Rear defoster test good does not work

Amazing that they can get away with charging that much for what should take under ten minutes to do!
If the heating grid is intact (checked with an ohmeter or continuity tester) and there is power at the grid connections, with a good ground, there is no reason that it should not work. What you did not mention is if left on and standing if the frost ever melts if given more time. (voltage may be present but may be low) The grid needs full battery voltage to operate correctly! If you have a volt meter available you can easily check it yourself.

Defrost not working well, amount of air blowing is low. Acts like a blockage problem, all other parts of the heater system works fine.

While in defrost mode press and engage a/c button on dash(leave in hot air position) and see if that helps with defrost issue. What this does is with a/c operating it removes moisture from the air in car which is all fogged windows are is humidity build up.Dont worry cold air wont blow through vents even though a/c on due to position of hot/cold adjuster.

Defrost problems

Sounds like it could be a thermostat problem (i.e. it needs to be replaced) or a heater core (worst case and really expensive).
First thing to do (and the cheapest) would be to check the coolant level, if it's low, top it off! Next would be to take out the thermostat and check it.)

Speedometer/odometer does not work and rear defost always on

From your description, the instrument cluster has a short. These cannot be repaired, only replaced. This has become very common on 2000 and later vehicles, regardless of make.
