Hi, I' m Chad. Welcome to JustAnswer. I' m reviewing your question now, and I will be post back with your reply ASAP

Expert:  Chad Farhat replied 3 months ago.

what is the mileage on the vehicle ?

is there a check engine light on ?

do you have a diagnostic scanner that can read live date like the ECT temp sensor ?

1- ECT sensor will be # ***** in that diagram

if this sensor is malfunctioning that will cause the 0 in the display

2- now as far as a/c want come on , did you check all the fuses ,and the a/c relay ?

is not coming because you leaked Freon and it quits because the system has less than 25 % or all was working fine and suddenly quit ?

please let me know

Thank You
