I'm having a problem installing orifice tube in condenser when I checked it to see how much trash was on it it had a white one like they used in the 12 systems installed at evap . This one I the black and white one installed at condenser outlet it will not go all the way in condenser the part that sucks out will not go in evap line never had a problem with these is there some one that has seen this before? The condenser looks ok. Just like it hits a stop it has a crimped spot but it does not look like it is getting to the crimp. If I need to post pics I'll go to shop tomorrow and take some to post .

OTs that go in condensers are black- the ten "window" screen goes in first- that is the inlet of OT- works every time if done right-- the white one you found was the wrong one probably installed backwards..

-------------------------
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
