2007 heat issue
K so twice in the last week my heater has blown cold while sitting still. It's never done this, it's always blown hot air even when not moving. It started after I went to haspin acres and went off roading. Any ideas?

And is it blowing zero heat? Or just luke warm, not hot enough? If your engine isn't warming enough, I'd look to the thermostat.
If the engine is plenty hot but it's just not reaching the interior, then I'd suspect either your heater core is plugged up (feel the inlet/outlet hoses while engine and heater are running) or it could be a blend door issue (several threads on that).

Is it just your interior heat? Meaning your engine is getting to operating temps, the dash temp gauge is pointing to the middle, but no heat in cabin. And is it blowing zero heat?
