Question about Heating & Cooling

1 Answer

I have a 2002 Ford Expedition 4.6L. I am attempting to add fren 134 to my system. I have a recovery unit and prfessional guages. I simply am not able to find the low side charging port on this vehicle. I have looked high and low. No low side port visible. Does any one have a handle on what the answer might be? Thanks a bunch for helping out.

It should be on the accumalator or on the compressor hose they have them in different places and in three different places, look for the low side switch and you could vav it down there and charge itthere if you use a paper clip to keep the compressor going.

Where is the fuse for the air conditioner on a 2002 ford explorer?

If compressor not engaging, could be low on R-134 from a leak in the system. There is a low pressure switch in the system that prevents it from coming on if it's low on R-134.

Where to self charge a/c unit?


Before attempting this make SURE your vehicle is running R-134 coolant. If it is running R-12, you will have to have this done by a professional. DO NOT attempt to mix R-12 and R-134 coolants, as this mix will become volatile and could possibly explode and cause massive system damage. You can find out what type you are running by looking for a ( usually yellow) decal on top of the A/C compressor or on top of the air accumulator ( the silver soda can looking thing.) Once you confirm you are running R-134, trace your A/C lines back from the compressor until you find two nipples, one large and one small. The large one is your "low side." This is where you will attach the recharge kit to service your system. The recharge kits are designed to only fit on the low side, so you won't have to worry much about confusing the two. Hope this helps you out. Have a good day!

Reseting the keyless entry on a 2000 ford expedition


unfortunately, ford does not allow this. Instead the system can only be programmed to add up to 8 different codes. The only alternative is to replace the security control unit.

2002 ford expedition air conditioner needs R 134 refrigerant. I cant seem to locate the service port.


The low pressure valve on the 02 expedition is located on the accumulator on the passenger side fire wall. The accumulator is underneath the battery relay and a grouping of wires. Had to squeeze hand underneath a heater2_bing.gif hose and an a/c line to remove cap and hook up hose. Nothing has to be removed to locate the valve just a little touchy feely. Valve faces a 45 forward toward the engine.
