>>Any idea how to take apart the Headlight stalk switch to clean the contacts?<< After destroying a Camry headlight switch, I see that there is a little cap on the end of the stalk that can be removed. Inside it is one complicated switch! I will probably squirt good quality contact cleaner in my switch and turn it vigorously for five minutes. Good thing I have a battery cut-off switch too.
yeah... take the complete stalk off and replace with a junkyard one....you will need to pull the steering wheel as well....but its an easy replacement tho.
