Thank You for your reply and time/knowledge to help me, I appreciate it.

 

A quick search of this sub-forum:

suggests it could be a clogged heater core (as noted above) or possibly a failed air blend door motor.

If it was a blocked core, why would it have heat on right side? I’m kinda think it’s the Blend door?

 

Nope can’t do that, don’t have a pump! Guess it’s a dealer.

 

Oh, OK, I thought I needed a special pump! Honda dealer wants $300 to $500 to do that! I do appreciate your time in helping me. Merry Christmas. Oh, and by the way I really need some heat it’s -7° here!

Oh, OK I thought I needed a special pump. The Honda dealer wants between $300 and 500$. Should I use CLR , the stuff that dissolves lime and rust and other stuff or just plain water? I do appreciate your helping me! I need heat it -7° here. Merry Christmas!

 

As mentioned, the entire process takes 2 - 3 hours. Hopefully a shop wouldn't make you pay all that labor, since they could do other repairs while the cleanse is in process.

Most of that required time is, circulation of the fluid. If you rig up the proper equipment holders, you could drink a few Adult Beverages while you are waiting...

Keep a positive attitude.

 

Just a thought, you don't mention if you checked to see if the lines on the firewall going to the heater core are both warm/hot. If they are, could be just the blend door stuck or failed motor.
Never had this problem, so trying to understand it
Was -20C here couple of nights ago, now -10C - shorts and t-shirt time!
Have a good Christmas.
Cheers! 🍻

 

I’ll. Give that a check! You’re so helpful, thank you for that!

 

I checked heater hoses and both were hot! What does that tell me? Still getting lukewarm heat from drivers side.

 

If the engine was running a while, they could both be hot. Did you actually measure the temp remote , or just feel them? But if the heater core were clogged on the one side, you would still lose heat there.

I just went through this type of issue on a Toyota that had been run with a low coolant level a few times (radiator had been replaced twice in 12,000 miles). The heater core was clogged and it took a bit of cleansing to make it 'warm and happy' again.

 

My 2014 crv had the exact same issue. Took it to the dealer and they did the clr flush and it was fixed. Cost was between $100-200. Never clogged again.

 

Thank ?you, for the info! I’m just going to take it to the dealer. Save me messing with it! That’s not very expensive.

Opps, my typing skills are not very good! Thank You, for the info.

 

I have had really good experience with my local dealer. When I called in they said yep we know what causes that and it will be this much. I use them for oil change and tire rotate, brake fluid flush and coolant flush. The cost for those services are $125 each which is not bad to me. I do my own trans and rear diff service. The charge $125 each for those also.

So, how much did the dealer quote for the hours-long flush? Inquiring minds want to know...

 

Joplin Missouri Honda dealer flush was a whipping $375, replace the blend door if that is the problem $140 labor plus part, which I don’t know the price of. Forgot to ask them! Seems really high to me..
