Hey guys. I've got a 2000 F-150 Lariat SCrew with 241,xxx miles. The other day, I went to turn on my A/C and there was nothing there. Blower works fine everywhere else, just not getting the chilled air that I'm expecting. I purchased a couple cans of r134 to put in, but when I hooked the hose up to the low side, the pressure read over 80psi with the a/c off. When I kicked the a/c on, the pressure didn't change.

I'm assuming that the freon is good and doesn't need a recharge because of the pressure and it not moving. Any ideas on what I should check, or how? Yes I'm a novice, and just want to attempt to figure out what I'm looking at. Don't want to drop $1000+ on this repair at a shop, as I don't think it's worth it. More, I want to narrow down what could be the problem to determine if I want to take it in or not. Thanks for any help on this. I did do a search, but couldn't find anything to help.

 

When you turn the ac on does the comprossor clutch turn on and spin with the belt? Do you have power and the clutch? Fuses good? Switch good?

 

I don't hear the clutch kick on, but I did see the compressor's wheel spin with the belt this morning. I check the fuse under the hood and it was good. Swapped the relay with another, and there was no change.

 

Something tells me I'm in worse shape than I thought. Here are a couple pics of the face of my compressor. Why do I have a feeling that I lost an important part off the face and I'll need a new compressor?

 

You are missing the clutch. That sucks. You might be able to get just the clutch and pulley. But my guess you will be end up putting the comprossor on that comes with the clutch.

 

You're looking at about $300 in parts-tools and 3-4 hours of labor. Likely the compressor is seized and the clutch got launched. New compressor, orifice tube, and accumulator-drier $200 from Amazon (for example), plus $40 vacuum pump , $5 oil, $25 gauges, and $20 R134a. YouTube video to show you how to replace, evacuate, recharge.

I'd take it to a pro for the re charge. It needs vacuumed down and filled with the good stuff. ( not the stuff you buy at Walmart for $8 a can.. )

 

Just curious. After some research, am I missing the whole clutch, or am I only missing the hub? Looking at autozone for the parts, it looks like the clutch has the pulley still there as well as the bearing. It looks like I might have lost the spacers/shims and the hub. Or am I not looking at that right? I could very well be wrong. Thanks for the help so far everyone!

 

This is the first time I have ever read there could be different qualities of r134. Has anyone else ever heard of this?

 

there's a difference when it's done right and done with a can. It's the same if you vacuum it down and everything then use the can.
