Hello,
for the life of me I cannot figure this out. Acquired a new truck, ac blows hot. Manifold gauges I rented at parts store show low and high side are both at zero psi. I ran a vacuum pump for about a half hour or so, then went to add r134a. The truck wont accept the charge. The point of this was to add a charge with some dye, maybe enjoy ac for a little while before it all leaked out, find the leak and fix it. However The Freon makes it into the gauge but sits there. I noticed the compressor isn't spinning, which I assume is from lack of refrigerant. Okay, cool I'll just jump the low pressure switch. So the compressor is now spinning, but Freon will not make its way into the system. low side reads 90psi when I release the valve for the can. Low side is open at the gauge. I dispel air at the gauge and it falls back to zero, and then that's it. High side is closed at the gauge. Car is running with AC on. Any ideas are much appreciated. I would also add that this truck previously had ac and was working.
Respectfully, please fight the urge to tell me I'm in over my head and to take it to a professional. I'm using this as a learning experience, thank you.
