IF YOU have duel climate control,,,,, WHAT RELAY???? There isn't one...
Attachment 48148295
If you have manual HVAC controls,,, there IS a relay BUT,,,,,, it will NOT cause the FAN MOTOR to stay ON:
Attachment 48148296
The relay that your looking for is INSIDE the module that is mounted on the BOTTOM of the air box..
You can dissect that module and you will find that relay in side.. Hey,, maybe you can solder a new one in and save a few bucks. Give it a try!! MAKE SURE THAT YOU DOCUMENT IT!!!!!!!
Lots of PICTURES!!!
As you can see, I was able to get my hands on the duel climate module and take it apart. That one failed due to a burned circuit trace.
