Heat doesn't work in 96 Corolla
The fan works. The car temperature gauge is fine. The car is running
fine. But it blows only cold air. Is that a fuse? Or something else? Thanks |

While under the hood, have someone operate the heater control so you can identify the valve and check it out. Under dash work starts with a visual inspection. Having the fan operating on high will help determine if there is air blocked or leaking somewhere. You should be able to see the controls work. Dan (This account is not used for email.) |

You could have a vacuum leak, a disconnected hose or something else causing the temperature control within the heater box to malfunction. It could be a fuse. I would check them all. Good luck |
