Engine Warning + AC off
Dear Hummer friends,
Trouble with my brandnew Hummer H3 , since today "Engine Warning " light and in the Display the words "AC Off ". any help ?? Thank´s to all Franz |
Sounds like it was overheating. Was the temp gauge in the normal range?
|
everything in normal range, drives as before
|
Did it not go in "limp" mode and not allow you to accelerate?
If you are sure it did not overheat sounds like a sensor problem. See your dealer. If it displays that and shuts down the ac and goes in limp mode that is to protect the engine. It will shut down some cylinders from firing and only pump air to cool it down. Better get it checked under warranty. |
Hi,
the car did not go into "Limp" mode, everything seems normal. I think i got he conclusion: the car is equipped with a auxiliary heating system, if that thing is turned on in winter approximatly 30 min prior starting, the sensors get false readings, the problem ist that the engine warning keeps on glowing, even if the situation is cold again. greetings from Germany |
