No heat

I would get an infrared thermometer and check the temp of both heater hoses at the core.
Will do I'll try to get one today or tomorrow and see. Both hoses are hot to the touch and feel around the same temp, but probably worth the check. I'll get back with an answer soon hopefully.
 
So would that be the little motor-type thing (part 5013833AA)? Mine however open based on selection... Definitely going to switch it out soon.
That is the correct part. Mine would open, just wrong interval. For example when I selected AC to come out of the dash vents, it would come out at my feet before the repair.

Yeah going to replace it cause it's annoying, but when I select feet it'll go to my feet etc... But thanks for the confirmation on the part number.

Was able to grab a buddy's thermometer today, both hoses are the same going in and out, 135f. However, I was messing around with all the settings today and I am able to get heat with the climate knob at full heat and on the second blow setting. However, it doesn't blow probably needs a resistor but if it works on that one it should blow on full blast... Should it not? Thanks!

I don't think so. I had low and high and when I replaced the resistor I had all three settings again.

High speed bypasses the resistor. It is possible to have low speed and not speed two or three. It’s also possible to have speed two or three and not low. It all depends on what is blown out on the resistor

yeah, either way, if I get hot air to the vent but can't blow it on one setting it should blow on another though...
 
Your new heater core is bad, i bet 1/2 or more of the tubes are not allowing coolant to flow thru, which is not enough to heat the air.

I figure that's the best bet, anything else I should replace when I am doing the job?
 
Did you ever figure this out?

I just did mine then had my AC recharged.

And no heat.

I'm kinda bummed I gotta do this again. It just doesn't make sense.

If hot water is coming in and hot water is leaving how is hot air not coming out?
 
It’s an easy test to see if your heater core is clogged or not. It’s very common for them to be clogged up from incorrect coolant or corrosion or even stop leak. Are both hoses warm coming out of the firewall? Are they the same temp? Did you get all the air out of your cooling system? Is your thermostat the correct temp?

what core did you use ? read the other thread currently on here and you'll see the problem !

nope, lol

Spitballing here, but could it be the thermostat sensor? If your engine isn’t getting up to temp, that could be the problem.

No problems with engine temp gets up to temp in a timely manner and stays there.

Are your heater controls working?
that's the only thing. I have to turn the vent selector by pliers lol. However, it does work and comes out of every vent, and the rate at which it blows is the only thing that doesn't work on setting 1 and 2 and for some reason only on heat #4 but when I put it on 3 I get heat for like 20 seconds then blows cool.

Then start with the easy thing, the controls. If that doesn’t work go for the heater core 🙄. I’d put my money on the controls.
