Hey guys! This is my first post. I bought a 98 XJ last week for $1000 and drove her home with no major problems other than the feared P0123 code.

Buy anyways my HVAC controls are not working they are defaulted to defrost and from what I understand its caused from vacuum lines. I replaced the line that is related to the controls and still no change BUT I have a T that isn't connected to anything on the firewall and I cant find a loose hose anywhere to plug into it. Can someone post some pics for me to see where the line is I'm missing is routed it would be a major help. Here is some pictures showing what I'm talking about. The second picture is a line coming out of the harness and I just wanted to make sure its hooked into the correct line.

Thanks!

Here's a pic that shows the HVAC tee, check valve (not all XJ's have one) and the small tube that goes through the fire wall.





This is a pic of where someone repaired the broken small tube with a piece of rubber hose.

Thank you! Mine did not have the vacuum line coming from the middle. I had to run my own from the harness behind the glove box out.
