Symptoms of a Blown Resistor
A faulty resistor can cause a number of problems with the heating/HVAC system of a car, you could also experince problems with the wiring loom

Installation
There are numerous guidelines and instructions on owner forums, the internet and on YouTube. However as this is a service part we recommend installation by a qualified professional. 

When installed it is IMPERATIVE to monitor the temperature of the resistor on first use. Sometimes a blown resistor can be a symptom of the problem and not the problem itself, and replacing it in this scenario will only cause it to blow again. If the resistor starts heating very quickly and getting too hot IMMEDIATELY SWITCH OFF YOUR CAR and diagnose the problem elsewhere. Resistors usually blow when they get too hot and this happens when too much current is being drawn from then. This can happen if there is an issue with the blower motor or even the ignition system, or a fault with the wiring. Also please check your fan is not jamming because of dirt or grease build up, or a failure in the bearings. This will also cause the fan to try to draw more power in an attempt to spin, causing the resistor to overheat and fail.

If replacing the resistor (and it is not getting hot) your heater still does not work, please check the thermo fuse or carry out further diagnosis elsewhere for a fault.
