Caravan/Voyager :: Hissing Sound After Turning On Rear AC
Jun 20, 2014
I've got some trouble with my 2010 T&C Touring and the A/C system. I believe it is specific to the rear, but not 100% sure yet.
Here's the symptom, while driving home a few nights ago, I noticed a hissing sound from somewhere under the dash. Research led me to believe that the r-134a was low, so I bought a few cans and charged it up. I drove around yesterday with the fresh refill, and all was well. This morning, I noticed that I hadn't been running the rear A/C, and thus, not doing a full test.
So, I turned on the rear A/C and within just a few minutes, started hearing the hissing sound again. Flash back to a couple of weekends, I replaced brakes/rotors and while inspecting after taking a test drive noticed some water pooling up under the rear passenger side tire. I checked it out, but at the time, it didn't seem significant until today when I started to put this all together.
SO, my question is, what would be leaking right above the tire? Is this something that is super common and I could somehow convince my local dealer to repair out of "good will" like was happening with the '06 model year with a similar issue? I've had to do brakes, rotors and as a result of not knowing that Chrysler calipers can't be pressed in, but instead must be wound in, replaced calipers, and also an EGR valve all at the same time. So, needless to say, I'm not excited about doing further repair.

When we turn the wheel of the van sharply in either direction, it produces a distinct clunk from the rear. This isn't the AWD engagement symptom I've read about - it seems to be strictly connected to a sudden change of direction, and the noise is definitely coming from the rear. I can also get the noise to happen when going over a large bump, such as a speed bump, but a moderately sharp (so nothing you wouldn't do in normal driving) flick of the wheel produces the noise very easily and consistently.
I doubt it's the axles, because the way we drive this van, the AWD is actually seldom engaged, so the axles have seen very little wear. Could it be the rubber bushings that support the leaf springs? It's such a simple rear suspension design that there isn't a whole lot to go wrong/replace, but I don't want to start throwing parts at it without at least a stab at a diagnosis.
The van has 123,000 miles, and has been doing this for a long time, and it doesn't seem to be getting any worse, but I'd like to get to the bottom of it. Otherwise, the van has been amazingly trouble-free.

It is as an electronic whistle/humming. The sound is coming from the rear of the van, and no, not when it's moving, even though it still does it when moving. The only thing I can think of would be the fuel pump. Because It's loudest just before the rear tires, not after them. My fiancee has heard it twice now, when she first heard it, I didn't, but this last time when I heard it, I also noticed that the gas gauge was reading just below 1/8 of a tank.
Would like to know if it's the fuel pump or something else I'm no thinking of. And if it means I have to replace the pump.

I'm wondering if there is a 100% way to check and see if my climate control module is bad. No lights work on it, it doesn't turn on the ac or the blower. I took it off it all seems to be decent from what I can tell. But its just not working.

I'm having electrical issues in my 2006 Dodge Caravan. It started with the radio not working (even though the lights around the nobs and buttons light up) and the lock button doesn't work until the van is started. Now, the windshield wiper won't turn off, even after the van has been turned off.

Bought this cheap 93 grand caravan 3.3 with about 350,000km about 750km ago and it had a bit of a whining sound from the start, thought it was normal for it's life. Last night I was taking my daughter and infant grand-daughter home when there was a terrible clunking, grinding and rattling sound coming from the engine. It was about -20 outside so I decided to just limp it home, but when I got a block from my daughters house I lost power steering. I checked under the hood an saw the belt on the left side with all the pulleys had come off and only one pulley near the bottom was spinning. after trying to spin the other pulleys i noticed one wouldn't spin ether way,and was really hot. thought it might have seized up and threw the belt. Is there a pulley in there that's not supposed to move freely, and if not what should I do now?

I have a 99 voyager that has started making a whirring sound this last week. The water pump, serpentine belt, tensioner have all been replace several months ago. The battery light came on for about a minute and then went off the last night. I checked the voltage with the engine running and it measured 12.5, the same as when it is off. When I revved it up the voltage went up to 14.4 volts. Is this normal? What could be making the whirring sound?

I have a 2008 Dodge Grand Caravan SXT with 58000 miles. The rear blower won't run with either the front controls or rear controls. I have checked the fuses and they looked ok.

I just bought a 99 f150. Its in great shape only 65000 on it but there is a hissing swooshing sound when turning the wheel... not really any brake sounds. The truck has been maintained and I dont see any leeks in the ps system hoses. I didn't know anything about the atf fluid in the truck... and I haven't added either ps or atf fluid to it. I'm wondering if that is maybe something the dealer i bought it from did. or maybe one of the shops the previous owner did. Would ps fluid cause these kinds of sounds? Do I need a flush of the system.. How to do that.

My car has been making a hissing sound when I turn it off for the past few weeks, I checked the hoses around the intake manifold and they all look to be attached fine.
I took a video and discovered a flex in the rear of my manifold..is this normal? What would be the common issue?
Look at the rear of the barcode label

Noticed hissing sound coming from the rear windows when the AC is on... It's very annoying so I always crank up the volume of the music. Funny thing is when you open one of the rear windows slightly and the sound is gone. I thought it was from the roof rack but it's not.......coz the sound is there when the car isn't moving too.....as long as the AC is on.....and the rear windows are closed tight.....

So I ended up removing my rear seats of my 2010 hatchback gs, but there is now a hissing sound coming from the rear where the seats were. The sound starts as soon as I start the car up until I shut the car off. I'm assuming that this noise has always been there just noticeable because of the seat removal. Is this just the fuel pump?

I have the '03 Lincoln Aviator 4.6 DOHC. It has a noticeable knock/ping/chatter and somewhat sluggish acceleration. I notice the PCV hose was collapsed and shredded. I replaced the hose and valve, didn't change idle or acceleration and I still hear the hissing noise in the same region. I unplugged the EGR valve and started the truck, the idle was the same as before I unplugged the valve. could a bad EGR valve give a vacuum leak that is hard to detect? I tried testing for leaks by squirting starter fluid near the suspect areas, and I couldn't detect anything.
could a bad PCV valve be caused by a bad EGR valve and/or vise versa?

Well I've just noticed something quite annoying today... a very slight hissing sound coming from under the rear end of the car. A friend I drove to work this morning even said "what's that noise?".... It reminds me of the sound you'll hear when there is a pinhole in a joint weld, or a clamp is loose? My car only has 2800km on it!

We just purchased a 2012 Grand Caravan and was wondering where to get a key and program it. I know the key will be an arm and a leg if i get it from the dealer. Is there a tutorial that tells how to program it as well?

2006 Caravan. Heat comes and goes every minute or so. Also noticed the temp gauge goes from normal operating range to cold and back again frequently. Hasn't overheated. Does that sound like a thermostat problem?

On my 2005 3.3L Grand Caravan the ABS light keeping coming on. I inspected the sensors for the front and used my compressor to give them a quick puff of air to get rid of dust. The light went off for about 5 days. Now it is back on.
How does one read ABS codes? If I knew for sure that the problem is a speed sensor and which one I could clean or replace the faulty sensor.
If I clean to sensor are there any special precautions I need to take? As far as I could see they didn't look very dirty.
