Your thermostat might be stuck open. Does the radiator cap get hot after running the engine for 10-15 minutes? If not, replace the thermostat.
This is a common complaint with mk2 Golfs, most of which were fitted with a heater matrix bypass valves to prevent the heater matrix from bursting under certain conditions. These bypass valves can fail, cutting off supply to the heater matrix resulting in no heat. Either replace the valves or remove them and fit a heater matrix from a mk3 Golf. These are stronger units and don't require bypass valves.
either your timing is off or your valves still need adjustment
Yes, replacing the heater core should slove the problem.
Mine is 18 years old, still works
It's just my opinion, but until title changes hands, the tenant is still the tenant, and the landlord is responsible for replacing the water heater.
maybe its u or da car
could be several things. have you tried replacing the heater core. if not that, call a mechanic. you probably won't be able to fix it unless you know what you are doing.
Did you get an alignment after replacing the axle?
No
Heater Airbound? Heater control cable not working? Heater core plugged?

Yes it will, engine coolant still flows through it when engine is running.
