Question about 2006 Suzuki Swift
What gives a sound?
bt , what is Bt. but?
i think you meant, but cooling is not correct.?
you left out NOT?
that is ok, you must be using a CELL,
ok A.C school 101 (short)
it fails in 2 ways, electric or the Freon Loop.
2 ways. (one easy , 1 harder)
first pray it's electric (cheap and easy)
we always work that first. (electric, see why?)
the car has a A/C brain, it has many names but in English no tslang.
it is the "A/C logic module." or BRAIN.
This module protects the parts from damage, or overload.
old cars just melted. not smart cars. the brain is smarter.
My comments are typical of era.
So, you were smart, the clutch A/C, but failed to say,
IS IT ENGAGES, or NOT? the pulley spins all the time running.
but not the main shaft of the compressor, it must spin.
at full RPM !!! This is the brain DEMANDING A/C.
if not the BRAIN, has it turned off.
Keep in mind the brain on some cars is inside the BCM.
body brain, and not a separate A/C brain.
reasons for CLUTCH OFF.
the Brain sees and error , list of errors.
1: A\C not on.
2: fan not on (heater fan in cab shared by A/C)
3: evaporate frozen (packed in ice)
4: engine overload, (up hills, too steep)
5: engine overheat. obvious, but the sensor wire fell of can do that.
6: freon pressure too low, risking compressor destruction. and collateral damage max.
7: freon pressure too high.
8: normal, the brain sees normal cab temperature and cycles off.
saving fuel and wear.
what do i do? ,
use a volt meter to find the input that is wrong
to the brain. do not hot wire the clutch ever.
or risk #6 (i warned you, dont let hackers kill the good parts)
that is what we do.
if you find low pressure is true (logic true, ) then that is why.
the brain defeated the A/C due to that fact. a dead clutch .
check the pressure, mine reads 40psi, now.
my cheap walmart filler has a hose, and came with
simple instructions, read them and try that.
do not over fill the system.
$25 the kit costs. I keep one handy at all times.
