cold heat in georgia

1996 toyota corrolla, water pump replaced, right away heater stopped working. thermostat replaced, still cold. mechanic says heater core blocked. i think probably gasket loosened by pump replacement, no biggie, not looking to place blame, same stuff happens in my trade. do i have to replace the core? only problem is getting to it, or can a radiator guy clean/roto-root it out?

Try removing both lines and attatch a water hose on the return side to see if you can back-flush the blockage out of it. Sometimes changing the direction of flow is all it takes to flush out a blockage.

Warm up the car. Turn on the heat. Feel the heater hoses. If they are hot, the problem is the vent door inside the car.

If the hoses aren't hot, there's a cooling system issue (bad thermostat, etc).
