So I own several GM cars and vans that I run as taxis. I have been repairing them myself for eleven years. I have never come across this issue. This is a Canadian Impala with 48,5000 kilometers on it.
I have replaced the compressor twice (failed units) as well as the condenser and expansion valve. The system has been flushed. Orifice replaced. Still not cold inside and no sweating either on the lines or dripping from the car. Pressures on an eighty degree day are approximately 35-40 low and 150-180 high side at 1500 rpm. The blend door works: no hot air and lots of flow. I added approximately 1.2 oz of oil as that is what I lost in the replacement. Also added app. 1.6 lbs of aftermarket 134 equivalent The question: is it possible that a dirt filled evaporator would allow air flow but because the whole system to run warmer than it should? I am really stumped. Thanks in advance.
have the same problem?
