Hi evryone,

just bought an 03 Suburban LT with automatic aircon.

The aircon is either blowing freezing air (on anytemperature below 90 degrees on the display) or hot air (on 90 degrees or above). Therea appears to beno control over the temperature.

I'm geussing this is soomething to do with the air temperature sensors (as we are getting heating and cooling) but could anyone help with diagnosis please?
