An AC accumulator and an AC drier serve different functions in an automotive air conditioning system. The accumulator is designed to store excess refrigerant and prevent liquid from entering the compressor, while also collecting moisture and contaminants. In contrast, the drier primarily removes moisture from the refrigerant and filters out impurities, ensuring the system operates efficiently. Essentially, the accumulator is more about managing refrigerant flow, while the drier focuses on maintaining the quality of the refrigerant.
You can refill the AC 2001 Lincoln navigator is located on the accumulator or receiver-drier.
Usually at the top of the accumulator/drier at the passenger side firewall
because its colder than the external temperatue there fore it condensates
lOOK NEAR THE PASSENGER SIDE FIREWALL PERHAPS NEAR DRIER/ACCUMULATOR
On all GM products it is almost always on the accumulator / receiver drier.
Probably on top of the drier accumulator at the passesnger rear firewall
Fully charged? Bad pressure switch on accumulator/drier? Blow fuse?
Its on the Receiver Drier/Accumulator. I found a drawing of it on the site listed below.
It comes off the accumulator/drier and looks like a air pressure valve only about 2 times bigger.
Look for pressure switch on top of accumulator/drier normally at the passenger side firewall - jump this switch with paper clip or ? That should pull clutch in
Check fuses May need a refrigerant charge Jump ressure switch at the top of the accumulator/drier to see if compressor starts
Next to AC accumulator/drier, which is in the engine bay in front of the firewall. When looking from the front, it is on the left side of the car, an aluminum cylinder approx. 4 inches in diameter.
