I have a 95 Suburban that blows cold air. (350 5.7 engine) I suspected low coolant level & found that my radiator wasn't 100% full & my water pump had a small leak. I replaced the water pump, both upper & lower hoses & the tstat (195 degrees) After the repairs the temp gage on the dash varies between 175-210 & the air from the vents is only slightly warm. 95-100 degrees. Is a 195 tstat the correct temperature? Could there still be an air pocket somewhere? How can I troubleshoot this further? The controls all seem to be working properly. What else can I check or verify? Thanks in advance, Benjamin

I'm seeing a lot more used car ads for cars that are less than 10 years old with normal mileage that say "a/c compressor replaced" or "a/c not working" or similar language to indicate problems with the a/c system. Are a/c problems becoming more common on cars these days? Could it be the new R134a refrigerant? I've read that R134 A/C systems in most cars after about 5 years have high failure rates because they run at a higher pressure and are not as cold as the old R12. It seems like more domestic makes have problems than imports regarding air conditioning, from the ads I read. I remember driving 80's GM cars with R12 that would freeze you out and last a long time. What are some late model cars with good or problematic air conditioning? I'm basically after a reliable low mileage peppy/good torque for around town midsize sub $3000 car with an ice cold A/C system. Should I stick to cars with the old R12 system or ones with brand new a/c systems installed? I've usually found good luck with 1986-1991 GM A-Body (Pontiac 6000, Olds Ciera, Buick Century) and 1986-1991 H-Body cars like the Olds 88 and Buick Lesabre. Thanks in advance for your advice/opinions.
