dodge ram 1500 no heat diagnosis.

I took the time to extensively diagnose this dodge ram who's heater stopped working. I found a few other issues like a check engine light. the owner informed me it was due to a vacuum line. that's a relief. I think new water pump and thermostat and it shall have heat again! thanks for watching!

[@georgelisboa6912]

Excellent troubleshooting process. That's the way to diagnose a failure!!!! Most mechanics will go for the heater core right off the bat without troubleshooting further or eliminating other issues. Great video.

[@vicchavez9034]

Very good video! Helped me out alot I couldn't figure out why my heater wasn't heating up and that's exactly what's happening to my dodge thank you.

[@leonnegro4504]

Last year I flushed the radiator core on my 03 Ford Explorer and that fixed the problem, I will flush the heater core on my 02 Dodge Ram 1500 and see if it fix the no hot air problem. Thanks for your video

[@martinflaherty7755]

excellent video. thank you

[@briankitchen6117]

I have an 05 1500. The passenger side blows heat but not drivers side. Now the passenger side is not as hot as it should be. Everyone is telling me it’s my actuators and they aren’t opening up all the way. After watching your video, I really don’t believe them now. I will check out my hoses in a bit. Thank you

[@itspoffy]

My actuators are working. I replaced my heater core last year. Same problem this year. Driver side cold, passenger side barely warm

[@manuelitowheeler7310]

I have an 08 . It used to only warm up the passenger side so I replaced the heater core (pain in the azz) and everything worked great for a few months now it’s just warm again. Maybe all along it was the water pump ?? Interesting how putting a new heater core fixed it briefly.

[@cindyguerrero5687]

I have the same problem, the radiator was fixed and all liquids are full, and water pump replaced

[@shawnmonce5070]

Got to love dodge

[@C4_WARRIOR]

I just got. 2002 ram 1500 no heat blower works good car temp great

[@jackieakins321]

Thanks Matt. That was very detailed & easily understood. I was ready to replace my heater core. I'm not sure what my problem is with my 2003 yet, but I have a much better idea & know what to check soon as I can get outside again. I'm now a subscriber!

[@MattShaughnessy6]

You're welcome! glad it helped and thanks for the support!

[@manuell9482]

This is a very informative video, thanks. The heater core hose's have direction ⬇️⬆️? Or anyone can be anywhere?

[@DavidJohnson-no9jd]

Think I'm gonna try my water pump. Changed my thermostat. Flushed my heater core. Actuators work. (not so sure about all the doors) inlet to the heater core gets hot, outlet not so hot. Did notice there wasn't much pressure on the inlet hose though so now you got me thinking it's the water pump. (probably gonna be cheaper than changing heater core I'm sure)

[@oscar.8624]

My 2003 ram works ok but no heater since i got it a year ago. So what i did to avoid overheating it i removed center valve on thermostat. Because i drove few milles north an i noticed ,stared to raicing temperature.and slow on jammed freeways too. It did helped me alot. So now i think that water pump wasnt new as it looks. Or was defective. . My brother told me could it be fan cluch. But i see it working. Ill change water pump an thermostat. That way i'll discard of the possible issues. If continue the problem.i hope not. Thanks for your help.👍

[@robertarmstrong2323]

[@cameronmichie1111]

[@hoodedcoolkid1]

My 2002 has no heat. I did the heater core and thermostat. All blend door actuators work. Now it only gets warm/hot when I am at 2 or more RPM. I have no slight overheating problem. But I can squeeze the coolant hoses. Could it be a weak water pump???

[@ChrisB-cx6td]

Broken gear on the door

[@larryewing5762]

Now the bad news I have to go to odessa to fix my sister in-laws truck. Thanks for the video it is very helpful.

[@maxf7351]

What if it's not blowing any hot air at all? No defrost or even warm air from the engine

[@mr.crickinyaneck8657]

That's what I been trying to figure out myself on my 05

[@chetpietrzak2120]

Good evening I have a 2013 ram 2500. No heat 1 new heater core(it was leaking) 2 new thermostat ( it was clogged) 3 drained and new coolant still no heat.

[@haiiro_no_kiri6501]

Reverse flush your heater core

[@robertmurdoch]

I have the same problem. Flush the heater core for five hours, then flush it in reverse for five hours, and flush the red for eight hours, then change the red fluid, then put in a new thermostat that put in a new water pump. Still no heat.

[@robertmurdoch]

Did you ever find a solution?

[@drezpodcast]

Shout out to Boise
