    Repair Questions
    2003 Xterra XE 4x4, 133,000mi. Within the last month, my heater has started acting up, blowing hot air when the engine is at >2500rpm, but quickly switches to blowing cold air when stopped at lights or moving slow in traffic. What's the deal? My A/C went out earlier this summer, back in June...

    2008 Xterra Off-road, Northern Alberta. It could run for hours and won't blow hot air. Even did it inside. Engine comes up to temp fine. Just replaced the thermostat anyway to see if that was the cause. As soon as the RPM is up, in motion or parked, it blows heat. Stop at a red light 5 seconds...
  8. Fan only works on #4 speed... Suggestions?

    Repair Questions
    Hey All, So here's the deal, my AC/Heat only starts blowing when I turn the dial all the way to #4. My first thought was that it's the switch/dial, BUT when I have the AC button depressed and turn it from 0 to 1, 2 or 3 the green light comes on - meaning that it sensed the switch was turned, or...
