    Hello Guys,

    New to this forum.

    I have a 2011 Cascadia DD15 that have an A/C issue.

    It had a leak on the evaporator, we replaced it and charged it back with almost 5 lbs of freon and test it for leaks, but now the compressor doesn’t want to kick in.

    I reset the a/c but didn’t work, the compressor did work when i connected the power directly from alternator.

    Any advice on what could it be?

    Thank you!

    A temp sensor on the evap. can stop a/c comp from coming on, the work you had done may have left a wire not reconnected on temp control sensor?

    Hi, thank you for the response. Like you mention it was the connector from the sensor that got disconnected when it was assemble back.

    A/C running good now.
