I am having a problem with heat in my 99 RX300. When I turn it on, it blows cold air. I can't seem to get the heat to come on...


Check coolant level, if that is acceptable,, then the problem may be a thermostat or the deflector mechanism inside the heater which should be checked by a qualified mechanic.

Low coolant light flashed stopped topped reservoir read label wrong saw dont fill engine damage can result....got back on road an check engine popped on pulled over wound up losing two or three litres out...


Your most likely problem is a bad head gasket.If you used the bleeders to remove the air from the vehicle and your are sure you got all the air out and you still have no heat and the coolant keeps coming out the over flow bottle.Then the head gasket is bad.Usually the rear head head.But I have also had the front head go bad.The best is to replace both gaskets.You should also have the heads checked to make sure they are not warped if the engine ran hot.Hope this helps.Good luck.Let me know if you have anymore questions.

My heat is blowing cold air.


Could be a number of issues:
Low Engine Coolant
Thermostat,
HVAC controls,
or Heatercore.

Check in this order:
Make sure your engine coolant is not low!

Does your engine heat up to the proper temperature? If not, change the thermostat.

To check heatercore try this:
Keep your air turned off, after the car's engine is heated up nicely, turn the heat on and see if you get some heat for a short while. If this happens, your heater core is plugged.

Hopefully one of these help fix the problem for you as diagnosing the controls is harder.

My coolant fan only works with a/c on, but not heat car running hot


Have the coolant temp. sensor check out, sit by thermostat housing.If you unplug it and fan comes on, more then likely bad sensor.

Heater doesn't work with my 2000 Lexus RX 300. a/c works fine but no heat even when I set the temp to 75 or higher


Possible air bubble trapped in the HVAC unit so the heat from the engine is not getting to the heat exchanger

Not enough heat coming out


Hi

Sounds like a flap problem on heater unit.

Get your head under the dash and check for movement, when you operate temp control hot to cold.

Good Luck !
