Hi

 

I have a strange problem with my Tspirit 2006 Auto,  the blower on the heater works fine at the first 5 settings if I increase any more the fan stops and I have to switch blower off then start on speed 1 and it runs no problem up to 5 again this happens hot or cold settings has anyone had this problem any help would be great

Thanks Adrian

Yet to see any detailed diagrams  of the later digital type of heating controls.

If it was the older model I would say the blower resistor pack was faulty but on the digital type no idea if there is one, or if its totally electronically controlled.

Toyota do have an online service where  for a small fee you can get service diagram details etc, so if you can see the actual circuit you have a better chance of locating the fault.
