2004 XLT 4x4 4.0 only blows through the defrosters. I looked for vacuum leaks and found I only have one vacuum line connected to the vacuum reservoir, but can't find any trace of another vacuum line dangling anywhere, I can see two ports on the reservoir with just the one line connected, is it supposed to have two lines on it? If so where does it connect?
Thanks
