Belt is dead, the dirt eroded the crap out of the groove sides to kill all grip. As well much dirt likely still stuck in belt carcass to make it slip even more. You ain't going anywhere without a new belt and then go from there, the tensioner may be dead too from dirt getting in it, they are not weather sealed. The pulleys with that much dirt may even have impacted it in the grooves to build the groove depth shallower and then all pulleys will need 100% of the concreted dirt chipped out before they will properly grab the belt again. You can look hard at the pulley and not see that and then the belt makes noise forever. The concreted dirt will appear to be part of pulley and requires extreme force to remove it. BTDT.
Belt squeal when A/C is on/off
2005 Altima 3.5 SL 134k mi
HOW LONG:
this has been going on for a month and i cant figure out what the problem is exactly. The A/C compressor is one year old, the original one seized last year, i believe the belt is also one year old.
POSSIBLE CAUSE:
there was a bad accident about a month ago and i was stuck in standstill traffic for about 3 hours and i needed to get back to base, the only other route was taking this car off-roading on poorly maintained sand roads (AWD&4x4's were getting stuck) i was able to make it thru but in the process i ripped off my skidplate and accumulated 1/2"-1" of sand practically everywhere in my engine bay. i thought i did a good job of cleaning out every nook and cranny i could of sand. where could sand be stuck in the belt that could cause the squeak/squeal, can i get it out with a socket wrench?
SYMPTOMS
I know i shouldnt have gone offroading but my COC told me to get back on base asap because i was already 1hr late to be secured for the weekend. it was a really bad situation, but i heard that the road didnt get re-opened for another 12-15 hours later, and it was the only paved road in-out from that direction.

SYMPTOMS
- I will start the car- 1/5 times it will squeal immediately on startup- stops squeaking for 30sec to a minute- then starts chirping for a solid 30 seconds
- the other 4/5 times it will be fine on start then start squealing for less than 15 seconds- then it will stop for about 30sec to a minute- then will either chirp or squeal for another 30 seconds
- it will squeal if the AC is on and im accelerating.
- the RPM's do noticeably dip when this happens, maybe 100rpm

Don't buy a cheap crap belt there either, that will only extend your troubles.
He means the tech there simply lubed the belt up to slip quietly instead of making noise. Wax does NOT increase friction, it is made of oil which SLIPS easier. The water from rain will simply rinse it off and you are back to making belt noise again. Oldest trick in the book.
