Hello and welcome back to justanswer.com

 

Your low side pressure is slightly high but if the compressor is operating and the a/c lines going into the evaporator are cold then you may have a problem with the temperature blend door actuator. If you do not feel a difference in the outlet air temp when moving from hot to cold then run the self teat on the EATC. Press and hold the OFF and FLOOR buttons at the same time then release both and hit the AUTO button. At the end of the test if a code 022, 024, or 025 are displayed then the motor is the most likely cause.

Lincoln Mechanic: Richard, ASE Certified Technician replied 8 years ago
Try doing the test again with the ignition ON. Press and hold the OFF and FLOOR at the same time then release both and hit the AUTO. You will see lines scrolling on the screen then fault codes will be stored. If there are no codes you will see what looks like 88.

Sorry for the delay. If the a/c system is working and those a/c lines are cold then you may have a problem with the blend door even with no codes. the blend door actuator will need to be removed to check the door.
