    Why does my van blow cold air and sometimes overheat
    I changed the thermostat and flushed the radiator its not the heater coil cuz there's no coolant on the floor bored and when I have on the defrost nothing blows on the windshield. Any ideas of what it can be?

      The blend door actuator is a servo responsible for controlling the mix of warm air from the heater core and cool air from the A/C and outside. If it malfunctions, your climate control system may not respond properly when you change the temperature on the climate control system.

      Both the manual and the automatic systems use this servo to control the blend door. If your ATC system fails to automatically change temp, this is also an indicator that the servo has failed.

      The Mode Door Actuator controls the direction of airflow. It selects which way air flows through the different ducts. If your climate control system has lost the ability to control which vents the air comes out of, the MDA has probably failed. Both the ATC and MTC systems use this device.

      Both failures can be seen by the climate control system's integrated diagnostics system.

    I have had multiple ignition module failures over the last two years. I am looking for the root cause of these failures
    In the most recent repairs, both the module and three coils have been replaced. The 5 module failures have all occurred following an engine replacement. What might be causing the problem? A bad ground connection? Where? A conductive grease was used when ...

      If the ignition module has failed more than once, it may be due to a bad ignition coil. Internal arcing or shorts in a coil can overload and damage the circuitry inside the ignition module.

    2002 Buick Rendevous has new battery, but after going a few miles it will not start again. Engine has to cool
    completely to start again. Could it be a clogged fuel line or bad distributor?

      It could be that with 1/4 tank of fuel & on a hill the computer sees a low
      fuel load & that may be your only issue

      I say that with experience on ford & lincoln vehicles & their system strategy
      Not familiar with GM CAN Vehicles from 2004 on

      I would try it with a full fuel tank to confirm that theory as it is a little weak

      Check fuel pressure at the motor after it has been sitting for awhile to see
      if the fuel pump or module holds pressure
