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.

Replacing a/c compressor or cluth on 96 dodge caaravan 3.8


IF the clutch is not engaging it may be due to the Freon being low. There is a low limit switch on the AC system. You can verify that by checking the pressure, or using a meter to check the clutch.

99 Dodge Grande Caravan the A/C blows hot air and a hissing sound under dash


Well the hissing sound could be a vac leak or the freon flowing thru the system.
Someone needs to check the freon charge in the system with a gauge and the electrical circuit to the compressor clutch.

HI there #1 before you put freon in did use a vacuum pump and pull too the right vacuum
specification if not you have air in the system.
#2 if you put 4 cans of freon you over charged the system must vehicles a/c systems use 1lp 5oz
you must remove freon first and use vacuum pump and put system in vacuum for abut 1hour
too mack shore system is air and muster free.
ones that is don you can charge system be careful not too over charge OK

How do you connect a/c charger to make your central air cooler


The 1998 Dodge Caravan ac should be charged at the low pressure service port. This port is located on the suction line near the compressor. The suction line can be identified by it's size, it being the larger of the two line connected to the compressor. You must purchase a recharge kit at your local part store, which should include charging hose with pressure gauge and a can of R134a freon. Gloves and eye protection should be worn during servicing.(freon can freeze your eyes and cause frost bite to your hands). Connect freon to charging hose, connect charging hose to low pressure service port, open valves and start engine, turn on ac. If compressor won't start it may be required to disconnect the low pressure switch and jump out the connector.

Ac not blowing cold


Check for a loss of freon, if it is low, check for leaks. If the system is not pressureized (ie: low on freon) the computer will not let the compressor or cooling fan activate. If it is not low on pressure, then systematically check each part of the system for operation.

A couple of ways to find out what, exactly, is wrong. One start your van and look under the hood. If you turn you A/C both pullies on your Compressor should be turning. If they are your second option lies in the systems charge. If you locate the aluminum lines for your A/C system you can unscrew the cap and push the valve down (Very gently) with a screwdriver or even a nail. If nothing comes out you need to buy R-134 Freon and charge your system. Hope this helps.

Air Conditioniong not working


U may be low in Freon gas.
When Freon is low there's low pressure switch that will prevent A/C compressor clutch from engaging to protect it from failure.
So, first check Freon pressure & any leaks form lines & hoses fittings.
Even if the fan is working, that doesn’t indicate proper compressor OP'S.
Look at the compressor front side you'll see the clutch stationary while the AFT pulley moving.

Then put air-condition compressor switch to ON (Engage),
You should see the clutch engage & start rotate,
If NOT, this is very clear indication u r low in Freon.
