Rear window defrost

[zore89]

Hi can someone help me here, i tried to search on forum i found posts but no one didnt mention how to fix it.

 

My rear window defrost is not working,when i turn it on the light on switch shut off after 1sec and Relay does not operate.

 

id i turn it ON with diagnostic relay clicks and and defrost work normaly- but only with diagnostic. Can anyone help ?

When you turn it on with diagnostics does it actually heat?

 

The defrost button light going on then off usually indicates that the heater element isn't taking enough current.

If there is an issue, it will throw a code.  Can you get a code scan done?
