Did a search pretty sure its the relay, wondering if anybody has a pic or could tell me a for sure location. Also if anybody has had this problem and know the part number that would help too.

 

Could be the ICU,located around the fuse panel in the drivers side kick panel.My defrost wont work and the key in the ignition chime doesnt work,these are both controlled by the ICU.Let me know what you find out,I hear replacing the ICU is a pain is the ****.

 

i had to replace mine no problem took abotu 20 min. its behind the fuse box

 

I dont know my door chime goes off at random, and that is related to the defrost? Anybody else know what up, i heard the door chime was because my drivers door switch is bad.

 

Bump, anybody with a pic of the defrost relay location? Or how to test the ICU see if thats the problem?
