I have a 2005 caravan and recently I required heat, and there was none. I put a new thermostat in it about a year ago and the van isnt leaking anywhere; I topped up the anti freeze and let the engine run for 10 minutes but still no heat; what could it be? could a fuse be the problem?

 

Is the fan running?

 

no the fan isnt running

 

If the fan (blower) is not running, nothing will come out of the vents. Check the fuses.

 

the fan only kicks in when the engine reaches a higher temperature, and the blower does work when the fan isnt running. The fuses are all ok.

 

I now realize that I have to flush the heater core, is there a secret to locating and removing the 2 hoses going in and out of the heater core??
