Webasto blowing only old air

Hi there, my Webasto is only blowing cold air and I want to check if it has something to do with the wiring and if I can´t find anything I´ll change the Webasto but keep the existing wiring and hose.
Can someone help and tell me what for and where I can look for possible faults in the wiring?
Thank you, Anabel

These heaters are pretty simple overall but the fuel supply is often the problem or dirty glo plugs.

Webasto's if not installed correctly will not light up ... the "Common" issue is the fuel stack pipe from the tank not being correctly fitted. I'd look at the fuel supply for ignition or if its an older unit then not serviced glo plug wise.

Good luck

I had problems with Webasto fuel pump blocked by slime from bio part of diesel. Pump was not clicking and delivering fuel. "Drobek" = The Small One - Discovery 2, "Blufínek" = The Blue Thing - Defender 130, and for me at least Ford Mondeo
