    I have the 7.3 fan clutch conversion and its working well, but it's hot here. I mean 105 to 115 and the clutch seems to be my A/Cs cryptonite. I have a completely brand new ford oem A/C system that has been charged twice as when at a light or if standing still the A/C gets warm while moving its...

    Howdy...I am replacing my AC condenser in my 2018 F250 6.7 Super Duty. Because it's still relatively new I can't find any helpful videos for the removal/replacement. I am no expert (though I not a complete idiot either) and have a buddy coming to help who knows what he's doing. I was able to...

    I'm trying to diagnose a problem that I had last weekend. While driving up to see a friend and Show Low Arizona I had switched the AC to defrost to see if it would cool the truck down a little better due to the heat on the windshield. After I noticed it wasn't helping I switched it back to dash...

    So i bought a 2008 ford f350 6.4 and the a/c did not work. I took it to get it charged and they said it would not take a charge that there was something wrong with the system. I took it to ford and they said that the condensor was leaking and they wanted about 900 to put a new one in. I took it...

    Can someone please draw me a map to the low pressure switch location? I can't figure out where the heck it is. Also, how do I jump the compressor after deep vacuum? I had the A/C evac'd today and put a new orifice tube in. I guess I thought it out until about now. I was following the...

    I moved to Chicago last year from Arizona, from super hot summers to really cold winters. Last year I added the Max AC Assist from Diesel Site. It worked great, and the cab was very cold. Now that I've been through a cold winter, the weather is warming up, and I went to start using the AC...
  13. 6.0 Motor problems
    So after enjoying nearly a year of issue-free 6.0 driving as it should be, this afternoon the gremlins have returned. My ABS light came on after feeling a slight pulsation in the brake pedal as I was turning left, slowly in the parking lot. My initial thought was bad speed sensor, but I JUST...

    We had a couple of warmer days and I noticed my A/C was working intermittently. It works at idle, but any rpm up to 2K and it will start cycling on and off every 5-7sec. At 2k it will stay running longer up to 2 min before it cycles as long as the fan is on high and the A/C is set to max. I...

    Drive to work and the AC works great. Drive to lunch and no AC at all - just blowing warm air. Strangely, the air coming out isn't humid. This is my first diesel and I've only had it four months so please dumb it down for me. As far as I can tell, the fan doesn't kick on at all. At any...

    Did the 1995 F350 XLT come with a cabin filter? My truck doesn't blow much air through the vents.
