[QUOTE="MTF, post: 900273, member: 499"] Alright I got a 8.2K which read 8.049 on his Ohm tester that the crane tech had. He tested a bunch of resistors with his Ohm meter because he has about a 200 of them just thrown in a bag. I just threw it in this afternoon and while the compressor does not cycle any more. The big line out in the engine bay is really cold and sweating all the way to the compressor and I do feel a difference with the air coming out of the vents. Is it as cold as my old 1997 2dr. Chevy Tahoe was, [B]NOPE!!![/B] Hell I used to see vapors coming out of the vents in my Tahoe. LOL So I called the crane tech and told him I gave him the wrong numbers. After rereading Z7What's post. I told him I needed a 8200. I know I screwed up. LOL He said he'll have 1.2k that's about the same as a 820k for me next time I see him. What do you guys think, can I leave the high 8.2K resistor in without burning anything up? I understand that I may freeze the evaporator up, but I doubt it if the fan is on high. I have almost read all the threads on F150 forum, I see the guys are using 670K to 1.2K with adding an extra 12 oz. of Freon. I never checked AC in five years and I have all the professional tools. I even have all the professional adaptors for R12 and 134a, import and domestic. Can someone please tell me what the high and low pressures should read. And I do understand that it's all about oz. and not so much pressures. I just can't find what the specs are for our Raptors. I found out that the PCM monitors the high and low sides and will shut the clutch down if either are to high. [/QUOTE]
