andre Posted July 5, 2006 Share Posted July 5, 2006 hello guys, I'm not getting too much of a cold air coming from my a/c, so I have checked codes for a/c today and came up with code 21 flashing - can any one explain what does it mean in plain english? I'm planing next week to recharge a/c gas -will that clear the code 21? Thanks for urgent reply's andre Quote Link to comment Share on other sites More sharing options...
SKperformance Posted July 5, 2006 Share Posted July 5, 2006 It means nothing . The solar sensor reads daylight and adjusts the fan to blow to the vents more than the floor to compensate for the sun on your face. I was sure i added this to the tutorial.

Hello SK so why is it blinking? regs andre Quote Link to comment Share on other sites More sharing options...
SKperformance Posted July 6, 2006 Share Posted July 6, 2006 The solar sensor is not blinking. Try and explain things as much and in as much detail as possible. I am glad you found the tutorial on the hvac system but a flashing a/c light is from compressor lock up. You either have a blockage , bad compressor or expansion valve. All 3 have easy to search answers on replacing. Quote Link to comment Share on other sites More sharing options...
