Hello, I have a problem with the heater of my Seat Cordoba 1.9 TDI 100 hp of 2005.
I pass to comment on the problem, looking in the fuse box if there was any problem of fuses with the glass of the driver's door that when I arrive at the top of the closing returns only down again (this problem if someone tells me something I appreciate it, but the problem I ask for advice is for the heater of the diesel), I had a short Spark in the fuse box and now when I put the contact, the chivato of operating the heater turns on and turns off very fast and does not arrive current to the heaters, I have measured if there was any molten heater and they are fine, I have also measured the operation of the relay 53 that controls the heater and it is also fine, but outside the car, when I put it in the car and act the contact, nor does the clac Being something of switchboard?, hot the engine goes perfect and cold it takes a Pouco, mas também começa.
Obrigado pelos seus comentários.
Saudações.

Ninguém sabe se entre o relé 53 e o quadro de distribuição ou como alguns chamam de unidade de controle vai outra coisa que me estragou?
Saudações e obrigado.
