I just bought a used 2001 Sentra XE and the Air Conditioner does not work.
The light on the A/C button comes on, but I don't not feel a load on the
engine, or hear the compressor clutch engage.
This leads me to believe it could be as simple as a fuse. The trouble is,
the fuse cover and legend was missing from the car. I do not know which
fuse to locate.
Do any of you have a diagram you can post, or possible point out which
fuse(s) I need to check on this panel?
fuse number 15 (10A) is for the A/C. located 2 fuses over from the white center clip on the left side middle row.
the blower motor fuses are 14 and 16, both 15A
the fuses on the right on each row are spares (10A, 15A, 20A)
I did some tests tonight on the A/C relay and found some strange readings
for resistance.
All pins from the A/C relay measured zero ohms when referenced to the
compressor clutch lead.
I ended up cutting the wire to isolate any ground shorts and connected the
A/C clutch directly to the battery via a fuse and clipped wire leads. The
compressor engaged, but the air coming out of the vents was still warm.
There must be other sensors in the circuit which are not activated. I'm
going to pick up a Haynes service manual and hope that I can troubleshoot
the rest of the circuit with the book.
In the mean time, here are some pics of the process. If anyone has a
diagram/schematic, or any tips I'd sure appreciate it!
ok man have you checked the freon level. the car probably ran out or somelet the air out. About 5 years or 100000 you should have it refilled.
also it could be the ac compressor.
There is a clutch on the a/c unit. I wonder if that is what took a dump man. I will tell you this...if it is getting power, but no cold air, AND you are not feeling it kick on when you drive....something is wrong. I think even with no freon, you would still feel the kick. I hate to say it bro...but i think you may need to change out the compressor.
Hope it works out for ya man, perhaps take it somewhere, and see if they will test your freon level for free.
If your fuses are good
and your relays are good
and your freon level is fine
and your a/c compressor is getting power
it could really only be the clutch on the compressor or the compressor itself
I went to the Nissan dealer and they were nice enough to print out a
schematic/diagram of the A/C system.
It seems I have check everything except the "themo control amplifiier".
The print out does not say where to locate the sensor in the car, nor does
it give a photo.
Would I be lucky enough to ask someone for a picture, or location of this
device on my Sentra!??
Thanks everyone
