No heat on driver side

[GTyankee]

I have always checked to see if the Motorcity Mechanic has done a video on some thing that i have wondered about, every one else is a close second best

Flushed the heater core and I now have very hot heat on both sides!

For any others with the same issue, here’s what I did. Disconnect the heater core lines at the water pump, directed one to a drain pan and poured water into the other, then blew it threw with an air compressor in short spurts. Did that several times both ways (didn’t know which was in and out lol), then with both hoses held up as high as possible I poured in CLR (calcium, lime, rust remover for those who don’t know) and let it sit in there for about 30 minutes. Then drained that out and rinsed several times with distilled water blowing it through with the air compressor. Finally I reversed the hoses when reconnecting for a long term back flush and after dealing with some air bubbles it’s nice and toasty!

What a great resolve, I am having the same issue and already did a flush/backflush but did not try the CLR - going to give it another go with your method before resorting to pulling the dash/heater core change. cheers
