so i did this today...pretty easy only had 1 bolt in it...maybe its been done before.....pulled it apart and there is only 4-5 teeth left on the little cog...made it work put it together and its doesn't click now...which is great, but the vents still dont work, I have feet and i think half a windscreen the passenger side which is useless to me really......no dash vents at all.....the vent arm is moving with the motor and all but nothing changes...
