Check that the switch that moves from cool to hot (Is like a sliding switch on a 1990 Corolla I think) is actually opening the vent that controls flow of hot air
heat and a heavy hammer the larger the better
Check the heat shield on the catalytic converter
try changing out the heater core or the therma stat may be bad
The heater isn't an extra unit, it is simply pulling heat from the engine and blowing it into the cab. If the engine is not hot the heat will seem like it is not working. If the heat is not working after the engine has warmed up, you may have a fan that doesn't work, or a clogged vent.
Sorry bad news Your heater core has a leak
The exhaust manifold on a 1998 Toyota Corolla is located on the engine, attached to the cylinder head. It collects exhaust gases from the engine's cylinders and directs them to the exhaust system. Typically, it is situated on the side of the engine facing the firewall, making it accessible from the engine bay. To reach it, you may need to remove other components, such as the heat shield or intake manifold, depending on the specific repairs being undertaken.
You may be low on coolant. Check the reservoir and the radiator, if it is empty check for leaks in the system. If it is full you may have a stuck open thermostat causing no heat.
it's in the down pipe coming from your exhaust manifold. you will have to remove the heat shield from the exhaust manifold to access it
To replace the starter in a 1982 Toyota Tercel Corolla, first disconnect the negative battery terminal to ensure safety. Then, locate the starter beneath the engine; remove any necessary components for access, such as the intake manifold or heat shield. Unbolt the starter from its mounting and disconnect the wiring harness. Install the new starter by reversing the steps, ensuring all connections are secure before reconnecting the battery.
I have the same problem I am ready to jack the chrysler up and install a Toyota underneath it
Heat is coming from the engine.
There is a 'lock' button on the drivers door. By the up/down switches. The driver is in control of the vehicle and I think it's right that the driver have that control. I think the driver should have a lock on the climate, heat & a/c also
