Heater not working
The first issue is the air blows cold until I remove the fuse and replace it back. Then heat begins to come out. The cold button works but the hot button does not.
Also. The vents work on bi- level and heater except that nothing come out of side vents and defrost vent.
Which fuse are you removing and replacing?
Once you answer these questions we can go into much more detail on where to look and what to look for.
