This is how I fixed my Logitech G29 steering wheel whose left paddle shifter was intermittently unresponsive. If I pulled the paddle say 10 times, it would register the click about 3 times. Not good when it’s the downshift in a racing game.
I’ll cut right to it…
Take the wheel off the spindle to access the micro switches. There are loads of step by step videos on Youtube. It’s just 6 screws from behind the wheel, then the circle of bolts on the front around the logo. Oh, and unclip the short ribbon cable connection the wheel to the hub.
Mine seemed to be stuck in the bottom right of the red rotator switch (as you look at the wheel) but it was just a small clip inside that unclipped when I took a brave pill and pulled it harder.
Once you’ve got access to the micro switches that the paddles click, spray contact cleaner into the switch. I used the gap around the ‘clicky’ bit that sticks out under the metal spring lever.
Gently bend the metal spring out away from the plastic switch body so it needs a bit more force to click. Not sure this is 100% necessary but it makes it feel a bit better when used.
Put it all back together. Job done.
That fixed it for me, but obviously your mileage may vary.
