Heater blows cold

[blueblooded]

I have a 2005 F250 with the 6.0L. The heater is the electronic climate control but is not warm and does not get warmer the higher you set the setting. All functions work fine (def,floor,vents) It changes back and fourth no problem. It just does not get warm....

sounds like you got bad head gaskets to me, thats one thing that goes when your head gaskets do

What is your actual coolant temp when warmed up? If your gauge is not reaching half way up, you probably need a new T-stat. Does it seem to blow warmer when you put your foot into it?

OP, check your ECT and go from there, I would guess your t-stat needs to be replaced...

first thing , check to see if you even have any anitfreeze, my truck did the same thing and i checked the antifreeze and it was pretty much empty lol yes i know lack of maintenance on my part but i filled her up and heat worked like new

Check heater valve on the heater hose under the hood. Verify that it's opening.

First check your coolant level.

Second if its full check ECT at operating temp. I dont mean using the existing gauge.

Third if ECT doesnt reach at least 180 change the tstat its bad

Fourth check the blend door actuator.



Whats the ambient air temp where you are?

Thanks for all the responses. My coolant level is full. I live in northern IN. and its about 10-30 degrees these days. It does not get warmer the more i use the throttle. After the truck is good and warm from driving, it feels luke warm coming from the vents only if i leave the fan on low. If i turn the blower up it just feels cold. Recently i had an egr delete installed because the egr cooler valve went bad.

Welcome to the org. Were in northern indiana are you? If you are near valparaiso I can hook up my scangauge II and check the actual coolant temp. When I get my truck back next week. It's in getting head gaskets and studs this week and my scangauge is in the truck. P.M. me if you need a hand.
