Truck made a strange noise at start-up the other day.
Similar to a belt squeal, but definitely different
I checked the belt, (even though it is new)
There was a glob of something on the surface of the idler pully which I cleaned off but that didn't cure it.
I noticed a black gummy substance at the boundary of the inner and outer portions of the AC compressor pully, so:
I turned off the a/c and restarted then the noise went away even after I turned the a.c. back on.
Any ideas?
Edit:
The a.c. clutch functions / stops if I pull the clutch relay fuse. ...............First off, I would do anything or have wrenches turned unless or until you have more frequency and consistency with the noise. If the noise gets more frequent, then that means you will be able to better figure out where and what the problem is......Sounds like it could be coming from your ac compressor clutch...If the noise does not come back with more frequency then I would not worry about it.
