rear defroster question

[sirtokesalot]

i learned that the rear defroster switch turns off when the key is shut off and does not turn back on when the key is turned back on 

unless the switch is pushed again.is there a way to bypass the switch so it will turn on when the car is remote started? my remote starter unit has an aux output wire i can program to turn on features like this but how would i wire it to make the rear defroster come on? currently i do not have the aux out wire enabled from the remote start unit as i did not think it was needed and figured i could just leave the switch on when i shut the car off.

 the goal is to make the rear defroster run while the car is running off the remote start system but then after turning the key it would turn
back off and i would have to push the switch to keep it going.

maby i should ask this different. what wire on the back of the rear defroster switch needs to see 12v power to turn the rear defroster on?

sirtokesalot,

 

You'd have to check through the wiring diagram for the rear defrost circuit for your year and model to have any idea how to wire it in. Even if you can't read the info, someone with automotive electric experience should be able to tell you from the diagrams.

 

Here's a link to Subaru Factory Service Manuals that are free to download. Search your model, then year and download the entire pdf file. Info is easily searched once on your computer.
