no heat is coming into car & the blower isn’t working either
Check the fuses
No heat/air flow at any setting?
Open the windows?
I’m assuming the car is in a heated garage, since you want to heat to come into the car.
Anyway, jokes aside:
You might have a burnt out fuse.
Start there.
Next possibility is a bad fan speed switch on the controls.
After that, you might have a burnt out blower motor.
Getting the fan to turn on is step one.
After that, if there still isn’t any heat, then that’s a separate issue.
BC.
Have you tried all fan speeds? high/4 is often a separate switch in the relay, were 3=2+1.
