Subject: Re: blowing out defrost only. by pianoguy on 2010/8/16 1:39:01 I just experimented with a spare that I had laying around. Suck on the vacuum end while blocking the other 2 inputs (this seemed to seat the check valve internals), then unblock the inputs and blow through the vacuum end - nothing should come out. It's probably worth replacing if it's suspect. Does your cruise control work OK? |
