There's a guy on eBay that sells new a/c units for close to half what the dealer charges. I forget the username, but if you do a search for dodge a/c it should come up.

As for replacing the a/c pump, it's not too bad. The first thing you'll need to do is remove the serpentine belt and then SLOWLY loosen the bolt on top of the pump that connects the a/c lines. The reason i say slowly is that the refridgerant and oil will leak out and you don't want the oil spraying all over everything.

Once the refridgerant is gone finish removing the bolt, but be careful not to lose the two washers. Remove the triangular plate on top of the a/c pump as well as the two front bolts (on top). Disconnect the two electrical connections and the pump will come right out.

Installation is the reverse, but be sure to take your Dak to have the system evacuated & recharged.

Nope, don't do it. Venting is a $10,000 fine if you get caught plus it's just not good for the environment. Not a tree-hugging enviro-nazi, just try not to intentionally do things like that.

To change to clutch assy. you only need to unbolt the compressor and prop it up. It's a little difficult this way but you save the cost of recovery/evacuuation/recharge. Go to this page for instructions:

http://www.sanden.com/support/servicemanual/english/clutch.htm

Problem now for you is the special tools. If you know someone that does this work or owns a shop, you maybe can borrow the tools. If not, it is more cost effective to pay someone to do it.

How do you know you clutch is the problem? If you have a multimeter disconnect the connector and measure the resistance between the two terminals (this is the one with the blk/blk and wht wires). Lemme know what this value is.

I took the truck to Autologic, which is a pretty reputable place here in town. They spent a good 45 min. trying to figure out what the problem was and eventually figured out it was the clutch...i honestly dont know much about the ac units themselves, im more of an engine/stereo person...what kind of tools would i need? the autologic place said it would probably be $300-350 to replace the clutch, with labor and all...is that good? thanks.

OUCH!! Bad thing is they know they've got you. I'd call a couple of other shops, tell them exactly what you want done and see if they'll give you a ballpark figure.

With labor rates going thru the roof these days that may be not too far off. I hate seeing people get raped by shops! But,by the time you buy the parts, the special spanner and puller, refrigerant and pay someone to recover and then evacuuate it might cost about the same. Like I said, call around.

I believe my AC clutch has gone bad as well and was hoping someone could follow up on this thread for me.

AC clutch never engages.

I hooked a pressure gauge up to the low side port and it has 25PSI, which is at the low end of the "Safe" zone on my guage.

I can turn the compressor over by hand easily, it is not frozen up.

I disconnected the connector coming from the AC clutch to the wiring harness and probed it with a multimeter. There is infinite resistance when I probe the harness side of the connector, as I assume it should be. One lead ground, the other lead a signal wire (pos). I also used a test light to confirm the ground is good.

When I probe the AC clutch side of the connector, I get NO resistance, showing the two connector leads are shorted together somewhere. I assume this means I have a bad AC clutch?? Makes sense to me too since I keep blowing fuses (AC clutch fuse in the fuse block under hood).

Can someone please confirm that this is an indicator of a bad AC clutch? Also, what pressure should I charge my system to? The POS Haynes manual says nothing about the AC system, only "This manual does not cover the AC for legal and health hazard reasons." Well, taking the Dak to a shop and bending over is a bigger hazard to me, so I'm doing this myself.

I'm going to try doing it without disconnecting the compressor so I don't vent and have to recharge. I found a clutch @ NAPA for $92.

Disconnect the plus wire from AC cluch > Start engine with AC turned on ( This is only so if cluch is working you can conferm the AC is working ) >> run a wire from plus on battery and touch it to the plus on AC cluch > If it ingages your promlem is somewhere else > If it don't you know you need a cluch >> Hate guessing games lol

If it is showing 0 ohms, then yes it is shorted. The test OB described will tell for sure. If it engages your system is very low on refrigerant-hence the 25 PSI reading you got. you really can't charge an automotive system just by pressure, leave it to a pro.

If it is the cluth, why not pick up a clutch and compressor from a salvage yard and not mess with just trying to replace the cluth? I got mine for $65. New compressor w/cluth was $350/450 depending one remanufacturered vs new. It's not as fun as fixing the cluth, but will get your cold A/C sooner rather than later. I'm almost always about some convenience.

AC Clutch
IP: Logged

Message:
2 years ago. I replaced the A/C clutch on My 98 Dakota. I knew the clutch was bad because it would engage for a few minutes then crap out. Next, I energized the clutch directly and same thing - It would engage, then disengage.
From what I understand, that happens only when the coil around the clutch is bad or the clutch disk has excessive wear on it. When changing the clutch, I only neaded a simple puller and a snap ring plier. It took about an hour and it worked great. You can purchase the clutch from a dealer in NJ for about $150.00 http://www.chryslerpartsdirect.com/
They have a GREAT website and the prices are pretty good.

how hard was it to replace the clutch, did you have to mess with recharging the compressor or anything like that or was it a simple removal of the compress or and clutch install and install or what???

according to what i've read in a FSM. you can remove the clutch w/o de-pressurizing the system. because i am going to have to remove my a/c clutch to change the dam coil. it shorted on me and now i need to change it.

it's not a factory Sanden comp either. a body shop had to replace my original comp in Dec. 05. i just found out from them that they bought the comp for my truck from O'reilly's. it worked as well as the Sanden just didn't last as long.

I have a 2000 dakota, 4.7, I believe my ac clutch making a grinding sound. This sound comes and goes, weather the ac is on or off. My question is...Is this sound common when the ac clutch is going bad? ( When I first heard this sound I thought my water pump was going out)Any thoughts?

I have the same truck, 2000 w/4.7. Yes, it will
start off as a grinding sound,usually when the a/c
is not engaged.

In my case the bearing on the clutch failed, not the
compressor bearing. When the a/c or defrost was on
it was whisper quiet, as soon as the clutch opened,
it growled. I ended up with a new compressor,
cheaper and with a warranty.
