2002 Mercedes Benz C240 Base 6 Cyl 2.6L
Sometimes my ac cools sometimes it doesn't ,especially during hot weather what could be the problem?
I recently just had my compressor changed everything was fine for the first six months until recently
Had the same problem.....need to add air conditioning fluid to your system....Go to AutoZone and explain problem....they have the pressurized coolant fluid to add to your system...Comes in a can ....about $20....Can do it yourself.....or (I have a friend who is more mechanically inclined than I)...have a mechanic do it....not a big job...but a Cold world of difference !!....Hope this helps
