Is it at all possible that a worn belt would cause this? The belt doesn't look in rough shape. When it was warmer out the ac would turn on, engine would idle up a bit and then I'd hear a noise (light clunk) and the ac light would start to blink.

Now it's colder out and the engine idles up and AC light stays on, but as stated, it sounds like my drive belt is squeaking.

My power steering pump pulley wobbles a little bit but I wouldn't think it would be enough to cause this...

Any ideas?

 

compressor clutch is gone/going?

 

Sounds like a bad pulley.....the belt will break at some point.

 

Yeah, I'm leaning more towards an AC problem. All the pulleys look good and tight except for the power steering one which wobbles a bit, but not enough to cause issues at the moment I don't think.

 

check the fan bracket or idler pulley as well.

 

Idler pulley looks solid, fan bracket is good.

Still, no squeak with AC on, squeak with AC off.

Idler pulley would have made sense since the idle goes up when AC goes on. Either way, it's weird and annoying.
