Why won't the air conditioner clutch will not engage to start the air conditioner


If the clutch cycles on for a moment, then stops, and repeats, it's low on Freon. If it never even tries to spin the fuse my be blown.

How much freon does a 2002 dodge intrepid hold


It does not use Freon it uses 134a and it depends on condition of compressor and how much is in it. I would go to Auto parts store and buy 2 cans of 134a with the gauges on them if you read the can or the gauge it shows you when it is full. Make sure you connect to the Low side of connection.

Locating the High side and Low side AC gas ports


Easy. find the compressor. The larger hose attaching to the compressor is the "suction" side. This is where you install the refrigerant.

The smaller hose, whether rubber or metal as it travels to the passenger compartment, is the high pressure side.

After installing refrigerant and as the compressor is running, the larger hose will feel cool and the pressure side will feel hot.

I need to retrofit and recharge my 1988 Dodge Ram Ac.


First, the old R-12 must be completely evacuated fromt the system. R-12 and R-134A do not mix and won't function together. Once you are sure there's no R-12 left in the system, you need to install an R-134A fill valve on the low side AC line. This is where your refill hose will connect to add R-134A. Once the valve is in place you're ready to fill the system. The compressor requires a minimum of 20psi to engage and should not be filled to more than 45psi.

RECHARGING AC SYSTEM

1.Turn the truck on and turn AC on HIGH
2.Locate the low side AC line (will have a valve and cap similar to the cap on a tire)
3.Insert the oil or R-134A can to the hose (Do not turn the screw to puncture the can yet)
4.Insert the other end of the refill hose to the low side valve
5.Puncture the R-134A can with the screw on the refill hose
6.You should feel the system suction the refrigerant out of the can
7.Check for frost on the AC lines and the air blowing inside the truck
8.If frost develops and the air is cold, you've successfully recharged the system and disconnect the refill hose. DO NOT ADD MORE REFRIGERANT...overcharging the system will damage your compressor and will be less effective
Hopefully this answers your question and you're able to get your AC working again. Best of luck.

On my 1995 Dodge Ram When I turn the A/C On it dosent seem to kick in and get cold just warm air?


In most cases, the problem is the system is low on refrigerant. The AC compressor requires a minimum of 20psi of refrigerant to turn on. There are refill kits available at the auto parts stores. If doing this yourself, select a kit that includes compressor oil, and a refill hose.

RECHARGING AC SYSTEM

  1. Turn the truck on and turn AC on HIGH
  2. Locate the low side AC line (will have a valve and cap similar to the cap on a tire)
  3. Insert the oil or R-134A can to the hose (Do not turn the screw to puncture the can yet)
  4. Insert the other end of the refill hose to the low side valve
  5. Puncture the R-134A can with the screw on the refill hose
  6. You should feel the system suction the refrigerant out of the can
  7. Check for frost on the AC lines and the air blowing inside the truck
  8. If frost develops and the air is cold, you've successfully recharged the system and disconnect the refill hose. DO NOT ADD MORE REFRIGERANT...overcharging the system will damage your compressor and will be less effective

COOLANT CHARGING


things you need(to do it properly) vacuum pump,r134a gauges and leak detection of some sort first locate lowside port connect blue connector from gauge to it (lowside is the skinny hose)connect vacuum pump to yellow line open valve on blue guage manifold.
pull a vacuum to less than 30" hg for thirty minutes.close bluevalve on manifold watch needle make sure pressure doen't rise if no change in pressure after 15 minutes no leak.if pressure does rise then you have a leak and need to find it.(cheap/messy way use get a can of 134 with dye in it fill system and let it run look for dye on system usually on pump around back of clutch,unless you replaced a compnent recently then check all fittings and seals.)
you will add r134a through the yellow hose.
