92 AC Blows hot and cold
Greetings and salutations to all. Been gone about a year and am now back…good to be here.
Got a problem with my AC in the 92 LT1. The air blows cold for about 30 seconds then blows hot for about 10 seconds (hotter than ambient). While this is going on the fan remains at the same level although it sounds like the air is getting diverted (kinda like pressure is building up), but it isn’t coming out at the windshield or the feet. Have checked the freon level, it is good. The compressor in cycling as normal. There are no codes using the in-car up and down fan buttons or with an ALDL Killbrew analyzer. This happens with AUTO, RECIRC or BILEVEL. Additionally the green light under the AUTO button some times dims.
Background…Had an issue with lightening which took out the computer on my pickup, and some stuff in the house along with the ECM in the Vette. The ECM has since been replaced. It has been suggested that the ECC needs to be replaced. Any suggestions?
Signed…Sometimes warm in Florida
