Thought about that but indi I've been using says he's not sure what else may be fed through the same circuit.Pull the fuse?
Manual agrees with you thanks. Not had the cover off before under the steering wheel. It feels on pretty solid and tight. Not sure how I should pull it off so I'll give it a miss for now.If only there was some way of finding out what circuits are fed by that fuse. It's a conundrum wrapped in an enigma and no mistake
I wonder if it could be F52, 15A, under the steering wheel, top row, second from left.....
Mine do exactly the same. I just turn the heater switch and it goes away until next time. I would be interested in any solution too
Hello helpful people. My seat heater comes on randomly on my 2012 GTS. Apart from an unwanted hot backside, should I be overly concerned? Is there a simple fix? Thanks.
I took mine apart and squirted with electrical cleaner now works perfectly. Be careful iof the plastic tabs on the cover plate as they have a tendency to snap off
Pull the switch. Ive not done a GT one but they usually have two tabs on the shoulders of the switch that your press in so you can access the circuit board.
thanks for detailed explanation. Actually since I first posted problem it hasn’t happened again. At the time I think I did work the adjuster a few times and it would appear to have done the trick.Pull the switch. Ive not done a GT one but they usually have two tabs on the shoulders of the switch that your press in so you can access the circuit board.
Alfa ones are on the top shoulders. If you look at the attached link for a qp switch you can see the tabs on the bottom shoulders.
Take the circuit board out the thumb wheel comes out with it. Then you will have a circuit board that looks something like this.

Clean up the 4 arcs and the spaces between the arcs with contact cleaner and a cotton bud or suitable cloth. Also clean up the contact on the wheel or it may have detached from the locking position on the wheel. They are usually held in place by a small plastic pin you can glue it back in place if needed.
You have to drop the thumb wheel back into the hole at the top of the circuit board at the right point and then slide the whole circuit board back in to the switch cover until the tabs lock.
If the tabs break a spot of glue will be fine to lock it back together.
