hi guys...before i say my problem i wanted to say sorry about the technical language that i use.

.because i am very newer in cars general tech issues..but i think i feel pretty lucky that i started my driving life with oldsmobile in a some european country
our problem is with air conditioning....not a manual one..it gives hot perfectly but it stopped to give cold by the end of the summer ...what might be the problem?we could not take her into service yet...i want just figure the problem before we take to service.. and another problem what can we do about speakers?(all orijinal audio equipment that came with olds) sometimes stratchy but not everytime..in here the problem is wires or speakers?
i think stratching audio is common problem that i observed from forum....
and last one is about front bumper... there is little crack at the right corner of the front bumper...where can i order a bumper cheaply?ebay or something ?...or is there a reliable(and cheap?oldsmobile part site that i give my order to istanbul /turkey.....best regards to all olds users..
