Hit ac button, immediate squealing

Hey, 2010 tacoma here. Its hot out, i hit the ac button and major squealing under the hood. Compressor shot?

 

As soon as i hit the ac button it screams loud. Stops screaming as soon as i turn it off. Is it safe to run for a few? Im afraid of bustjng the belt

 

compressor locked up or clutch has failed

 

Is this a possible diy?

 

There are threads about replacing the pulley/clutch. Should verify by opening hood and looking at the AC clutch while someone turns the button on. The center should go from stopped to spinning.

 

could always change the belt first to see if that's the issue only $20 or so

 

I just replaced my clutch, it wasn't terrible. Compressor is more involved and requires replacing a few other things and evacuating/recharging the entire AC system. Compressor replacement from a shop will run around $1k.

 

FREE: open hood and look at the AC clutch while someone turns the button on. The center should go from stopped to spinning.

 

ouch how many miles on your truck when this happened? your in the south so u must use it often

 

Toyota had to replace it once at 40k miles under warranty right when I bought the truck...and I had to replace again at 105k. I barely ever use my AC, lol.

 

wow, I barely use my AC too only when the passengers start to complain, mines got 95k miles hopefully I don't need to do any AC work im off warranty

 

Ugh. Ok will check when i get home. What would spinning vs not mean?

 

Surprised only one person said the pulley.

 

I think if spinning the clutch is engaging working

 

jup x2

 

There's a pulley(ring) wrapped around the clutch(center). When the A/C is off the clutch is not spinning(think of a tire not spinning) but when the A/C is on the clutch should be spinning(cycling on and off). The squeal may be because the clutch is locked up and we it engages the pulley it makes the pulley stop.

 

Pulley meaning the clutch?

 

Gotcha, which is bad for the belt i imagine. Christ the second i hit 100k stuff begins to happen.

 

there are pulleys that the serpentine belt wraps around these also have a tendency to wear out and need replacement they start to chirp

 

don't say that im at 95k miles
