Message: [QUOTE="robby830, post: 1545912, member: 32748"] Hi, new 6.0 PSD Excursion owner of just a few months and new to the forums. Having a some AC issues hoping you guys can help with. AC didn’t feel cold at times when I bought it. The vacuum pump went out and when I replaced it, seemed to have helped for a bit, but summer heat hadn’t arrived yet to really test it. Then on a recent trip, AC started blowing warm air when at idle. I put gauges on it and low pressure was around 60 and high pressure over 400! I sprayed water on the condenser and the high pressure would drop around 225. Turned out to be the fan clutch. Replaced it with 7.3 version with adapter and thought AC issue was solved. Now with summer heat it’s not feeling that cold. Measured temperature in the cab and it varies between 55-70. I evacuated the system and checked the orifice tube. It had some yellow rubbery debris in it. I replaced the orifice and accumulator first to see if it changed anything. Still getting the same cabin temp but reading at the gauges seem normal (60/225). I went ahead and replaced condenser, compressor, accumulator, orifice tube, front evaporator and expansion valve. I flushed the lines and the rear evaporator. There was some metal debris that came out. I vacuumed the system for a couple of hours and recharged it with 68 ounces of refrigerant. I’m still getting same readings with the gauges. Also notice that cab temperature climbs between 60-70 when the rear AC is on. With just front AC on, it’s between 50-60. Shouldn’t it be around 40 though? Also, is it normal for the cab temp to rise when rear AC is on? Outside temp is currently between 80-90 in South Florida Thanks in advance! Robby Sent from my iPhone using Tapatalk [/QUOTE]
