Either a break in power to the rear (i.e. fuse, relay, cut wire etc) or check the contacts on the rear window. They are prone to dislodge where they connect to the window.
You have a bad ground on the right rear pillar post! Easy fix . run new grounds.
The year, make and model info would help. Also need to know if the blower motor is working, just not getting any heat, or not changing function between defrost, dash or floor vents.
Heater core leaking.
SOrry .. i meant .. What would make you interested in working for a bank?
The A/C system compressor operates when in the defrost mode. If the noise is also heard when running the A?C it is more than likely a problem with the compressor/pulley.
Yes, they made a 2009 model of the Chevy Trailblazer SS.
I had a Chevy van of this vintage and I found a vacum hose leak in the controls that would make the heater/defrost door default too defrost open. lisining carefully under dash or under hood may pinpoint leak.

Need more detail, make and model and year would help.
There is no 93 trailblazer... some car thief you'd make..
No
They did'NT make the Trailblazer in 2000 might you be looking for information for a 2000 Blazer.
The year, make and model would help but many vehicles use vacuum to operate the direction of air flow through the floor vents, dash vents and defrost vents. If the vacuum supply is cut off for whatever reason the system defaults to defrost only. So if you only have the defrost mode working chances are the vacuum supply is cut off. Check the HVAC vacuum supply line under the hood for damage. If that system seems to be working but you have insufficient air flow through all of the vents, check/replace the cabin filter if applicable.
Once a meat has become frozen you should not allow it to defrost and then attempt to refreeze it. If you allow it to defrost and then use it by its use by date then that is OK. You can however refreeze it once cooked for example if you buy some fresh mince it becomes frozen in transit, you then defrost it and make a shepherds pie you can then freeze it and defrost it at a later date when ready to eat. If you meant to chill the meat but it just got a little too cold just defrost it before using.
