The H-block on the firewall gets retarded and sometimes doesn't allow the freon to go through.The best way to check and see if this is what is going on is to take a screwdriver and use the handle of the screwdriver and hit the H-block a couple of times while the A/C is running. If this is the problem, it will start cooling in the front. If this clears it, you might want to check with an air conditioner shop and see if they are able to filter the system out since putting a new H-block on won't solve it if the system has dirt in it. Good luck!

2010 dodge caravan ac gets cold then hot

2 things come to mind the first is are you stepping on the gas to accelerate when it happens this will be caused by a vacuum leak somewhere in the emissions or under the dash/ second are you standing still and you feel the air get hot if this is the case your cooling system is running hot and the heat is transferring to your a/c condenser and making it hot reducing the cooling effect of the Freon because it is getting hot itself

Air Conditioning question

Let's do the overheat first.
Your van should have 2 electric fans or maybe 3, under the hood and directly mounted to the radiator.
There are usually two behind the radiator, and one in front, or visa-versa.
One of these fans is supposed to kick on immediately when you start your AC. It is probably not doing so.
The 2 things that usually cause it to fail are a bad relay or a bad fan motor.
While you are checking all this, be sure to check the other fan and fan switch (screwed in to the bock) and make sure it is working right.
The second part is much harder.
Here in Florida, where it is nearly always AC weather, I've noticed that when the van gets hot, it can take 1/2 hour to cool it. ( 100 degrees).
I have found some cars just never really cool down, so I make a real effort to always park in a shady spot and/or under a tree, and that makes a big difference in the passenger comfort.
Some car pats stores sell a dash-mounted electric fan, the kind people used 70 years ago.
Be blessed.

1999 DODGE CARAVAN directionals hazzards and ac/heater fan are all inop at the same time?? winshields wipers work..horn works..and the ac appears to work but unable to push out any cold air..

The first thing to check would be the fuses, this problem may be related or maybe not, so check fuses, make sure to test fuses under the hood in the engine compartment.

Compressor on 96 dodge caravan will not start even after charging system with freon. does computer have to be reset

check for bad fuse under hood. also check for ac relay issue. also under hood . you will find a power dis. center under the hood. (just like a fuse panel)the system does use pressure switches, but check the fuse and relay first. if you have power and ground at the compressor and it does not engage, then the ac clutch is bad. you can check that at the two wires at ac compressor w/ a test light.

Where is the heat/ac relay located on a 1997 Dodge Grand Caravan?

1997 Dodge Caravan puts out warm air

Your car uses R-134A, readily available at most auto parts stores. Best bet is to get a refill kit that includes the refill hose (get one with a pressure gauge attached if possible to ensure you don't overfill the system). Recharging is pretty straight forward. Turn the car on with the AC on HIGH, locate the low side AC line (will have a screw on cap). Attach the refrigerant to the hose but don't puncture the can until the other end of the hose is attached to the low side valve. Once both ends are attached, turn the screw on the hose to puncture the can of refrigerant; the car should suction the refrigerant out of the can. Disconnect the hose when the can's empty and check the vents on the AC. If its cold and frost develops on the AC lines under the hood, you're good to go. Best of luck and post back with any questions.

See if it runs when you turn the a/c on. If not Check the coolant level when cold. Check the fuses under the hood. Check for power at the fan when hot or with the a/c on,should have power. If power,then replace the fan motor. If not it get's deeper.

The van suddenly stop

Sounds like you are having a fuel pump problem. I'm dealing with the same thing right now. There is a Dodge Grand Caravan recall for the fuel rails. I would check into that. I would also check your relay for the fuel pump (in the fuse box under the hood). The recall could cause air to be sucked into the fuel filter so that could be a problem also. I hope that this helps!
