1) Get the stored error codes out of the ECM; that'll tell you what your flashing Check Engine light is trying to tell you about
2) The blinking temperature digits on your HVAC panel (which presumably stop blinking after the first two minutes of driving) are telling you that the automatic climate control system has detected a fault of some kind. It'* most likely low on Freon, as someone else said. There is a separate procedure for getting its own error code (separate controller not related to the engine or Check Engine light), but if the system seems to be working okay other than maybe not blowing cold A/C (which it also uses for windshield defogging), low Freon is probably your only problem there.
