i have a 2004 6.0 powerstroke bulletproofed, CAI, rudy’s y pipe, straight pipe exhaust. i had the ac compressor go out on my truck, so i waited about a week or so to change that so the part could come in the mail. during that week my ac just completely stopped blowing the flaps still move in the ac but it doesn’t blow. a week goes by i finish another cummins project, jump on my truck and put a ac compressor in and a new blower motor. none of the fuses are blown!!!! so i turn the key still no ac out of the vents doesn’t blow at all. the light in the switch comes on but doesn’t blow, checked all my connections and they are all good. i went to youtube and some guy said if it’s the resistor it will only work on high with the heat on so i try it and still don’t get the ac to blow. it’s a 2wd extra cab XLT. i need help asap i live in arizona so it’s hot here please help!!!!!!
