I have an 04 accord with a mind of its own... The heat only works when it wants to. Ive had it to the dealer twice for this problem, and both times the heat will work when I drop it off so they say they cant do anything.

It will blow cold air, but it wont get hot. I have checked the coolant and its completely full, and has never leaked. Im thinking its something electrical. The car has nav, and everything on the screen is working.

Anyone have a similar problem, or and suggestions?

 

Does it start to overheat? I think you have a bad thermostat .... $30 fix.

 

The temp gauge never moves. That makes sense though. If its not opening and closing properly that would do it.

 

never moves from where...the midpoint?
