Chevrolet Repair: A/C, chevy astro, compreser

Question
I just replace my a/c compreser on my 1995 Chevy Astro wich has dual evaperater.  I replace the orafes thats front of the truck, but I can't fine the second one.  It's there a second orafes,becouse I'm not getting any cold air out the back?

Answer
HI OSCAR, YOU WILL FIND THE REAR FILTER OR ORFICE SCREEN IN THE HIGH SIDE LINE JUST BEFORE GOING INTO THE EVAPORATOR. LOOK FOR 3 LITTLE DIMPLES IN THE LINE,, THAT IS WHERE THE ORFICE TUBE IS SET. YOU WILL NEED TO REMOVE THE INTERIOR PANELS AROUND IT OR POSSIBLY YOU MAYBE ABLE TO GAIN ACCESS TO IT UNDER THE VAN IF THE LINES ARE FED FROM THE BOTTOM UP..LOOK UNDER THE VAN BEFORE REMOVING ANY PANELS IN THE REAR FIRST. I HAVE SEEN THEM FED BOTH WAYS. AN ASNWER TO YOUR QUESTION,, IT IS POSSIBLE THAT THIS ORFICE IS PLUGGED FROM WHAT I WILL ASSUME IS COMPRESSOR FILINGS ??? WAS THE FRONT ONE PLUGGED ??? IF SO THE REAR IS ALSO PLUGGED. AFTER REPLACING THESE TUBES YOU CAN ALSO PURCHASE A FILTER SCREEN THAT GOES INTO THE SUCTION SIDE OF THE COMPRESSOR LINE WHERE THE LINE GOES INTO THE COMPRESSOR TO STOP ANY DEBRIS FROM GETTING INTO THE NEW COMPRESSOR AND DESTROYING IT !!! WE HAVE SEEN THIS MANY TIMES !!! YOU MAY WANT TO FLUSH THESE LINES OUT FIRST WITH COMPRESSED AIR AFTER REMOVING THE DRIER LINES FROM THE SYSTEM.. I HOPE THIS HELPS YOU,IF YOU NEED MORE INFO,GET BACK TO ME..IF YOU ARE FINISHED WITH ME, WOULD YOU MIND RATING MY ANSWER WHEN YOU LEAVE THIS SITE..THANK YOU,,,TOM...
