Air Conditioning problem
2003 Chevy Silverado V8 Four Wheel Drive Automatic 65,000 miles
my ac seems to be working ok.I get it to about 42-44 degrees on setting 2, when I turn it up to setting 5 it seems to loose is coolness. Ive been using a candy themometer to test it and it just doesnt seem to get cold enough. My wifes grand caravan get to about 36 degrees. It takes my truck a good amount of time to reach 42-45 degrees. How cold should it get and how do I locate the low pressure side so I can recharge it if needed?What else could cause it not to get colder?
Low side service port on accumulator see diagram when full reading should be 35 psi window down blower on high.
Start with guage readings if good do not add freon possible blend door malfunction or other problem.
Hope this helps
