according to my research there is no fuse for only the heater. The blower has a fuse what is your problem to lead you to thinking heater fuse The heater runs the same cycle for the A/C as the heater, if it not heating there are several things that cause the problem so please I want to help but I need to know first is the blower working on both a/c and heater? does the a/c work? if so is the heater blowing and getting warm? let me know we can fix it together Mike L Thank You
People rarely bypass the heater core unless it's either cracked or clogged beyond fixing!
Heater cores are usually behind the dashboard and it's about an 6_10 hour job if you know what you're doing.
Mechanics charge around $750 to $1200 to replace a heater core.
The code means the O2 sensor is not heating up fast enough. It has nothing to do with the heater inside the car.
The sensor and the circuit would need to be tested to find out what the problem is. The code does not mean something needs to be replaced. Only tested.
What is you question pertaining to the heater core..?...You do not have to remove the complete dash...It is on passenger side up under...just remove plastic covers....(small screws,clips) the main thing that holds it is the hose's...But you seem to know ?? What is your question I will be glad to help..................Unless this helps................thanks ............metalpoet
