Hi I want to recahrge my a/c and was wondering if it was possible to do it with a recahrge kit and if so where the red anblue valves are located?

p.s. sorry about spelling

Before you go recharging your system are you sure it needs to be recharged? Just because its not cooling doesn't necessarily mean it needs to be charged.

However if you know for sure you need refrigerant the ports will be on the compressor inlet and outlet hoses near the compressor or near the accumulator; it all depends on what type of system you have (orifice tube or Expansion valve).
