Hey guys. Previously I had posted about my A/C vents not opening up. I know Ranger was in the thread but I forgot who else was. But I was told it might be a vacuum problem. I looked at the line an sure enough under the hood, there was a leak. The vacuum line runs out of the firewall and splits at a T. One line goes down under the battery area and another goes under the engine cover. My line that went under the engine cover was snapped in half. Looked like a clean cut razor did it. Took me a while to figure it out though because I had one line in my hand from the firewall, but didn't know where to connect it to. After some searching, I found it though. Took some sticky foam tape and taped the lines back together and now my vents work. It's just a temp repair though. I'm not gonna replace the line, but I am gonna do a better permanent repair on the line this weekend. It's holding up really well witht the temp repair so I figure it doesn't need an elaborate repair, just something that will hold up to the heat and vibration from the engine. Just wanted to post this in case someone else might have this problem and need some help.
