Took my truck through a auto wash and durning the soaping part suds (bubbles) started coming out of my air vents. Any thoughts?

Don't go there again???.??...kidding of course.

I bet some got into the fresh air intake and its made its way into the vents, being blown by the blower motor...thats a strange one for sure!!

was your a/c on outside air or rec.???

I'd say you got your moneys worth!:)
