AC A/C Air Conditioner Fuse Location

Hi,

I need to check the AC fuse on my 2004 Sedona, the compressor does not come on but the AC green light works and in defroster mode the compressor does not work either.


Where is the AC fuse? I looked under the Relay Box under the hood and in the left hand side fuse panel. There are no fuses labeled AC or AIR COND or anything like that. I have the 2003/2004 service manual and I cannot find any info on the location of the AC fuse.

Is it labeled something else?

Please help.

Please note my signature line below and fill in your profile info. The green AC light on the switch comes on because the switch is functioning properly. The first step I would take in this situation is to unplug the connector at the compressor, and using a test light, check that power is getting to the compressor. If it is, the compressor is faulty, If it is not, you may have a refrigerant leak, bad relay, faulty pressure switch, etc..

NEW MEMBERS- Please fill in your profile info in the "user CP" link (year, make, model, location, etc..), it makes it easier for us to help you.

Thanks mattybyzf !

Found out on another site the fuse names:

Kick Panel: Engine 10A
Under the hood box: C/FAN2 30A

Both fuses are intact and not blown.

So, basically came to the same conclusions, if I have a freon leak, the system will not activate and/or faulty tri-pressure switch and other stuff.

I have static pressure on the "low side" of the system, about 70psi, although this does not tell me much. I do know from past experience that the static pressure is higher and when the compressor kicks in active mode, the the pressure drops to the operating range.

At this point, since it is not a simple electrical fix, and I do not have A/C equipment beyond a low-side charge hose with a gauge. I will need to have someone take a look.

Thanks again

Fixed - AC A/C Air Conditioner

Since electrically, I checked everything that I could I broke down to take the van to the dealer. Initial check showed refrigerant to be low. They were able to pressurize the system to get the clutch to engage and then all of the refrigerant exited through the front of the compressor. New compressor and drier were installed, system flush, and refrigerant replaced. The drier did not implode when the compressor gave way, but metal shavings were caught in the drier.

Also, I read in other posts where there was a rattling sound when first starting the van and then worse when in reverse, then later, when warmed up, the noise would be lessened. I had these symptoms for a long time, I assumed a bad motor mount (which I do have in front), but most, if not all of the growling, rattling sounds were coming from the A/C compressor.
