Question about 2000 Lincoln Navigator

1 Answer

Rear air conditioner pump

The rear pump for the air conditioning in my 2004 Navigator is making thumping noises (not able to turn over?), and thus there is no air coming out of the rear vents. Please advise if this problem can be solved by purchasing parts or do I need to take the vehicle to the dealership?

My husband needs to know if there is a fuse that could fail and make the rear air conditioner blow hot air.

no....This is the rear A/C & heater actuator blend door malf/broken. This is very common on expeditions and I encountered the same issue in my 2006 expy. This door switches from hot to cold vents, once stuck only hot air will blow. Also, is there any thumping or tapping noises from the right rear panel (this is where the rear a/c unit is)???

How can i check if the air compresor is working on my 2004 navigator air suspension system

When you first turn it on in the morning the compressor should come on to level the vehicle. They are usually mounted under the hood or somewhere in the rear of the vehicle and will make a slight buzzing noise when you get close to it.. You will know its working when the vehicle stays level and has a somewhat cushioned ride (the air struts have air in them)

2003 Navigtor rear AC tnhuping noise ..could be a fan belt?

It sounds like your blower motor wheel is off, or broken. You will need a new wheel at minimum, probably should do motor at the same time since you are already there.

Rear air conditioner pump

there is no separate pump for the rear a/c. front & rear operate from the same a/c compressor in the engine cmpartment.
There may be a blower motor back there.
