Only cold air in passenger site

[Lexter]

Hello everybody!

My IS250 only blows cold air on passenger site and on driver side  warm, not hot. It happens after removing the Battery for an hour. Is there a trick to reset all servo-motors or is something else be broken?

[Brechin Slate]

Silly question but is your A/C set to Dual?

[Lexter]

No, in both modes only cold.

Hey,

Strange if it only happens after removing the Battery.  Is it the same the rest of the time?

It sounds like the servo motor may have failed.  Unfortunately, the only way to diagnose this (other than replacement) is to hook up the TechStream software and check the Pulse value.

Also - check the coolant level

Is there a "gurgling" sound in the cabin by the drivers foot well when the cars running. If so it could indicate the coolant is low and needs a top up.

There is no gurgeling...but how can i bring out all the air of the cooling-system?

Which adapter is working with TechStream-Software?

I've got software and tester...how can I check the pulse value? It allways show error: aircondition-ECU not availible...but other ECUs ok, so adapter works
