops!
Thanks for your help! John
