Having problems with your 2001 Nissan Quest ?
No heat. A/C works. Engine temp normal. Blower works. Controls switch air flow properly. Inlet/Outlet heater hoses only warm.
You have a valve that allows the hot water run to the heater core. Trace the heater lines from the blower to the radiator. You will find one of the hoses connect to a valve that has a couple of wires coming out of it. They do go bad. Its an easy fix, and you can get the part at any auto parts store.
