The AC was blowing about 50-54 degrees out of the vents and the compressor was constantly cycling. I replaced the compressor, condensor and expansion valve. Then re-charged the system. Now it gets to around 48-50 at best. My 100 series and a GMC Yukon I have all get down to 40-42 according to the same guage I use on the 4Runner. I took it in to a shop and they went over the entire system and said everything is good. I have heard from a few people that the 4Runner AC systems are weak. Does anyone else have this issue with any year 4Runner?
