500 SL 1997 air conditioning get on faulty mode
Hello All! ,
During the weekend after the car has a long time w\o starting , but with the battery charged on a intelligent charger , I observed a kind of peak voltage afer the first engine runing and after that ( the power window stay a few moment w\o work),then I observed the a\c system do not work when I touch the panel buttons .the only operation button which get light on when press the button is the defrost one .
The a\c panel is fully off and no response when touching any button . I just observed both red lights are on in two buttons of air cold and hot air in middle positon of central vents .
I ´ve checked the fuses and are ok on fuse box .
any tip to reset the system?
What kind of procedure can I do w\o star electronic tool?
can you guys help me on that ?
thanks in advance
Alfredo

system fixed by himself
Hello all,
my surprise after some frustrate tentatives to restart the A/C , cheking fuses and disconnect the battery , the air conditioning restart to normal funcition after a few miles driving on road conditions by himself w/o any further action.
So now is pray to the system continues to a normal condition next time I start the car .
Regards,
Alfredo
