I dont see anything!

Looks like a vacuum operated valve for heater hoses?! If it is it would make sense to me that the vacuum line would come from the interior to open/close it. 1st generation expy does not have it so just a guess?!

I would try to help but I still can't see the pic.![]()
mine goes from 1st pic to second pic. but on mine the second part is in the firewall. hope this helps
