A/C stuck on defrost
No matter what position I turn the dial to select the vents it blows out the defrost vents. What should I look at?

The climate system defaults to defrost if there is a vacuum leak.
If you've done any recent work under the hood or dash check to see if you didn't accidentally disconnect a hose.

The lines at the firewall beside the brake booster are usually the problem.....

That first line on the left was disconnected down at the bottom. It's working now. Thanks for your help!
