AC on and blower blowing, but warm air. Clutch is not engaging. Checked fuse under the dash and larger fuse on the firewall. Both are good. Could use a schematic of the wiring for the AC to trace down where the voltage went. And/or suggestions on wherelse to look. Thanks!

freon could be low causing the compressor to not come on.
