TO HAVE BEEN OVERCHARGED WITH R134.THEN I REPLACED DASHBOARD AUTOMATIC CONTROLS THAT DID NOTHING. MECHANIC SAID COMPRESSOR WAS NOISY BUT
IT SHOULD STILL WORK,HE SAID IT COULD BE IN THE
CONTROLS,HENCE THE CONTROL REPLACEMENT.
,I HEARD THERE IS A AC/HEATER PROGRAMMER
AC DELCO PART #15-71774 ,COULD THIS BE MY PROBLEM? ALSO HOW DO YOU CHECK AND WHERE ARE THE
AC VACUUM LINES? PLEASE ADVISE. THANKYOU.


Answer
Could be loss of vacuum to the programmer and or faulty vacuum lines.

The programmer is located up under the dash on the passengers side about knee level.
