Question about 2000 Toyota Camry
I don't know why the inside of my Toyota Camry is so hot, the heater is not on and sometimes I just drive small distances however is most of the time really hot.
I live in LA so I don't have need for the heater 95% of the time is there any way to disconnect it?
The heater works from hot water from the engine. The flow of hot water into the heater is controlled by the climate control computer. If this is not functioning properly it can be heating even if you have switched it off. Fixing the climate control system may be complex. The flow of water is controlled by valves which may be jammed open causing it to heat all the time. These are under the dash so to fix them you will have to dismantle most of the facia. This can be done but you may battle to find all the concealed screws and clips. If you try it take a careful note of where everything fits so you can put it back later.
To disconnect the heater completely you have to locate the rubber hoses that carry the hot water from the engine into passenger compartment. There will be 2 hoses, one carrying the water in and one carrying it back into the engine after it has circulated through the heater. You can stop the flow in 2 ways, as follows:
1 Disconnect both the in and the out hoses from their respective manifolds, buy a piece of rubber hosing the same size from your friendly auto parts store with 2 hose clamps and fit it between the in and out manifolds. This will take your heater out of circuit completely.
2 Put a clamp on the "In" hose (this will be the hose connected to the engine at the front near the water pump). You can do this with a "C" clamp that you can buy at any hardware store. This will stop the water flowing throough the radiator.
Good luck and stay cool.
