I'm hoping someone can help a new member out!
I have a 2012 Ram 1500 with the 5.7 liter hemi that had to have the evaporator changed out. The shop I used didn't have a sophisticated machine and charged it as best as they could. Turns out that it was 9 ounces low. I had a professional shop vacuum it down for four hours, and it held the vacuum flawlessly for 2 hours.
They then charged it with the exact amount with a digital machine and it works amazing now!....but only at idle.
When I drive, it works, but not as well as it does at idle. Essentially, when under a load the compressor doesn't stay on as long as it should and I can feel the air get a bit warmer and it smells a bit stale, if that makes sense?
I was wondering if anyone has had this issue, and has found a solution? My initial thought is that the a/c pressure transducer is marginal, and should be replaced, but that is a complete shot in the dark.
My other thought is that the mounted orifice tube is partially blocked, or the same scenario with the expansion valve.
Any and all help is appreciated!
Thanks in advance.
