    Having this issue with my '05 Silverado


    Trying to figure which exact PT# I need ?? 604-106 or 604-112 ?? 604-121 ??


    Have the base LS, manual NON digital A/C. NON center console setup


    1-2 times a day, My A/C goes from cold to hot, So I have to shut off truck and restart it for it to reset. Only thing is both driver and pass vents stay same temp ????


    My autozone manager buddy says its 604-106 but I want to make sure before tearing down trim pieces taking things apart

    Thanks in advance

    Forgot to say that #4 #5 fan setting doesn't work either

    Just only 1, 2, 3 fan settings

    YOU'LL HAVE TWO OF THESES, ONE ON TOP OF THE A/C CASE AND ONE ON THE BOTTOM ON THE PASSENGER SIDE. BOTH USE THE SAME PART #
