Review on 🧹 High-Performance Electric Vacuum Pump for Ford E-350 E-450 Excursion F-250 F-350 F-450 F-550 F650 F750 Dodge Ram 2500 3500 - Replaces OEM Part Numbers: 904-214, 53032373AA, 4C3Z 2A451 BA, 53032373AB by Richard Dean

I installed this on my 6.0 F-350. This fixed my AC stalling and 4x4 issues. However, it is VERY LOUD. I had to give it one star less for "Transparency" and an overall 4/5 for noise. At least I know it works I think. My air conditioner stopped working on day 117 in California. At first I thought it was a resistor, I replaced it, it still doesn't work. Replaced the fan motor, I have fan speed control and good air but only defrosting. It was found that the vacuum pump opens the blend doors and was defective. Replaced it with this part and everything works fine. Later I will check if it still works or not. So far, so good.
