AC help.
Hello all,
I did the AC diagnostic and came up with 2 codes: "eb1 227" and "eb1 416". Does anyone have any idea where I can decipher these?
My AC went from normal, to bad, to worse, to hot in the matter of about 2 weeks. #7 on the panel is reading approx 4-8 indicating possible low freon or at least that the pressure is low. So, I went to charge it only finding out that, according to the guage, I am good to go. I still have nothing but hot air through the vents and my AC compressor doesnt appear to be engaging. I am not sure if it is the compressor itself or the "command" signal TO the compressor.
Any help would be greatly appreciated.
John

Best I could find with a Google search. It looks like you may have a sensor going bad and the coolant circulation pump might be malfunction as well.
EB1 227 - Outside Temp indicator temp sensor (next to drivers side lower fog light. looks like a plastic cone in a metal holder behind black metal grill)
EB1 416 - Coolant circulation pump (in eng area lower passenger side next to headers. has some large hoses on it plastic part)
