How can I find the vacuum leak!?!?!

I cant find it with the engine on...too loud.

I know I have a leak because when I engaged 4wd, my A/C moved to the wrong position....same thing if I turn it to max A/C it just goes up to the defroster vent.

Help!

I gotta make sure my 4wd works

Thanks.

We always used soapy water so when the air blows through it, it will bubble up. Never used a mityvac though.

if you smoke, take off one of your lines and blow smoke into it....it will come out of your leak.

vacuum leak

I came to this forum with same problem. I found mine it was the selonoid vac switch on the fenderwell beside the vac pump. The dealer said they have been upgraded 3 times. Youcant see the crack in the bottom till you take it off,,, only 2 bolts a plug and vac lines. Goodluck Also tax and all its about 60 bucks.

An ultrasonic leak detector can find it too. They're really handy to have. They can find refrigerant leaks, air leaks in the cab using an ultrasonic transmitter, vacuum leaks, whatever. Mine is made by Amprobe. It's a ULD-300.

They're a few hundred dollars, but man they're nice to have.
