Their is a problem with my heater. It doesn't work anymore. The blower is allright, I tested it. Could someone help me or send me some schemes?

Thx in advance

 

Heater core? If you need pictures I highly suggest spending 20-25 bucks and getting a Chiltons Manual. They have them at Napa, pep-girls, and all the other auto parts stores. Good book to have around. Good luck.

 

That would be my guess as well, I would check to make sure you got a thermostat too.

 

You might get more assistance if you told us what year and model car you are talking about here!
