Please help I've had my 2002 ls1 ws6 Transam for about 3 years now. This summer I started using my a/c just like I would the years before but now my a/c now constantly throws out dirt from the vents and doesn't go away. Tried putting it full blast to blow out every thing but just continues to happen. Has this happened to anyone else? i need advice of what it can be i Greatly would appreciate it thanks

Wow, this is a first for me.

All I can think of is that the ducting behind the dashboard has come loose and its open somewhere........or the ducting itself is falling apart and that's what's coming through the vents.

Is it actual dirt......as in sand that's on the ground outside?

There's not any ducting to come apart it's hard plastic. If it's foam bits that's another story. Probably had a critter build a nest in the cowl panel it's sucking crap out of the cowl or it crawled through the cowl into the evap box and packed it full of crap. Had it happen before.

2 options pull the dash and tear it down or deal w it until it goes away. Unless you can pull the blower motor and see if that area is full of debris.
