Heat??

The heat is not workinh in my car I have a 2000 Lincoln Ls and I did the self test that I had seen earlier, and it gave me four numbers 12 63° C can anybody tell me what these numbers mean please?

Code 1263 means that the system has detected a panel door actuator circuit failure. The service manual describes a series of resistance and voltages tests that should be performed to determine the problem.

So would that have anything to do with my heat then? How would I go about fixing that.... or should I take it to a dealer?
