T Sport AC unit

Recommended Posts

Recently bought a T sport 2002. Full Toyota service history . Came to put the heaters on tonight and can’t seem to get it out of AC mode . Even when it says hot still blowing cold .  When it’s turned off warm air does trickle through . Is it something I’m missing or is it a fault ? 

If a fault is there a common fix or anything 🙂

Hi,

Could be several causes, but suggest you look under the dash, driver side, where the servo motor operate the air control flap, seems the plastic linkages/gears can break.

If you look under while pressing the temperature button across its full range, you should see  the motor operate.

Have heard tales were the flap actually slips on it shaft, but thats a major a/c out job.

It’s the light that’s I can’t get off . It’s always on when selecting anything to do with heating or temp etc

Hi,

Could be that switch has gone faulty or that whole  heating control unit has a problem ? seems it has its own involved circuitry.

You could  try running its basic diagnostic, below,  that may or not work, but also it might serve as a Reset to clear thing if its electronically stuck on that switch.

You could also try disconnecting the Battery for a few mins to see if that clears things.

Never had that module out , so not much more I could add ..

Unfortunate that the AC doesn't work. I hate when that happens.

    1. 1. If you were to consider buying a Hybrid model over 5 years old, would you be worried about the reliability of the Hybrid system?


      • Not really as Hybrid systems are always reliable
      • Not if it had a Manufacturers Warranty on the Hybrid system
      • I would not buy a Hybrid model over 5 years old
