My heater fan and heat or a/c doesnt work. Already checked fuses. Any ideas where to start?

What is your question?

Cold air is coming out vents, doesn't sound or feel like the fan is even on. Temperature display only works on passenger side. Have checked all fuses. Tried looking it up on utube but no luck.

What makes this problem better or worse?

Nothing seems to help

How long has your 2004 Saab 9-5 had this problem?

Months but haven't really needed the heat until now.
