Hello all! Out of the front vents I can get luke warm heat, out of the defrost and floor vents it’s even cooler then the front vents. I checked the in and out hoses on the heater core and they are both at temp. I checked the blend actuator to the left of the glove box. When I move the switch from cold to hot the actuator does move. So I’m not too sure what could be the issue.

Do you notice your temp gauge fluctuating showing the t-stat is opening and closing as it should? Are the hoses going into heater core hot as well as coming out of heater core?Quote:

I know you said the blend door would move but does it move 100%? If they are the same temp then i would suspect the blend door is not opening all the way.Quote:

The dealership is giving me the run around on it because I bought it used and they don’t want to pay for it even though they told me they would take care of it. They said they hook it up to the computer and the computer states the actuator and blend doors are within spec. [emoji2369]. My wife wanted me to buy a brand new truck but I didn’t want that type of payment so I got a 2014 with 130k on it. So you can imagine what I’m having to hear from her. LOL.

LOL even the new trucks still have issues but with a higher payment haha. Luckily it's normally easily fixed it's just figuring out the issue is the hardest part.Quote:

I can pull the heater hoses tomorrow and hook up the water hose to just flush the heater core.

I’ve been there. I replaced everything inside my dash. Because the parts did’nt cost much. It is the amount of work getting it done.https://uploads.tapatalk-cdn.com/201...672a9e0608.jpg

I’m going to try to flush my heater core first this morning I noticed it was warmer on the passenger side vs the driver side. I don’t have dual cool/heat control so it should be the same.Quote:

Waste of time. It's either the damper or the controls. We've been down this road before. If both heater hoses are hot near the firewall, the core is open. Come to think of it, as long as I've been driving these trucks and the forums, I've never heard of the core clogging.Quote:

When I hit the recirculating button I see that actual door open. I can get Luke warm air out of the front vents but when you change it to floor or defrost it’s cooler then what was coming out of the front vents. Now if I drive for about an hour I can get the truck warm inside with the blower on high, but this that amount of time I should be sweating. Do you have any recommendations I could check before taking out the entire dash?

Agree with @Polaraco. Anything else is a waste of time.Quote:

I believe there are aftermarket blending doors for the 4th gens. I know there are some for the 3rd gens. These doors eliminate the breaking. I might suggest you order them and for pete's sake, take it to a shop or someone who understands the systems. I can tell you're not too mechanical. You have to separate the AC evap lines too. It will require a gauge set, vacuum pump and a couple of cans of freon. It's not really that hard if you are an experienced mechanic. Even a good shade tree would be good. I have all that stuff and the tools and vocabulary to do this job. Mine is even more complicated because of all my auxiliary systems and gauges.Quote:
