Thanks for the update.....So the replacement TXV was bad and you put in the original and all worked well? Yes, that seems to solve the problem of bad cooling at idle. On the highway or when driving in general, the evaporator now get down to freezing temperature and the clutch disengages for a few s...

So, after some fiddling around I believe that I had a bad txv that I replaced previously when my evaporator went bad, after replacing the original txv and charging the system with appropriate amount, ac blows 43°-49° in 110°+ ambient.

Just an update in case someone had the same issue I had.

Therefore, I don't think you'll find anyone on this Forum who will offer advice about such a conversion beyond what I've already said. Well, I live in Saudi Arabia and it is legally allowed here a...

I am no help on your situation, I am just amazed at the info you can get from the RAM with that app. That's a cool app. I took a screenshot of the alfaobd app monitoring the hvac module https://i.ibb.co/7j736PN/Screenshot-Alfa-OBD.jpg Yeah, the technology we have today is great, scary and frustrati...

Just wanted to add another question, will running my ac system while undercharged hurt anything? When I put the full charge of refrigerant as per the hood sticker, the pressures at idle were 40-42 low and about 200 high (need to verify that again), but when undercharged low side reads 30 low 180 hig...

Hi there, Just joined the forum :D I recently changed the variable displacement compressor in my Ram 1500 to a fixed displacement compressor, the original was 7sbh17c denso that I have replaced with 10sre18c valeo. The valeo unit I believe is the same as the oem ones for the 2009-2010 year for the s...
