A/C Chirp TSB

[Gizmo]

could not replicate lmao

I hear it all the time when the engine is cold, regardless of time of day. Once the engine warms up, it's hard to replicate. I hear it first thing in the morning, and after work. But if I'm running errands I do not get the chirp when the A/C engages.

yes, my next plan is to leave it overnight to they can drive it cold. it's just so much extra effort.

My surefire way to get it to chirp is to do the key fob auto start after its been sitting overnight.

mine doesn't chirp on startup though, only under load. the most likely (but not only) time for it to happen is accelerating from a stop when the engine is still cold.

I am at 35,700 miles. Just dropped my truck off for the 4th time for the chirp fix. Gave them the number.

Doubt the guy is on here, but there was one dude on FB that getting it replaced under the TSB may have fixed the chirp, but introduced a terrible clicking while running.

Well, picked my truck up after completion of the TSB. This is the second clutch installed in the 2 years I have had the truck, but the part number for the clutch for the TSB is different, so I assume something changed.

Either way. First time starting the truck without a double chirp in months. Oddly enough, while waiting on my keys, I heard a double chirp after a vehicle started. Turned to look. Shocker, a Tacoma.

It took about 6 weeks for the chirp to return on the last clutch. Hopefully, it stays gone now.

I just saw this posted on Facebook. Does anyone know what the actual repair is?

I have had this chirp on start up since day one on my 2025 TRD O/R. I never really thought much about it as I thought it would wear in over time. But it is still there at 5k miles. Weird coincidence, but my 2014 Lexus ES350 has had a similar chirp that goes away after a belt change for a year or two but has always came back- I live with it because I don't see an issue but perhaps with the Taco I will let the dealer give it a shot to fix.

i know the guys in my local parts department so i ordered mine before going in this week for my 20k service and to get it confirmed. my service writer was confused when i told her that the part was already ordered since they confirmed the noise in the service drive.

part is currently on backorder until mid june is what i was told.

Had my 2024 take care of at 35k on the clock. I had complained before, so it was on record - originally claimed it was the high pressure fuel pump. Anyway, it was the first one they had seen and a couple of hour job turned into 2.5 days w/out my truck. There weren’t any issues, but they said they wanted to take their time and do it correctly the first time. I had a rental, so no problem. No more chirping.

Just got mine done.. no more annoying chirp.. truck runs great.. they kept overnight cause they said the part in the tsb was superseded and was back ordered but they were able to get it from a nearby dealership that had one in stock from a customer that probably didnt show up for his appointment for the same issue. I think my ac was constanly on before cause now when the ac is off it doesnt blow cold air like before. Part alone is $600.. get urs fixed sooner than later if you have this issue
