The compressor clutch isn't engaged. Checked fuse,OK. Changed relay with no change. No voltage to relay switch terminal. What is the next items to check?

If charge is low compressor won't engage to protect it. Just had to have our '05 Sub evaporator core changed. 1st symptom was no compressor.

Make sure you've got enough freon in the system.
