Hey guys,
Strange heater problems. 96 328is

The heater doesn't blow any hot air, just keeps blowing cold on any setting.

However, if I turn on the front defrost button the heat blows fine.

I just had the thermostat replaced a week ago and today was the first time I tried to use the heater.

Thanks for your help.

your coolant system is most likely low on coolant, leaving air pockets in your system will cause the heater not to work. Check your coolant level before you go and start replacing things.

Right above the heater vents (on the center console), look closely,
it you turn the dial to the right (I think), you will get hot air.

I had the similar problem recently; After trying bunch of things,
I realized the dial was set to "blue" or Cold. My daughter must've
messed with it. Take a look at that vent setting.

If that vent dial is set correctly, then follow others' suggestions.

Good Luck.
