Heat issues on passenger side

[super2kc]

2005 4runner LTD V8
For a long time I had no heat on passenger side, freezing cold only... especially on really cold days.
I checked and had electronic dampers replaced - still no heat.
Flushed the heater core with CLR - helped a bit for a month then back to cold again.
All other possibilities were checked, coolant level, Thermostat, all electronic HVAC controls functioning correctly.
Stealership of course being the retarded pieces of @!$*&T that they are, wanted to charge me $2500 for a new heater core. as you can easily tell...I have ZERO respect for dealerships.
SOLUTION at last...
Went to Mr.Lube here in Ottawa, buddy pulled my heater core lines and blasted the heater core with with high pressure hot water into the bottom core line.
Did a rad flush for good measure.
Heat is back to like a brand new truck again.
Just thought I would share.

Assuming you didn't have heat on the drivers side as well?

HI. My 2004 has no heat on the passenger side as well. It started last winter but forgot until just now. Driver's side heat is perfect. ANY further input to this problem?

Thanks
