Bill560 Posted June 26, 2006 Share Posted June 26, 2006 My 95 has some AC problems. I get a code 21 for starters. Now the problem! Sometimes it is nice and cold and working correctly! Other times it works for about ten minutes and then starts blowing warm to hot air! The 21 code is for the Solar Sensor on the dash! Has anyone had this go bad? I have had the system evac'ed and refilled twice and no leaks were found! Thanks Quote Link to comment Share on other sites More sharing options...
SKperformance Posted June 26, 2006 Share Posted June 26, 2006 The solar sensor only controls the flow of air to vents or floor not temp. It is not registering any code if you get 21 . It is too dark when you checked it so the sensor shows up Quote Link to comment Share on other sites More sharing options...
