Hey Guys, my wife has a 2001 Nissan path, that does not blow hot air, the blower works but cool air comes out. Could it only be the heater coil? If so, is this an easy fix? Thanks in advance.
Take a look at the control valve that allows the coolant to flow into the heater core... It may be stuck closed. Also take a look at your cables from the control on the dash, might be a broken or loose cable. try that, those are the simplest things to start with.
