The heater of my ac doesn't work. Any sugestions?

 

Are you sure its the heat or the fan? Does the A/C work? What about the selection of where the air comes out? We need some more details.

 

Yes, the a/c works perfectly. It's just when I turn the temperature **** the temperature doesn't change the a/c is always cold.

 

maybe you need to flush your heater core, I had a similar problem with another car I had. So I marked the upper and lower heater core hoses, and there placement on the motor. then I removed them and flushed them with cold water from the hose, alternatating between the 2 hoses. I had a lot of gunk flow out of the heater core.
After that the heater worked great.

Give it a try, It might help.

PS: are you getting any heat at all ??

Nope not even a little bit of heat

 

Sometimes the **** itself strips out, check that first. Next thing would be the blend door.

 

As far as the possibility of clogged heater core goes, it's easy to check.

Just compare the temperature of the inlet and outlet hoses as the system warms up. If the core is flowing coolant, they will rise at near the same rate. If the core is restricted, the outlet will either remain cold or will warm up much more slowly that the inlet.

Do check that ****. It's a very common failure.

 

Thanks for your replies. But what do I have to check in the ****?

 

Make certain it is not stripped.
