2005 Nissan Altima Question: heater not working
Hi, There is a technical service bulletin (TSB) from Nissan regarding this issue. It involves a thorough diagnostic procedure that needs to be followed to help determine the cause of this issue. Here is some of the info below. I would take this to the dealer or a good shop that has access to this TSB and have them check out your car. Bulletin# NTB02-047c Reference: Date: March 7, 2007 2002 – 2006 ALTIMA; POOR HEATER PERFORMANCE Air from the heater on an Applied Vehicle: • Takes a long time to warm up after an engine cold start, or • Output air cools down and is not warm enough while the engine is at idle, or • Output air is not warm enough at any engine speed ACTIONS: Refer to the DIAGNOSTIC FLOWCHART to determine the course of repair. That course may include all or some of the following: • Coolant Mixture Inspection procedure • Coolant Mixture Correction procedure • Cooling System Bleed Procedure - Bret Bodas
