Question about 2000 Toyota Avalon

1 Answer

Intermittent heater function

2000 Celica 1Z 4 cyl, auto--124,987, just replaced thermostat---not the problem--seems to work only when accelerating---does this car have a heater control valve or something similar? Does the P0446 code its putting out(among 4 others)related? I've never been able to find the source of my P0440 problem, any advice for this would be great too(yes I replaced the gas cap). thank you in advance for assistance

    post one question at a time if u ever want any advice, P0440 means there is a leak in the evaporative emission system or the control valve that pulls vacuum on the fuel tank is defective, or the pressure sensor on the fuel tank is defectve, any of these will generate P0440, as far as the heater goes u have air trapped in the cooling system, follow the manufacturers instructions to bleed it out.

EmWiz is correct. You have to remove the coolant overflow bottle, and RAISE IT UP to eliminate the trapped air in the system. The heater core is above the height of the radiator, and air tends to get trapped in the core. Raising the overflow bottle is the only way to purge the trapped air. Keep adding coolant to the overflow bottle until the bubbles disappear, and you have good heat at idle.

2002 toyota celica heater does not work


The thermostat should only restrict flow to the radiator.
If the heater system is working correctly, you should get flow from one of the heater hoses at all times.
Its possible you have air in the cooling system.

might need to bleed heating system / radiator. Air lock could stop flow of hot water. Check water colour in radiator - if brown and gungy there could be a build up of sludge so radiator flush required.
when dial / lever moved to turn heat on / off see if you can hear anything moving - there should be! Quite often when heater turned on or off small solid wires move valves that are visible under dash and on engine bay firewall. Watch these rods when someone is turning the heater from cold to hot and see if anything is sticking or loose

I have written a tip on this.
You may have a couple of problems. I would first replace the thermostat, and make sure you have the proper coolant(ant-freeze) level.

I have a 1987 toyota celica gt and the heater won't come on, the blower works but no heat, fuses are good but no heat


This problem is specific to the Gen4 Celica (86-89). Intermittent or no heat heat is caused by cracked solder joints in the Heater Control Panel. You need to remove the panel and re-solder the solder joints. When electrical continuity is broken, the panel defaults to the cold setting. If you go over a bump and it touches again, you may get hot. Hence, intermittent or no heat. We have the complete DIY fix posted at www.st162.net and it's free. Pic below shows the heater control points to re-solder.
