high pitch sound/click when turning the AC on !!

[looking4lc]

is it normal?

is there a service for the AC?

I just don't want have a problem during HOT summer here.

Hmm, click is probably the relay or the electromagnet clutch engaging. Sound may be the replaceable bearing on the AC idler pulley or the AC clutch slipping, but you won't know until you troubleshoot it. There are troubleshooting steps in the FSM.

I still haven't gotten to the root of my noises (replaced all pulleys, belts, bearings, etc.), think it is probably time to replace the entire clutch. Just making sure it is that since I can get a replacement compressor for a few more $$.

I have similar sound when I turn mine one, it seems to go away after 5-10 minutes. The best way to describe it would be a bird chirping very quickly. Is that what you are experiencing?

I have not tried to diagnose the problem yet, still working on pinpointing it.

Well I took it to Ac specialist and he said its fine.
Sound description is only when something engaging. It's not loud but defiantly you can hear/ feel it when turned on.
I could be wrong could be normal but I don't have other LX to compare it to. And would like to fix it if it not normal operation.

I'd recommend checking your serpentine belt and tensioner for a chirping sound when the AC engages. Might be a momentary slippage as the AC clutch engages and slows the belt briefly.

Oh I recorded the sound but don't know how to upload it.

Here it is.
Ac has been turned on/off 3 times

Good idea. I will look at that tomorrow. Thanks.

Sounds like the electromagnetic clutch doing its job.
