Ok I searched this forum for other people having A/C problems like mine. I discovered how to get the diagnostic codes and I have two codes: 21 and 23. Now I have searched high and low for these codes to see what they mean. Can anyone help me out with what these codes mean.

Thanks.

Ok, I finally found the codes: 21 is because I checked it in the dark. Once I put the drop light to the sensor and checked it again, now I only have the 23 code. I checked the freon pressure and there is no freon in the system hence the pressure switch circuit (code 23). I am going to replace the Expansion valve and evap because while there was freon in the system it would only blow cold if it was dark out or in the shade and then turn hot, which is a expansion valve problem.
