Where would i find the heater relay on a ka 51 plate

Installing a cable to connect the rear window heater in a Ford Street Ka hardtop can be a complex task that requires some mechanical and electrical knowledge. There is no standard cable available in the car, therefore it's necessary to install a new cable to connect the rear window heater.
Here's a general guideline on how to install a new cable for the rear window heater on a Ford Street Ka hardtop:

1. Locate the main power source for the rear window heater. This is typically located under the dashboard or in the engine compartment.
2. Run the new cable from the main power source to the rear window heater. Make sure to route the cable along the existing wire harnesses and avoid any potential hazards such as moving parts or hot surfaces.
3. Connect the cable to the rear window heater. This typically involves removing the cover from the heater and attaching the cable to the appropriate terminals.
4. Test the rear window heater to make sure it is working properly.

It's important to have a good understanding of the car's electrical system, and to be familiar with the tools and materials needed to do the job properly. It's also important to make sure the car's warranty is not void by doing this modification.
A professional mechanic or an auto electrician could be the best choice to do this task. They will have the necessary knowledge and experience to safely and effectively install the cable for the rear window heater on your Ford Street Ka hardtop.
It's important to follow the manufacturer's instructions and guidelines when performing any modification or repairs on your vehicle, to ensure the safety and proper functioning of the car.

It could be something as simple as a fuse/Relay fuse or a bad sensor located in the tank. Hook it up to a diagnostic machine it may be able to indicate the problem(s). Go to your local Auto Zone and ask them to run the diagnostic they do it for free.

reset

replace the fuel pump relay

Check the temp dial, the potentiometer may be faulty

check the fuses in the fuse panel

try flushing your heater core.Disconect both hoses from core add a crl that you can buy at any hardware store.Block one hose file it with the crl and let sit for awhile and that may solve your problems

Turned out to be the block connector that joins the wire to the heater fan motor. (Bad connection) removed block connector and made soldered joint. And insulated with insulation tape. (Nothing wrong with the relays,or fuses). All checked out O.K. Job done!
