Thanks for using JA
This means that the system is very low or empty of freon. you need to find the leak and repair it. a leak is found by charging the system and adding dye to it or using a freon sniffer. this is a detailed job and requires strong knowledge of the system.
So I replaced the switch and, sure enough, the compressor short cycles, consistent with low freon. I will have it checked out! Thanks.
I got some leak detector, and cannot identify any leaks so far. I did notice the line running between the evaporator and the radiator area is cold and sweating, and the small line is hot, but the compressor still short cycles and no cool air in the cabin.
the majority of leaks are around connection points and o rings, but bi parts like the condenser, evaporator also leak. charge the system with a kit from walmart or any other parts store and run it once it runs a leak should be easy to detect.
So, you don't think the cold line has any bearing here? it seems like, if the system is cooling, there must be some coolant in the system? is it just not enough to cool the air coming out of the vents?
I just recently purchased a 2004 Tahoe with 155000 miles
