I have a 2007 acura tl type s AT with 122000km, I know there are plenty of threads regarding this topic but i have a few questions that i could not find. Many people replace these as preventive maintenance items but what intverals or mileage have you guys replaced yours or recommend replacing them and have you noticed any difference. Also is there any warning signs that I should be looking out for that mean they need to be replaced. Any help or information would be very helpful

 

There's a master thread here: https://acurazine.com/forums/third-g...2008-a-840630/

 

I'm about to replace the switches on the '07 TL 3.2 I just purchased. 137k miles, original switches are still on there currently, so this will be the first time they're replaced. I will try and remember to check back in once the job is done.
