Welcome to TN! Since the search feature here is iffy following the change, I'm gonna send you to Tacoma World. Go there https://www.tacomaworld.com/forums/2nd-gen-tacomas-2005-2015.5/ and enter "intermittent wiper switch" in the search window. You'll get a bunch of threads (at least one refers you back here to a TN thread) with part numbers and other info that should help you.

 

Welcome Linda Linda to the ToyotaNation. ?‍♂ I have not got a complete answer to your question. But as to "why" a dealership won't usually install aftermarket-even Toyota- parts is that the guys and gals in the service department have to work on cars for the type of job (i.e. fixing an engine fault light, changing the fan belt, etc. etc.) and they have a "rate book" that tells them how long they have to do a particular job. Installing completely new parts such as you describe is not in "the book" , also there is no accurate way they can know how much time and any extra parts they may need to customize your truck and still maintain the factory warranties. This is why specialty shops exist ( for lift kits, new wheels/tires etc.) At least all of this is what I've been told by dealerships I've dealt with over the years. However there is a bunch of knowledgeable people on this site and they likely will have a better answer for you, or even how you could do this your self.

 

Easier way is to go to the sticky up top, go to DIY post, then Ctl F search for wiper.

Should bring you here.

OEM Intermittent Wipers DIY

So, I decided to start a new post as so people could find this easy. I have also Pre-Launched www.toyota-diy.com/faq and I am slowly updating the DIY's on it so you can find this there along with a others that I have updated. This particular DIY can be found here...

Since the new format I never noticed the itty bitty magnifying glass up there. Now thanks for "finding" it for me

 

The link Splicer gave will point you to the part number. I replaced the wiper control on mine. It was a simple task. If you have a bit of a mechanical inclination, you can do the job. I found a used controller for mine and saved a few bux.

 

Don't use that one. It searches the Entire TN site. Worthless for most things

Top right, right of your avatar is three dots, last choice on the pull down is Advanced search. Set it to Tacoma and save yourself lots of pain.

 

Thanks RTFM, Gotcha- Oh boy more answers to questions I didn't even know I wanted to ask?
