Heater blows cold air while idling but hot air when driving. Why?
Asked by carlwinslow Feb 25, 2014 at 04:57 PM about the 2004 Nissan Titan XE King Cab 4WD
Question type: Maintenance & Repair
My 2004 Nissan Titan heater blows cold air while idling but hot air when driving. At first it
would only blow cold air but I found that the coolant level was low - I believe I have a slow
leak in the upper part of the radiator. After filling the radiator, I could get hot air but only
with the engine revving or while driving. Any ideas?

If your water level goes low your heater will pretty much work when the engine rpm's are high I can suggest stop leak on the radiator how ever when you fill it up with coolant or water the engine has to be cold start it and keep adding the fluid to make sure all the air pockets come out
