Air Conditioning
 

Hello.
I have some problems with my 2005 S40 T5 air conditioning. When temperature outside goes to about 30C it will start working for about 5 minutes and then will blow outside air only untill I stop engine to cool down and will start the same patern. Just today our temp went down to 24C and it worked but did not stop cooling at all.
Last week I spent $500 on fuel pressure sensor replacement and would like to avoid another large bill at dealership.
Does anybody have a sugestions?
Thanks a lot for any help.
