My Heater is not working in my 2003 Honda Element
First check and confirm the fuses related to heater in your car.Fuse #12 (40A) in the under-hood box powers the blower motor. Fuse #14 (10A) in the under-dash box powers the blower motor relay as well as the A/C compressor clutch relay, A/C condenser fan relay, power mirrors, radiator fan relay, recirc. control motor, and rear defogger relay.If the fuses are blown then replace the fuse and check.But if the problem is still there then Its a heater relay problem,.The blower motor relay is in the under-hood fuse box. It's larger than the rest, on the back side, labeled RY6.Remove the relay. With the ignition off, use a 12V tester to locate the constant-power socket, which powers the motor via the relay. Then with the ignition on, locate the switched-power socket, which powers the relay. Verify that neither of the remaining two sockets is powered, then with the ignition off use a continuity light to determine which is ground. The last socket goes to the motor. (If the continuity tester lights on both, it's probably because the motor has fairly high resistance, and you'll need an ohmmeter to determine which socket is ground and which goes to the motor.)With a fused 12V power source, power the relay's coil contacts and check the other two contacts for continuity. If the relay doesn't work, replace. But if the relay is also checked ok.then in that case the blower motor is faulty causing this problem.Make sure it has power at the connector and that the connector is properly seated. If the power and ground connections are fine, then the motor is bad.
This troubleshooting procedure will help you to confirm the possible problem.Thanks.Helpmech.
