My A/C doesn't work at all,
even after I tried to refill the refrigerent.
When I check from the main fuse box for electric
cause, I focus on the relay for the A/C clutch.
I test with an ohmeter and found that one of the wire connected to this relay always gave me a flat
signal, even I switch on the A/C. From the electr.
diagram of Haynes, I feel that when I turn on the
A/C, the clutch should be engaged, so this wire
should be a positive signal(+12V), am I right??
when I connect the other wire of the relay to the
"+" head of the battery, I saw the clutch is engaged, and I can feel some cool(not cold) air.
btw: I always heard a 'click,click' noise from
under the hood whenever the engine is run.
At first, I guess maybe the timing chain
tensioner acts. But now I doubted maybe it
comes from the clutch, because when the
clutch is engaged, the noise disappeared.
Can you give me some suggestion or advice??
Thanks very much!!
