Intermittent wipers stopped working

Anyone know why this would happen. When I put it on Int. they stay on like regular wipers. I have a 2013 Tacoma base. Thanks Randy.

 

Since the wipers work, and only the intermittent portion is malfunctioning, I would say the switch is bad. You can get a new one from eBay for $30 and replace it your self in under 10 minutes.
Tacomaholic has a video on YouTube that shows step by step.
I replaced mine yesterday, it is simple.

 

Thanks I will look at that.

 

Is this the stock wiper stalk that came with your truck? The Int setting on base model Tacomas it wipe / about 2 second delay / wipe ...
If you want truly adjustable intermittent wiper control you will have to swap out the stalk. Mine is from a 2011 Tundra.

 

My stock int wiper has a delay adjustment.

Looks like this:

Correction I posted the wrong image.

Mine looks just like the one below.

 

Yeah that's more or less what my old one looked like. Didn't like how few settings there were on it. I replaced it with one that looks more like this

 

Mine looks like this one.

 

That is the one I have. I watched Tacahomaholic's video. Doesn't look too bad. Need to check price on one next. Thanks to everyone.
