Exactly, but if money is a concern, and the pain is a concern, he could do the bypass to delay the inevitable. Since it's May, he will have a few months to forget about it. When it gets cold, he will remember real quick, though. BRRRRR!

 

I have heard the same thing in my 2000 Z71!!! It had been doing it for a few years now. The weird thing is my heat gets hot and a/c still works but it will only blow out on the dash. I found a friend with a switch I replaced and it worked for a week or so now its back to blowing out on the dash and no where else. Got any ideas?

 

A sloshing could indicate a full evaporator drain pan caused by a clogged drain as well. If you have run the A/C much, the condensation will build up in the pan if the drain is clogged. Just a thought..

 

Well I've still not had a chance to check it out...things have been busy, but thanks for all the stuff to check and hopefully I'll get cracking this weekend.

 

By the way...I just popped the hood to take a peek around and the coolant reservior is completely dry...

 

i hear that same noise.................................OHhhhh its acase of beer on my floor LOL

 

hahahaha...maybe if I put a case of beer on my floor I'll forget about the noise...

 

youll only forget about the noise if you drink the case of beer

 

Yeah, the Vortec engines have a crappy seal at the waterpump/block. The sloshing water noise might be an effect caused by a loss of coolant. It's hard to spot, but surprisingly easy to fix with some good quality high temp RTV sealer and some good name-brand (like Fel-Pro) gaskets.

Takes a large strap wrench, and a flat wrench to fit your fan clutch, but it's very accessible, compared to older engine models.

 

So today I did notice there was water on the passenger floor...not alot, but some nonetheless...but it was a rainy day, so I'm not sure if the water has to do with a leak in cowl area or something else...
