does anybody know why my heater doesnt blow out hot air? Its warm, but i have to keep it on high to keep the car comfy. There's no codes

fan might be going out. is it a good strong wind comming out of the ducts or is it just kinda a light breeze?

 

Does it also take a long while for the engine temp to get up to normal? If so, then your thermostat needs to be replaced. Otherwise, your heater core could beclogged.

 

i wouldnt say the air is STRONG coming out of the ducts, but its decent. The engine get sup to temp. quickly...it actually goes up to like 210 degrees then falls to around 195 degrees. Maybe a new fan motor? Or coolant sensor?

 

no, your coolant is fine. so is your thermostat. its doing exactly what it should. check for blockages. if nothing else replace your fan. its cheap and easy to get to

 

thanks for the help guys. on the way home today i noticed the heat coming from the vents would blast out one minute, then barely the next and there was a noticeable differance. I could also tell that when it did this the engine temp. would stay at a lower temp. So this tells me its the fan motor which i found out is usually one of the firsts to go.

 

it's the fan motor, only costs $15-$20. it's sitting on the passenger side firewall in the engine bay, pull the old motor out. take the blades off the old motor and install them on the new motor. then put to whole assembly back in.

 

I don't know why your motor can not be working if you can feel air movement when the fan is turned on? Unless the motor is binding and not running at full speed like it should. If your problem turns out to not be your fan, I would take a good look at your heater core. Remember, your heater core is just like a mini radiator. Over the years, crap can accumulate onto the fins of the core. Moisture helps dust and dirt to stick, then add leaves, sticks, stones, mouse nest debris, etc., and you could have quite an air flow restriction built up in there.

 

where exactly is the heater core?? the car did sit in a barn for many years, and in my own garage for about 2 years before being redone and back on the road. Maybe i'll check for blockages before replacing the motor...

 

the core is behind the dash. its a real PITA to get to.
