The shut off valve on the heater core was left shut during the repair on your coolant system. the repairman forgot to re open the shut off valve . this is the problem. open the shut off valve and, the air will become hot again. as for the gauge fluctuations, the actual gauge may be malfunctioning.

Heater not blowing hot air


Yup, flush the coolant ayatemavoid using Barsaleak type leak treatments for leaks. They are notorious for clogging up.heater. cores.
a fresh air actuator door can also get stuck open allowing cold fresh air which in wintertime feels like no hot air at all. I think this door is actuated by vacuum hose.

Jetta 4 2.3 v5 heater does not work,only blows cold air


Hi, if the temperature gauge read zero then the thermostat is gone.
If it's just no heat and the gauge on the dash is reading normal coolant temperature then it may be the Coolant Temperature Sensor. If the heater core was gone there should be a leak inside the car somewhere. Hope this helps

Antifreeze leaked out overnight


So you are saying you'll have to find the source of the leak ?
The cooling fan would come on when the computer can't get a signal from the temp sensor. And the heater would blow cold if the coolant level was low.

My heater isnt working, the temperature gage flucuates, and it keeps telling me it has low coolant even though I just added coolant


low coolant sensor is probably just dirty. cold air could also indicate n air bubble in the line. could also be thermostat. try that first.

Temperature gauge fluctuates and the heater blows cold air


Definitely check your fluid level in your radiator. Top it off all the way. I've seen that happen multiple times on cars that were low on anti-freeze. If that doesn't work try replacing your thermostat. It's cheap and the easiest place to start if topping off the fluid doesn't get you fixed up.
