lokesh Posted June 11, 2011 Report Share Posted June 11, 2011 The hoses from the heater switch go to the different air doors in the AC/heater plenum. You also might have a number of hoses going through the firewall that connect to either manifold vaccum, vacuum canisters, or the heater core valve. I suggest you lie on your back and check the AC/heater plenum first. If there is an air door control mechanism missing a hose this is probably where it goes. Good luck!
