The heater core is on the passenger side under the dash within the heater airflow contoller box. If you had Xray vision and could look straight through the glovebox, then you would see it. The heater control vale for the water flow is on the passenger side top of the engine near the firewall. It will have a domed top with a vacuum line to it and it is placed into the heater core supply hose.

2000 chevy silverado not blowing hot air


1: not enough liquid in the system (air in the heater core)
2: inoperative heater valve not allowing hot liquid into the core
3: hot/cold blend door in the heater box stuck on cold
4: clogged heater core
A clogged heater core will have one hot hose and one significantly cooler hose at the firewall connection; easily tested by hand. a good core will have both hoses very hot to the touch when the heater is on full blast.
Make sure that the system is full and at operating temperature, and the heater controls set on full heat. Feel the hoses at the firewall; if they are both too hot to touch then the problem is in the heater box or controls.

The heat in my truck isn't very hot. the truck doesn't run hot, so i'm not sure if it could be the thermostat, or possibly the heater core. I have a 2000 Chevy Silverado Z71 with the 5.3 V8.


Try replacing the thermostat for a couple bucks and a twenty minute fix. You could also try unhooking the heater hoses to check if there is crud holding back the water, which you can also check the temperature of. Before you do anything, get a good manual like a Chilton or Haynes for your truck that will guide you through the troubleshooting and the repair if needed.

I have a 2000 Chevy Silverado pickup, and the heater will not blow hot air. I replaced the thermostat, and nothing changed. The radiator was flushed and filled in the last two months as well. I have all...


once truck is warm check both heater core hoses to make sure they are both warm if not then check the cold water valve could be stuck shut not allowing coolant to travel in to heater core.

I have a heater core leak on my 2000 chevy silverado V6, is there an easy fix?


You can bypass the heater core, you just wont have heat anymore. On the firewall of the truck, behind the engine, you will see 2 rubber heater hoses that go into the firewall. They attach to the heater core. Disconnect them and get a plastic connector, and connect the 2 hoses together with clamps to hold them down. This will stop coolant from going into the heater core, and no more leak.

No heat !!! just blows cold air. I think it might be the thermostat. Where is that located on a 1999 Silverado? It is the small V8


could be the heater core valve, check the cable that opens and closes the water valve to the heater core.

check also the setting of the temperature level. it could still be set to cold.

wait for a few minutes for the water to heat up on the radiator. you could have tested it after you start the car and the engine is still cold.

tnx 4 using fixya,
