Shankmonkey Posted June 17, 2020 Report Share Posted June 17, 2020 I've had my 2010 Journey 2.4L for 4 years now and the A/C worked when I got it. This summer I turned it on but there was no cold air. I checked the fuses and they were all good. Then I checked to make sure the clutch was engaging with the compressor. It was on engaged and so I turned the A/C off and it was still engaged. I unplugged the wiring harness going into the A/C and turned the car on and the clutch was still engaged. So I'm thinking the clutch is seized. I pressed the valve on the high-pressure side and I couldn't hear or see anything come out so I'm thinking I have a leak now too. My biggest concern is driving with the compressor always turning, I don't want it to seize and my belt to burn off. I'm wondering if it's as simple as replace the compressor, and take it to a shop to be refilled? Pepboys has a free leak test they offer but I'm a little skeptical about taking it there to see if they can find a leak. I'm open to any and all ideas on what to do next.

Shankmonkey Posted June 17, 2020 Author Report Share Posted June 17, 2020 Unfortunately I’ve heard a few stories like that, I’ll check out an ac shop and see what they say. Quote Link to comment Share on other sites More sharing options...
OhareFred Posted June 18, 2020 Report Share Posted June 18, 2020 Are you positive the clutch is engaged? It might look like it is because the pulley always spins. If you look at the front of the compressor and it’s not turning the clutch is not engaged. Please don’t be offended, not sure how familiar you are with the ac system is all.....?

Shankmonkey Posted June 18, 2020 Author Report Share Posted June 18, 2020 No offense taken at all haha, I can't count how many times I've started to work on a problem to later realize it was something simple I had overlooked or should have looked at in the first place. I looked at the pulley and it was spinning, and the hub was also spinning. I watched it and never saw it disengage, and even reached down and felt the inside lightly with my hand to feel the hub moving too. I checked it again with the A/C compressor unplugged and with the A/C off and had the same results. I'm also not super familiar with A/C systems in general, but from what I read, it seems like if my compressor clutch was truly seized, then my compressor would have likely burnt up by now as I've done some 7-8 hour drives in the past few months for work. I suspect it might be a Clutchless system with a Variable Displacement Compressor. This would make sense as in this type of system the pulley-wheel always spins, even when the A/C is off. I know I have low/no pressure in the system and the A/C slowly got worse over 2 summers so I have a leak somewhere and will probably just get the system evacuated and filled with some dye and then find the leak at the end of summer and fix the leak and go from there.

John/Horace Posted June 18, 2020 Report Share Posted June 18, 2020 (edited) But clutchless is newer tec and the Journey hasn’t been updated at all in years. Still a 4 -6 speed tranny and hydraulic steering. Here is a photo of your compressor with a big clutch driven pulley from RoackA. And clutch pic.

Shankmonkey Posted June 18, 2020 Author Report Share Posted June 18, 2020 Well now I'm good and confused. I looked up the AC compressor model online and it said it was clutchless, and I can't imagine it running the entire time for the two 8-hour drives I took without seizing. But that is an electromagnet clutch there like I thought. So I'm at a loss now. Quote Link to comment Share on other sites More sharing options...
Shankmonkey Posted June 22, 2020 Author Report Share Posted June 22, 2020 In case anyone else was wondering, I contacted DENSO and gave them the part number and they responded today with: Quote Link to comment Share on other sites More sharing options...
John/Horace Posted June 22, 2020 Report Share Posted June 22, 2020 Interesting. There is even a Mopar clutch coil listed for our Journey compressor.

Shankmonkey Posted June 23, 2020 Author Report Share Posted June 23, 2020 Yeah it’s pretty weird, I’m not sure what to believe at this point. Quote Link to comment Share on other sites More sharing options...
