88-91 92 93 94 95 96 GMC CHEVY SUBURBAN SILVERADO CLIMATE CONTROL REAR DEFROST

hey guys Jimmy here again and I am here in my 1995 GMC Suburban and having a problem that I'm sure a lot of you guys out there are having also and it's with the air conditioning control module see what's happening is as I drive along and the knob on the fan speed is turned off which therefore should be turning off the entire air conditioning basically I'm having this issue where no matter whether the recirculation button is pressed or not and the AC button is pressed or not for some reason I think there's an issue here in this knob thinking it's off and on so what happens is I can hear the little flap in my system for the outside air verse recirculated air opening and closing and all sometimes get you know outside air blowing in on my feet from underneath and also I can hear the air conditioning compressor kicking on and then kicking back off like quickly multiple times as I Drive down
