IHA 97 Malibu 2.4L. The AC is starting to run cool instead of cold. it has not been services in about three years. Are those kits at parts stores which flush, lubricate and recharge with R134a worth it? They run about $30 whereas a full service will cost in excess of $100.

 

take it to a dealer.......all the ones I have seen done by a garage or someone in their yard end up at the dealer anyhow to fix it after someone screws something up....it proly just needs recharged.
