Just got done doing a gt to lx swap but left the lx ac system right in the car thinking it would function as long as I can charge it up and turn it on. Apparently not the case. I don't know if there are any differences between the gt ac system and the lx ecat ac system. I've scoured the forums for a lead but I'm not getting anything definitive. Please help.... I've got 12v on the 2 green and white wires coming into the ac relay. Also 12v at the solid green pressure switch wire. If I ground the green wire, I get a complete circuit, ac relay clicks and clutch engages. If I jump the connector, I get nothing. When ac switch is on and blower lever is on, the main rad fan turns on, but not the condenser fan. If I jump the switch at the reciever, the condenser fan will turn on. Ive done the retrofit and added about 2 12oz cans of refrigerant, an anout 2-3oz of oil. Not accurately measured, I know, but I should get something. If the compressor is supplied direct voltage, it will turn on and vents will blow cold. Just won't turn on from inside the car. I've swapped the front harness, main harness, dash harness and ecu to run the f2t and mtx. Anybody have any ideas on what I'm missing or didn't do right? I'll be surprised if I get a reply back, but any input is super appreciated.
