Problem with my aircondition system
I have very basic english but i hope it will be readable.
I drive a mb s320 99 and it have now rolled 21 0000 km. The only problem i have had with the car is when i go out for a drive that is longer than aprox 40 min the aircondition system stops to function corecctly.
Just before it happens you have the fan on fullspeed or auto to keep the car warm and then you pass the magic 40 min mark and the fans still goes but the airflow is choked. You can adjust the fans and hearing them going but the air does not come in to the car it gets blocked on the way. You can adjust everything as normal but the flow is heavely choked and you will only be able to get a little air through if you have the fan on full speed.
If i stop the car for 10-15 min it will work for aprox another 20 min then the same thing happens.
I got the car check with the mercedes store computer system and they could not find anything.
I hope i got you to understand the problem, if you need any other information to solve the problem just tell me.
I hope you can help me!
