During normal acceleration i have experienced a noise that sort of sounds like running water (hard to explain) that is coming from behind the glove box. Could it be noise coming from the condenser? The a/c works fine and I'm pretty sure it is not coming from the belt. Truck is a 2000 2500 with the 360. Thanks

 

Most likely air trapped in the heater core - its behind the glovebox and this is very common. Hows your coolant level been? make sure your radiator is topped off and your overflow tank is up to the full line, (both with antifreeze or 50/50). Usually works its way out.

 

It might help to turn the heater on full blast with the radiator cap off, bring the truck up to operating temp so the thermostat opens up,and re-burp the system as well. I usually park on a slight incline with the front higher.It might just be susperstition, but I've neverhad a problem with air in the system.

 

I was recently cruisin' down the highway and looked over and noticed a puddle of water forming in the passenger side floor. I cut the air off and the flow stopped. Thank God I have vinyl flooring. Really helps with unexpected messes.

 

thanks for the feedback. Yea my coolant is down to almost none in the overflow tank. I'll put some in tomorrow. Thanks!
