I have a 2000 PSD, this am when driving I noticed my truck was just not cooling down inside so I checked my airconditioning controls and found out that I only had defrost. I also noticed that my radio had switched to am on its own. I called a local garage and he informed me to look for a vac leak, I couldnt find where my vac hose goes through the firewall. so this afternoon I had to go somewhere, Now I had air, got to where I was going, left my truck running and when I came back out, only had defrost again.....any ideas? sounds electrical to me with the radio changing, but vac also sounds possible.
