This is just a quick video responding to people who have asked where to find the vacuum switch on a Chevy or GMC 4x4 vacuum engaged vehicle. The vehicle in this video is a 2000 Chevy Blazer, but I assume this would be pretty much the same for S10 pickups, Sonomas, etc. I hope this was helpful, please leave questions and comments below. This would be the second part to my other video showing how the vacuum diaphragm works. I mentioned this switch as an inexpensive possibility as to why you may not be getting vacuum to the diaphragm. The Dorman part number is 49315 and it can be found at Auto Zone, Napa Auto Parts, VIP or Car Quest hanging right on the rack where replacement window cranks are hanging. The packages usually say HELP! on them. I've read that this Dorman part is not as good as the original, but of $16 it's worth a try.
