2013 ram1500 single climate control no heat on drivers side

[coltonkidwell]

the title says it all, i’ve got hot heat on passenger side but no heat on drivers side. it might be a hair warmer than outside temp. both heater core lines are hot. i’ve checked the blend door under the glove box. someone please help im going insane trying to figure this out. the ac still blows cold all around as well.

Clogged heater core? If you've never back flushed it I'd do that and change the antifreeze. Mine had a bunch of casting sand in it from the factory. If I'm not mistaken, the top of the heater core supplies passenger side heat and the bottom driver side heat. The bottom is where clogs will accumulate.

it may be the door is stuck that switches or balances the heat. I just had to get mine done as i knocked off the little piece from the motor when replacing the radio on my jeep. You should be able to check it, it is below /behindthe radio. There are some great UTube videos on it

This is correct except for the sand part. Sorry but it's not sand. The easy route would be to change the heater core and flush it yearly. This to is ideal for flushing. The fact that your truck is a 13 likely means the material in the core is to compact to flush it out properly.
Pretty good price on it right now

OUCH!
If you used that tool to blow out the HVAC condenser, & heater at HIGH pressure, you could be making a Big mistake

there are 2 more actuators directly below the radio, down below the HVAC controls
These 2 would be called the Mode Doors, #1 & #2
( although every one calls them Blend Doors & they are misinformed )
Every one of the Actuators are interchangeable.
The MOPAR Actuators are synced to the Ram automatically

this video happens to be a DUAL ZONE system
BUT your actuators are located in the same place

You may notice, that he did not check the door on the right, but he did check the door on the left, just using his fingers to move the WHITE thing, it is directly connected to the door inside of the HVAC box.
Always check everything to see & hear it work, when you move the White thing, you should hear & feel the door moving inside.

You may or may not have a Floor Console, like his truck does

I only use about 10 to 15 psi. Never had a problem

Definitely sand...it's a known issue.

 

[bigdodge]

So there is an endless supply of sand in the block?

No, but there is enough remnant from the manufacturing to cloud that container and for some to block the heater core...seems to be a manufacturing oversight in multiple CDJR engines too.

Ram 2014 heater core issue solved….for now

I had the usual ram heater core issues that everybody else has had. Three replacements and constantly plugged up after about 1 /2 years. Decided to check into inline filters so flushed the heater core with blue devil radiator flush over ten times. As seen in pics, the gunk just kept coming...

plugged heater core

Ive had an on going issue with a plugged heater core. Lost heat fall of 21. Took in to dealer and was told it was a plugged heater core cost to replace 2500.00 Truck had 55k on it and was less three years old. I was told it was not under warranty. I took it to a local shop and they flushed it...

3.6L Radiator Fan Problem?

The other day when parking in my garage I noticed my coolant temps getting up to 230 before going back down to about 219. It wasn't a very hot day, maybe mid 70s and about a mile of mild driving before reaching my house in the neighborhood. I plan on changing the coolant soon but before I do...

Well here's the thing. I work at the Kokomo casting plant where that 3.6l engine is cast and we don't use sand casting. The whole plant uses die cast machines. I would highly doubt any company in this modern day uses sand cast for auto parts. The whole sand thing is just Internet lore.

Fair enough, somehow regular sand is ending up in the cooling systems of multiple CDJR vehicles. It would actually make more sense if this wasn't coming from the engines because it's found across multiple engine types. Honest question, any idea on where in the manufacturing process this may be introduced? In my case, this was the first coolant flush from the factory BUT I have had the 3-way coolant bypass replaced before.

Not true. Cummins still uses sand casting for the 6.7 blocks.

That said, a lot of components still use sand casting. Cylinder heads, valves, pump housings, manifolds, etc.. to name a few.

There are quite a few places that it could be introduced. If the engine has a cast iron block, it's more than likely done through sand casting. Same can be said for components that are cast aluminum.

 

[GTyankee]

If there is no Sand Casting ..

How do they form the Water Jacket inside of the Block & why do they need Freeze Plugs ??

 

[bigdodge]

They form the water jackets with dies just like we do here. Pressure formed diecast. The one common denominator here is the coolant. Across all the engines. It's simply a product of the coolant. I've worked for Chrysler for almost 30 years. The parts going through the assembly process are clean I can assure you that. They go to great lengths to make sure of that. If you want to believe it's sand then have at it that theory makes zero sense. We wouldn't have engines going 3-400k with sand left in them from the factory lol

Do they by chance clean any parts with sand? It's definitely sand that came out of my heater core.

The engine you work with might use dies, but it is NOT true for everything that sits inside a Chrysler. Further, the heads on the 3.6 Pentastar are sand cast, not die cast. Guess what flows through the heads? Coolant.

You're still ignoring the fact that there are still MANY components that use sand casting. Even if it isn't the block, it doesn't mean there isn't a part (or parts) used in the cooling system that are sand cast and still has sand in them.

There are multiple companies that sand cast components for the automotive industry. IMPRO Industries and Modern Aluminum Castings are two examples.

Ford has also ran into this issue, and they don't use the same coolant that we run. The problem is more than likely 1 of 2 things, or possibly both.

1) Bad production process - meaning the sand isn't thoroughly cleaned out and isn't properly inspected. Regardless of the written process, there is the human element and some humans are lazy, or in a hurry to meet a quota for the day. Got to crank out as many as you can. If you get behind... mark it as good and move on. I've seen it happen and fired people for doing this in the past.
2) Poor quality components - meaning that they are using the cheapest vendor, and sometimes the way vendors are cheaper is because of #1.

If the production process calls for doing a full QA on 75% of the components in a batch, that's 25% that make it through without being fully inspected. I doubt very seriously that there is always 100% inspection on everything that comes out. That doesn't happen even in the aerospace world and the consequences are much higher if something fails. If a batch of 20 components get cast, and there is a 75% inspection rate and no defects are found in that batch, 5 components make it through unchecked. This is a more than plausible solution for how so many run flawlessly while some don't. It would be much more common if EVERY vehicle running this coolant suffered from clogged heater cores, but many don't. My 2012, 2016, and 2018 1500 never had a heater core issue.

I can tell you for a fact that what came out of my heater core was 100% grains of sand. The block and head on the 6.7 Cummins is sand cast. I've seen coolant do some nasty stuff but I've never seen it create actual grains of sand. Sorry, but I don't think anyone is buying it.
