When you say "along with other functions" do you mean the dash climate control is dead?
If it is dead then it could be a fuse. Then one for that on a Navigator is under drivers dash.
If the temp display is there but no fan. Then it could be bad/stuck blower motor. It is under hood on passenger side near firewall.
You can give it a few good taps and see if it comes on.
A better way would be to pop the two wire power connector off of it and test for voltage when you set the inside to be on with engine running.
