    1998 Eldorado ACM B1348 code

    Hi there.

    I am getting this code and have tried clearing it to no avail. I have tried it on multiple temp settings as well and had no luck.

    Here's the kicker, though. The system was blowing cold air 24-36 hours ago as it is supposed to when set on a cool temperature. The compressor isn't locked, and I haven't had any evidence of a leak. In fact I just topped off the system with a gauge connected to ensure I didn't put too much in.

    I'm thinking it's more of a sensor issue than mechanical.

    Any ideas would be helpful.

    Thanks,
    Pose

    Also, two other things: The accumulator is hot to the touch and when I put my gauge on the accumulator, it reads 15 psi. I don't know if that is important in the diagnosis or not.

    Must be a big leak for that kind of drastic difference. Looks like I need some leak finder.

    Thanks
