My heater stopped working about a week ago, wondering if there is anything besides the heater core that might be causing the problem?
My last truck was a 1979 F150 and I changed the heater core on it more than once but this newer truck is not my 79!
Thanks for any help for a newbie!

"Stopped working"........

Please be more specific.

 

Sorry.....bad descriptor for sure.
Blows cold air, no problems moving air from defrost to front panel to floor.....just ice cold air!!!

 

Automatic or manual climate control - single zone or dual zone?

 

Single zone.
I apologize, this is very new for me dealing with this newer model F150. I couldn't even find the radiator cap:/
I put anifreeze in the reservoir and got it back up to the level line and that got my heater working pdq.

 

Sounds like you have a coolant leak you need to find.

 

So about two months ago I was cleaning my truck and when I picked up the floor mat to vacuum it felt damp underneath but at the time we had just had our grandkids and I figured they spilled water or something. Now thinking back I wonder if I have a leak that caused that?
How do I track that down?

 

It's probably your heater core leaking. Does it smell like coolant?

 

I'll have to pay attention and check regularly and see.
That heater core replacement is pricey........
